DSLR vs SLR Camera - Difference and Comparison

SLR cameras allow expert photographers to change lenses and choose the right lens for the given shooting situation. DSLR refers to SLR cameras that take digital photos and the few cameras left on the market still using film are simply called SLR cameras.

DSLR cameras are great for budding photographers because they offer live previews and do not waste film when photographers make mistakes. There are more DSLRs available in the market so they tend to be cheaper. Film SLR cameras, on the other hand, offer slightly better quality of color, tone and contrast.

Technology

DSLR and SLR cameras both reflect light that enters through the lens using a mirror so that an image can be seen in a viewfinder. However, an SLR camera uses a film made of plastic, gelatin and other material to record the image - a DSLR captures the image digitally, on a memory card.

This comprehensive video explains the difference between DSLR and SLR cameras very well:

Required Materials and Processing

Memory cards used in a DSLR camera

A DSLR requires a flat memory card to store all its images in digital format. This little card can store thousands of images, and the user is able to delete any unwanted images instantly to make space for more. The card is reusable and the image can be seen instantly on camera or a computer, and can be printed right away with an external printer.

An SLR requires a roll of film usually made of a plastic strip lined with thin layers of gelatin containing silver halide crystals, which react chemically to light to form a photographic image. This chemical reaction needs to take place in a photo lab and requires a few hours to print. The film is not reusable, and can hold only upto 36 photos.

Film used in the SLR camera

Picture Quality

Both DSLRs and SLRs allow the photographer to view and focus the image using the attached lens. The first DSLRs had poorer picture quality than film SLRs. Advances in digital technology, including the number of megapixels available, have almost completely erased this difference.

Speed

Shutter speed depends on the type of DSLR or SLR. Entry level SLRs typically have a speed of 1 to 1/1000th of a second; the Konica Autoreflex TC has a shutter speed of 1/8 to 1/1000. Most modern DSLRs have shutter speeds up to 1/4000th of a second, much as high end ones can have shutter speeds as high as 1/8000 and above.

Optical Viewfinder

Both DSLR and SLR cameras use optical viewfinders to take pictures. DSLRs can also come with LCD viewfinders, like in point-and-shoot digital cameras, which is handy for situations when an optical viewfinder cannot be used, say underwater photography.

Complexity

Both DSLR and SLR cameras are similar in that they have several settings that the photographer controls, and can be difficult for beginners to use. They also require maintenance in keeping the lens and sensor clean and dust-free. DSLRs are more beginner-friendly as they allow the photographer to preview the image or take multiple images without wasting film. They also typically come with some in-built settings for different scenarios, and the user can switch to the LCD viewfinder if they wish.

Price

On Amazon.com, DSLR cameras range from about $500 to several thousand dollars, depending on the quality. There are far less film SLR cameras available, and the cost ranges from under $100 for a second-hand basic camera to around $1000. However, SLR cameras have the added cost of film rolls.

Other Pros and Cons

DSLRs allow photographers to store thousands of pictures on a memory card, while a roll of film in an SLR camera can only hold about 36 photographs. DSLRs also allow the photographer to preview the image after it has been taken, and make it easy to upload the photo to a computer to edit or print.

Why some photographers still choose film over digital

In an article for the BBC, analog photographer Stephen Dowling writes about why some photographers even in this day and age choose film over the more convenient digital photography option:

Some [photographers] may want to work with much larger formats (their digital equivalents can be very expensive), while others may prefer the look of film's grain, or the less saturated colours of certain films. Some want to be in control of the entire process, from the taking of the pictures to developing their photos in a darkroom and slowly seeing prints emerge under the red light - an alchemical process that still, somehow, seems like magic.

What is a DSLR?

DSLR is one of the top-rated cameras these days due to its advanced and great features. DSLR works more or less like SLR. This camera uses a mirror to reflect the light which is coming from the lens into the optical viewfinder. Moreover, this camera also provides a live digital view on the LCD screen. DSLRs use interchangeable lenses, which means the lens can be adjusted according to the shooting style. Moreover, this camera uses a memory card for storing and can store thousands of pictures. Most DSLRs are available in a single color and with a monitor. Moreover, DSLR can also help in recording videos.

What is SLR?

SLR refers to “single-lens reflex. Single-lens means the image can easily be seen through the lens of the camera. And reflex means it can be seen through a mirror. SLR contains films on which the images are recorded, and later on, these can be developed for creating reality. SLR film can only record a limited number of images at one time, and for further images, you have to change to film roll. SLR cameras have modern bodies with two-tone colors. These cameras also have more buttons but do not contain any monitor.

DSLR vs. SLR Pros and Cons

Pros and Cons of DSLR

Pros of DSLR:

  • DSLR has an extra feature of filters and flashes, which makes the pictures stand out.
  • It has a high-speed shooting mode, which provides the photographer live pictures through the viewfinder.
  • It has a large sensor size, so the images are more precise than other cameras.

Cons of DSLR:

  • High price tag. It is more expensive if we compare prices between compact cameras vs. DSLR.
  • Another disadvantage of DSLR cameras is that they are very complex with work due to their advanced features.
  • DSLR cameras are bigger and heavier than other cameras, making them difficult to carry compared to digital camera vs. DSLR.

SLR Pros and Cons

Pros of SLR:

  • SLR cameras have the ability to frame up the photo and focus accurately.
  • A large variety of backup ranges of accessories and lenses make SLR a flexible unit system to work with it easier.
  • SLR also has an exposure counter which tells about the remaining number of pictures.

Cons of SLR:

  • SLR cameras are quite heavy and bulky compared to digital cameras, especially if you need to carry some additional filters, flash, and a spare film inside your bag.
  • The complexity. Sometimes, to take a perfect shot, you may need to change the lenses and filters quite often. For beginners, we recommend using a rangefinder or some advanced compact camera.
  • It’s not digital. In the digital age, the advantages of using the digital camera have become evident for most users. Also, the quality could be the same or even better, except for SLR fans who prefer to have complete manual control over the process.

FAQs

Which is Better, SLR or DSLR?

DSLR  is better. Because it provides a live preview and doesn’t waste film when the photographer makes mistakes in taking pictures. You can easily erase pictures from your memory card.

Why Use a DSLR Camera?

DSLR can be used for photography as it gives sharpness, clarity, and better resolution as compared to many other cameras.

What Are the Types of Cameras?

There are many different types of cameras out there. But the main four types are DSLR, mirrorless, compact, and bridge cameras.

Conclusion

DSLR and SLR both are popular cameras used to take pictures. The main DSLR and SLR difference is in their image technology. If we look at the definition of a DSLR camera, it is the camera that takes digital photos. While in the definition of a SLR camera, it is the camera that gives the ability to change the lens for a shoot situation. DSLRs are basically a new form of SLR cameras. From SLR to DSLR, a lot of features have been added to the camera. and now it is the most popular camera to use for photography whether we compare DSLR Vs. digital SLR or compact camera vs. DSLR.

Comparison of compact and SLR digital cameras

The choice between a compact (point and shoot) and a digital SLR camera is often the first fundamental purchase decision at the beginning of photography. Not only does it potentially have financial implications, but it can also determine the types of shots you can take. This article, leaving all the marketing bullshit behind the scenes, focuses only on the most important differences between different types of cameras - thereby helping you decide what is best for you and your shooting style.

Compact Camera SLR camera

General

What really separates a compact (point and shoot) and a SLR camera? Strictly speaking, the viewfinder of a SLR camera only shows exactly the same picture that will fall on the camera sensor (more on this below), but in practice this is not the only difference. And while the line between cameras continues to blur, the following three differences typically continue to exist:

  1. Viewfinder unit
  2. Interchangeable or fixed lens
  3. Sensor size

There are also a few minor differences (which vary by camera brand or model), but the above three often have the biggest impact on shooting. The following chapters focus on what each of these differences means in practice and how it will affect the style of your photography. Finally, we will also discuss a few less fundamental differences between the two types of cameras.

Notable exceptions: Four thirds (4/3) cameras use interchangeable lenses but do not use the standard reflex viewfinder (such cameras are made by Olympus and Panasonic). Some budget DSLRs may come with a fixed lens, and some high-end compacts may have sensors that are almost the size of a DSLR - but these are the rare exceptions to the rule.

However, something should be mentioned right away: SLR cameras are usually s are much more expensive than compact s, mainly due to the three differences above (we'll discuss why later). In addition, unlike a compact camera, buying a SLR camera does not exhaust costs; you may need additional lenses, an external flash, and other accessories that end up costing more than the camera itself.

1. Viewfinder

Unlike compact cameras, the SLR camera's viewfinder will show exactly what hits the camera's sensor when you press the shutter button:

Compact Camera SLR camera mirror lowered mirror raised

When you press the shutter button on an SLR camera, the mirror goes up and the light that has been redirected to the viewfinder hits the camera's sensor. Hover over labels to see how it works . Raising the mirror just creates that characteristic click that we used to associate with SLR cameras.

The viewfinder of a compact camera is just trying to evaluate the image that will hit the sensor, which is potentially less accurate. Compact cameras can also use what's called an electronic viewfinder (EVF), which tries to replicate the viewfinder of a DSLR using the image from the sensor.

Note: This is in fact why DSLRs are referred to in the technical literature as "single lens" - because the same lens is used to capture the image in both the viewfinder and the sensor. This terminology, however, is misleading, because SLR cameras can just be used with interchangeable lenses - unlike compact cameras.

The need for a prism and a mirror is one of the reasons DSLRs are more expensive (besides sensor size) and can have a significant impact on camera design and manufacturing. However, in practice, the size of the sensor and the ability to change lenses will certainly have a greater impact on your photos than a reflex viewfinder. This is especially true given the widespread use of the screen instead of the viewfinder.

On the other hand, if your job requires you to see exactly the image that will be taken, you will probably need an SLR camera. However, one can almost always see0071 How would look like a picture using the screen of a compact or SLR camera in hover mode and evaluating the histogram.

2. Fixed and Interchangeable Lenses

The fact that SLR cameras are interchangeable lenses is perhaps the first noticeable difference that is noticed or known in advance. Yes, many compact cameras can use special adapters (especially expensive models), but the lens itself remains on the camera.

photo by Scott Bourne

Why do I need multiple lenses? It's a difficult, if not impossible, task to design a single lens that can be used for the wide variety of styles used by photographers - without compromising quality and portability. Each style is much better implemented with its own lens adapted for this purpose.

In practice, the ability to use different lenses usually means that:

  • you will be able to use a wider aperture (small f-stops), which will reduce the depth of field, as well as shoot in low light.
  • you can use specialized lenses such as ultra wide angle, fisheye or high power telephoto lenses to give you more creative options.
  • you can potentially get better image quality than , primarily because a specially designed lens is likely to better suit the shooting task.

For example, portraits typically use a wide open aperture (f/2.0 or less) to get a smooth background and highlight the subject. On the other hand, for architecture, you can use an ultra wide-angle lens, which was designed to minimize distortion (which would cause straight lines to curve). None of this is possible with most compact cameras.

Extra wide angle of view Shallow depth of field

However, using more than one lens also means that:

  • you will need to carry multiple lenses if you plan to shoot in different styles and different subjects. This reduces portability.
  • you will have to change the lenses whenever you want to change your shooting style. This can disrupt the shooting rhythm.
  • Your camera's sensor can get dust whenever you change lenses. This may reduce the image quality. In addition, dust can be difficult to remove.

Of course, to reduce any potential inconvenience, you need to find your favorite all-round lens and use it most of the time. In addition, the built-in lens of high-end compact cameras can sometimes provide better image quality and a wider range of applications than a bundled or budget DSLR lens. However, if you are not shy about spending, compact camera lenses are unlikely to be able to oppose the best models of lenses for SLR cameras.

3. Camera sensor size

Compact cameras typically use much smaller sensors than SLR cameras. This subtle difference between DSLRs and compacts is less well known, but it will almost certainly have the most noticeable impact on image quality.

Compact camera pixels SLR Camera Pixels

What does this mean in practice?

  • Cost . Larger sensors are much more expensive to manufacture, and as such they usually require more expensive lenses. This is the main reason DSLRs cost so much more than compact ones.
  • Weight and size . Large sensors require much heavier and larger cameras and lenses, as the lens must capture and deliver light over a larger area. In addition to reducing portability, the disadvantage of this solution is that a person becomes more visible with a larger camera and lens (that is, candid photography of people is more difficult).
  • Depth of field . Large sensors provide shallower depth of field at the same aperture. For example, a compact camera lens at f/4.0 is unlikely to provide a blurry background for a portrait, while the same f/4.0 on a DSLR will certainly create a soft, blurry background (depending on the distance to the subject). This can be an advantage for portraits, but at the same time a disadvantage for landscapes.
  • Visual noise . For the same number of megapixels, larger sensors have larger cells* (pixels), as shown above. This increased light collector area means that the pixels will be more sensitive to minimal amounts of light - resulting in less visual noise. This means that a DSLR can usually deliver much higher ISO than a compact camera for the same level of visual noise.
  • Dynamic range . Another consequence of the large physical size of a pixel is that SLR cameras can usually capture a wider range of light and shade between absolute black and absolute white (i.e., have a wider dynamic range). This reduces the risk of blowouts in the sky or other bright objects while retaining more detail in deep shadows.

*Technical Note: Strictly speaking, a cell is not equivalent to a pixel because a pixel is created from multiple cells, but we use the more common word "pixel" when referring to a cell. You can read more on the topic in the article “Digital camera sensors”.

Large dynamic range High number ISO

It's important to understand that sensor size differences are just a parameter, one size isn't necessarily better than the other, so it makes sense to evaluate how the pros and cons of each suit your shooting style. This topic is covered in much more detail in the article on digital camera sensor sizes.

Other differences

In addition to those already discussed, each type of camera may also have other features, depending on the specific manufacturer or model, including:

Advantages of compact cameras cameras are also capable of this)

  • Large set of creative modes
  • No moving mirror/shutter parts to fail after 10-100 thousand shots
  • SLR benefits

    • Fast auto focus
    • Much faster shutter lag (interval between button press and start of exposure)
    • Fast continuous shooting
    • Shooting in RAW (although most top compact cameras allow this too)
    • Ability to make shutter speeds longer than 15-30 seconds (in manual mode)
    • Full exposure control
    • Ability to use an external flash (but many top models of compact cameras have it)
    • Manual focal length control (by rotating a ring on the lens, as opposed to pressing a button)
    • Large sensitivity range ISO
    • Possibility to replace only the camera, keeping all lenses

    However, most of these differences result from the fact that SLR cameras are much more expensive than compact cameras, and are not fundamental qualities of each type. If you spend enough money on a top-of-the-line compact camera, it can have quite a lot of features normally found in DSLRs.

    Compact vs. SLR Comparison Summary

    Preference for one camera type over another really comes down to flexibility and potentially better image quality versus portability and simplicity. This choice often depends not only on the individual, but also on what is best for the given shooting conditions and the intended use of the image.

    Compact cameras are much smaller, lighter, less expensive and less visible, but DSLRs offer shallower depth of field, more shooting styles and potentially higher image quality. Compact cameras are probably much better suited for teaching photography, as they cost less, make shooting easier, and are a good all-rounder for many types of photography without the hassle. DSLRs are much better suited for special applications and when weight and size don't matter.

    Regardless of the cost, many people prefer to have both types of cameras. This way they can take a compact camera with them to parties and long walks, but have a DSLR on hand for when they have to shoot indoors in low light, or when they intend to shoot exclusively (for example, landscapes or events).

    TECHNOLOGY

    The range of mirrorless cameras has grown significantly, but is it time to switch to mirrorless? We've put together a list of the differences between DSLR and mirrorless cameras to help you decide.

    With the EOS R system now including both full-frame and APS-C sensor models, not only professionals but also hobbyists will find a camera with the benefits they need in our range. However, whether your goal is to replace an old camera with a newer one or replace a compact camera with an interchangeable lens digital camera, in this article we will answer the question of which is better - mirrorless cameras or more traditional SLR devices.

    To help you make your choice, we'll look at the differences between DSLRs and mirrorless cameras, as well as provide expert insight from Mike Burnhill, Lead Product Specialist, Canon Europe.

    • Digital SLR & Mirrorless Cameras: The Ultimate Choice

    There is a term DSLR which means "single lens digital reflex camera". "Mirror" in this case means the presence of a mirror that reflects light towards the viewfinder. The mirror must be movable so that light hits the image sensor behind it, which requires a rather bulky mechanism - as a result, the cameras are more bulky and heavy, and their development is associated with complex optical design problems.

    B mirrorless cameras such as Canon EOS R7, there is no mirror system - along with this, the light entering through the lens hits the image sensor directly. The electronic viewfinder displays the image from the sensor, which means that, unlike the optical viewfinder of a digital SLR camera, users of mirrorless devices can preview exposure effects. Mike Burnhill of Canon Europe says: "The electronic viewfinder on mirrorless cameras allows you to preview the effects of exposure before the photo is taken."

    DSLR and mirrorless cameras body size and weight

    retracts the mirror to allow light to reach the image sensor By removing the mirror, the camera can be made lighter and more compact - especially noticeable when comparing the EOS R7 and EOS R10 with similar models with a mirror system, such as the Canon EOS 7D Mark II or EOS 90D".

    Lifestyle content creator Diana Millos used the EOS R10 to shoot culture and architecture in Andalusia. She says: “The EOS R10 looks like a toy when compared to bigger cameras like my EOS 80D. I like that it's compact and light, but still powerful."

    DSLRs such as the Canon EOS 7D Mark II provide high image quality but are not as compact due to the need to integrate a mirror system into the body.

    Mirrorless cameras such as Canon The EOS R10 delivers the same high level of quality and useful features in a more portable and lighter package.

    Lens mounts: an advantage over mirrorless cameras?

    The EF mount, which is used in most Canon DSLRs, was introduced in 1987, making it a tried and tested system. There are hundreds of options available from the EF Lens range to help you find the right focal length, and more affordable EF-S lenses are available for EOS cameras with APS-C sensors.

    However, the RF mount used on EOS R System cameras offers many innovations. “The RF mount is designed with the future in mind,” says Mike, “and offers fast lens-to-camera interaction as well as more mount pins to support additional features.” These include high-performance autofocus, real-time digital lens optimization, and advanced control options, including a control ring on RF models.

    Instead of having to adjust the design to the dimensions of the mirror between the mount and the image sensor, RF lens designers can create models with a shorter back-span, which improves optical quality. This allows them to create faster, higher quality lenses, as well as innovative solutions such as the RF 5.2mm F2.8L DUAL FISHEYE, which allows 180° VR footage to be captured when mounted on compatible full-frame cameras.

    At the heart of Canon's EOS R mirrorless system is an innovative wide-diameter RF mount with short trailing edge and ultra-fast lens-camera interaction.

    Lenses and Compatibility: Can old lenses be used with a mirrorless camera?

    If you already own an EF or EF-S lens, you can easily use it with EOS R System mirrorless cameras without sacrificing quality or functionality, thanks to the EF-EOS R Mount Adapters. You can also use select lenses in both formats ( in particular, if you have a favorite or specialized lens, which has no analogues in the RF line yet) and enjoy the benefits of both systems. What's more, a mount adapter with a lens control ring and even a model with a plug-in ND or polarizing filter are available, options that allow you to expand the functionality of EF lenses compared to their use on digital SLR cameras.

    However, it is important to note that RF lenses cannot be used with a DSLR. So if you like a particular RF lens, you'll need to purchase an EOS R system mirrorless camera to work with it. access to EOS R system mirrorless devices. “By offering the RF mount to more users, we are also giving them access to a new generation of lenses designed specifically for this mount, lenses that could not be made for SLR cameras,” says Mike. Thanks to the crop factor of APS-C image sensors, full-frame lenses such as the one in the image provide 1.6 times the focal length when mounted on APS-C cameras.

    Optical and electronic viewfinders: which is better?

    DSLRs are equipped with optical viewfinders, which some photographers prefer to use because direct interaction with the scene is important. The electronic viewfinders of the past generations had a number of drawbacks, such as a long display lag, but they are getting better and better - in the new cameras of the EOS R system, the electronic viewfinders offer a high refresh rate of up to 120 fps, which means almost no delay, and some additional benefits.

    In particular, if you are using an EOS R System camera, Exposure Simulation allows you to preview exposure effects, Picture Style, and other settings both in the viewfinder and on the rear LCD screen. On DSLR cameras, exposure simulation only works when viewing the scene on the rear screen in Live View mode - this option is not available for the viewfinder. The electronic viewfinder also lets you compose and focus in low light, while the optical viewfinder gives you exactly what you see with the naked eye. When shooting movies, the electronic viewfinder on the EOS R system cameras offers the same manual focus assist display as the Canon Cinema EOS cameras.

    Wildlife photographer Dani Connor, who used the EOS R7 on a trip to find the endangered Iberian lynx, found that the electronic viewfinder changed the way she photographed.

    “With a DSLR camera's viewfinder, it's often easier to take a test shot and view the image on the back screen, then adjust the settings if necessary,” she says. “However, with a mirrorless camera, you can see exposure effects without having to look away from the viewfinder.

    Whether I need to quickly react to the actions of a wild animal or constantly adapt to changing lighting conditions, I can quickly adjust ISO or shutter speed and instantly see what the photo will look like.”

    The electronic viewfinder of a mirrorless camera uses a compact version of the same high resolution display technology as the camera's rear LCD screen. One of the advantages of such a system is that it allows you to see what the camera sees, even in very low light conditions where absolutely nothing can be seen with the naked eye.

    A mirror in a digital SLR camera reflects light into the optical viewfinder using a pentaprism so that the image does not look upside down. The advantage of this is that it happens instantly. “The electronic viewfinder will always have some lag,” says Mike. “Digital SLR viewfinders operate at the speed of light—it can’t get any faster.”

    Image quality: Is it true that mirrorless models offer better photo quality?

    “Shooting with DSLRs and mirrorless cameras isn't that much different in terms of the quality of the final image, but a lot of the difference is in the shooting process,” says Mike.

    — For example, the RF mount offers a faster interaction between the camera and the lens, which allows you to cope with the effects of diffraction and aberrations - such defects are corrected by the camera in real time. This instant processing means that the new cameras deliver higher overall image quality.”

    In some situations, mirrorless cameras such as the EOS R7, which offers burst shooting up to 15 fps. with mechanical shutter and 30 fps. with an electronic shutter at full servo AF, will provide a much higher percentage of quality photos than the EOS 7D Mark II or EOS 90D, which offer burst shooting at 10 fps.

    New mirrorless cameras such as EOS R7 offer advanced features for content creators including video support 4K 60p with Intelligent Object Tracking - not available on DSLRs such as the EOS 7D Mark II and EOS 90D.

    Autofocus: DSLR vs. mirrorless cameras

    EOS R system mirrorless cameras, including the EOS R5, EOS R6, EOS R7 and EOS R10, use Canon's new Dual Pixel CMOS AF II autofocus system, where each pixel of the image sensor is used independently. only for imaging, but also for focusing, which is different from the separate phase difference focus sensor on cameras such as the EOS 7D Mark II and EOS 90D.

    One important advantage of these mirrorless cameras is the ability to select an AF point anywhere in the frame. “It's not possible with a DSLR,” Mike explains. “Moreover, it ensures that these cameras support features such as face, eye, and animal tracking. For example, the camera will maintain focus on the eye of a flying bird, no matter where it is in the frame - again, this is not possible on a digital SLR camera.

    "However, some professional DSLRs are equipped with a separate autofocus chip, and while the overall functionality of the autofocus system may be lower than on newer mirrorless cameras, this chip may make it faster in some situations."

    Quick electronic shutter and Animal eye-tracking autofocus available on newer mirrorless cameras such as EOS R7 and EOS R10, make them excellent solutions for photographers of all levels. "I like a wildlife photographer loves being able to maintain focus on an animal's eyes,” says wildlife specialist Dani Connor. “This opens up new possibilities for me that are not available to users of digital SLR cameras. ”

    Mechanical shutter and electronic shutter

    Several DSLRs, notably the EOS 90D and EOS-1D X Mark III, offer an electronic shutter in addition to the mechanical shutter, but most DSLRs only have a mechanical shutter. All mirrorless cameras of the Canon EOS R system, in turn, have shutters of both types.

    When using the electronic shutter, the mechanical shutter is locked in the open position and the image sensor reads the data electronically. The biggest advantage of this is that shooting can be completely silent - not just quiet like the S (Soft) option on some cameras, but truly completely silent. This can be an invaluable advantage when shooting shy animals, sleeping children, or the intimate setting of a wedding.*

    The electronic shutter also enables faster continuous shooting. “With a mechanical shutter,” says Mike, “the highest burst rate is 16 fps. on the EOS-1D X Mark III, a professional grade camera. In electronic shutter mode, the much more budget-friendly EOS R10 shoots at up to 23 fps, while the EOS R7 shoots at 30 fps, the same speed as the professional EOS R3, but at a third of the price. ".

    In electronic shutter mode, a lag defect can become a problem, which is noticeable, for example, when shooting fast-moving objects, such as a golf club or a helicopter propeller, such objects can change position during the entire frame reading period, resulting in they look distorted in the final image. The newer mirrorless cameras have largely eliminated this defect, but we recommend using a mechanical shutter for shooting fast action.

    Shooting with the electronic shutter under artificial lighting, especially under fluorescent lighting, may be problematic if the flickering speed of the light does not match the shutter speed. For similar reasons, using an electronic shutter flash can result in uneven exposure across the frame.

    Family photographer Helen Bartlett finds the ability to shoot completely silently with the EOS R System cameras incredibly useful. Because the silent shutter releases little distractions, especially when they're sleeping, she can capture more natural photos of them.

    Battery Life: DSLRs and Mirrorless Cameras

    DSLRs are often said to have longer battery life than mirrorless cameras, mainly because the electronic viewfinder of a mirrorless camera requires power to function. while the optical viewfinder of a DSLR does not require power. However, in practice, battery life will vary depending on how you use your camera—for example, both types of cameras will consume more power when using the flash, and using the LCD screen on DSLRs typically uses more power than using the same function on a digital SLR. mirrorless cameras. Mid-range DSLR like EOS 90D, allows you to take 1200 or more shots with the viewfinder and 450 shots with the LCD screen, while the EOS R6 mirrorless camera allows you to take 380 shots with the viewfinder or 660 shots with the LCD screen in maximum performance / maximum responsiveness mode. In power-saving mode, this figure is 500/770 shots when using the electronic viewfinder / LCD screen, respectively.

    For professional cameras, the difference is even greater: for example, the EOS-1D X Mark III can shoot up to 2500 images with the viewfinder on a single charge, but only 600 images in Live View, while the mirrorless EOS R3 provides 620 shots with the viewfinder and 860 with LCD screen. So if you prefer to use the rear LCD screen, mirrorless cameras can give you more shots without recharging the battery.

    DSLR vs. Mirrorless: The Ultimate Choice

    Both mirrorless and DSLR cameras have their pros and cons. Your choice will depend on the genres of photography you work in and the benefits you require from your camera and lens.

    If you're looking for a lightweight, high frame rate camera for travel photography, a mirrorless camera like the EOS R10 is ideal. If you want to use the next generation of RF lenses, the EOS R Mirrorless System is the way to go - in addition to the camera's built-in image correction and powerful tracking autofocus, you can use your favorite EF lenses via EF-EOS R adapters.

    If you want to view the image in the viewfinder with the exposure settings applied, a mirrorless camera with an electronic viewfinder is fine - but the Live View mode on a DSLR provides the same effect, while the optical viewfinder found on such cameras eliminates even a small amount of lag that is still inherent in the fastest electronic viewfinders on mirrorless cameras, as well as longer battery life.

    Advanced AF features such as animal eye AF and vehicle AF are only available on EOS R system cameras, but separate AF chips in DSLRs can provide even faster performance. EOS R System cameras allow you to shoot with both electronic and mechanical shutters, while most DSLRs only offer mechanical shutters. If absolutely silent shooting is important to you, and you do not photograph fast moving objects, where operation with an electronic shutter can be accompanied by a lag defect, models with an electronic shutter are suitable for you.

    From ergonomics to autofocus, from shutter type to shutter speed, if you have the opportunity, try the camera you're interested in to see if it really suits you.
