Comparison Canon EOS M50 body vs Canon EOS M6 body

The result shown by the camera in the DxOMark ranking.

DxOMark is one of the most popular and respected resources for expert camera testing. According to the test results, the camera receives a certain number of points; The more points, the higher the final score.

The sensitivity range of a digital camera matrix. In digital photography, light sensitivity is expressed in the same ISO units as in film photography; however, unlike film, the light sensitivity of the sensor in a digital camera can be changed, which gives you more options for adjusting shooting parameters. High maximum light sensitivity is important if you have to use a lens with a low aperture (see Aperture), as well as when shooting dimly lit scenes and fast-moving objects; in the latter case, high ISO allows you to use low shutter speeds, which minimizes image blur. However, note that with an increase in the value of the applied ISO, the level of noise in the resulting images also increases.

The presence of two control dials in the design of the camera.

This design feature makes it easier to control the camera and change settings on the fly: additional operating parameters are transferred to the second disk, and turning it to the desired position is easier and faster than “digging” in the on-screen menu items. This feature is found mainly in semi-professional and professional cameras, which involve frequent use of manual shooting mode.

Bracketing is called shooting a series of frames, in which in each next frame the shooting parameters (exposure, white balance, focus, etc.) change by a certain amount. This allows, for example, to choose the most successful shot from several options, or to determine the effect of changing the settings in one direction or another. Auto bracketing allows you to take such shots automatically. At the same time, it should be taken into account that the set of parameters changed in the process may differ in different camera models. For example, some devices are able to change only the exposure, others — the exposure and/or white balance, etc.

The maximum resolution and frame rate of video captured by the camera in the Ultra HD (4K) standard.

UHD 4K refers to resolutions with a frame size of approximately 4,000 horizontal pixels. Specifically, in cameras for video shooting, resolutions of 3840x2160 and 4096x2160 are most often used. Regarding the frame rate, it is worth noting first of all that a normal (not slow-motion) video is shot at a speed of up to 60 fps, and in this case, the higher the frame rate, the smoother the video will be, the less jerks will be noticeable when moving in the frame. If the frame rate is 100 fps or higher, this usually means that the camera has a slow-motion video mode.

The number of focus points (autofocus) provided in the design of the camera.

The focus point is the point (more precisely, a small area) in the frame from which the autofocus system reads data for focusing. The simplest systems work with a single point, but their capabilities are very limited, and this option is practically not found today. Modern digital cameras have at least three focus sensors, and in the most advanced models this figure can reach several dozen.

The more autofocus sensors there are in the camera, the more advanced its autofocus capabilities will be, the more specific techniques it allows you to use. In this case, the selection of specific points used can be carried out both automatically, simultaneously with the choice of the subject program, and manually (however, the second option is more typical for professional cameras). In addition, the abundance of focus points has a positive effect on the quality of the tracking autofocus (see "Autofocus Modes").

In general, more focus sensors are generally considered a sign of a more advanced camera; however, differences in quality become really noticeable only if the difference in the number of points is significant - for example, if we compare models with 9 and 39 points. A lot also depends on the location of the points in the frame - it is believed that sensors distributed over a wide area work better than densely located in the center of the frame, even if their number is the same.

The type of viewfinder provided in the design of the camera.

A viewfinder is an eyepiece in which the photographer is able to see the image being shot, and in some cases additional information (the location of autofocus sensors, individual shooting parameters, etc.). Regardless of the type, viewfinders are useful in that they allow you to clearly see the image you are shooting, even in bright ambient light (which can cause displays to “blind”). Their disadvantages are the need to bring the camera close to the face, as well as the inconvenience when working with glasses (although the latter is partly offset by diopter correction in the viewfinder itself). The types of viewfinders can be as follows:

— Electronic. Such a viewfinder is a system of lenses with a small screen behind them. It is widely used in advanced cameras with non-replaceable lenses (see "Camera Type"), can be used in MILC cameras, and relatively recently full-fledged " SLRs " have appeared (in particular, made according to the so-called "translucent mirror technology") equipped with electronic viewfinders. The advantage of such a viewfinder is that, in addition to the image itself, it can display a large amount of service information (for example, about shooting parameters); the main disadvantage is the need to supply power from the battery (although the power consumption of such a system is still much lower than that of an...external display).

— Optical. In this case, an optical viewfinder means an independent system with its own eyepiece and lens, built into the camera body and directed parallel to the optical axis of the lens (mirror and prism systems are separated into separate categories). Such a system can be located both directly above the lens and in the corner of the body. The advantages of optical viewfinders are simplicity, low cost and compactness, due to the absence of a complex system of mirrors or prisms in the design. Such a viewfinder can be used in any non-reflex cameras (classic digital or MILC). The main disadvantage of this option is the mismatch between the position of its lens and the main lens of the camera (the so-called parallax effect); in most cases, this does not create inconvenience, but when shooting at close distances, you have to take an amendment (although there are camera models with viewfinders that automatically correct).

— Optical and electronic. A specific type of viewfinder that combines elements of both systems described above. Usually, such structures are based on an optical viewfinder, which provides for the possibility of projecting various service information onto a visible image. And in some models, the system can also be switched to a fully electronic mode, blocking the access of light through the optics and observing only the picture on the screen through the viewfinder.

— Optical (mirror). As the name implies, the design of such a viewfinder is based on a system of mirrors. Through this system, the real image perceived by the camera lens is fed into the viewfinder eyepiece (in other words, the photographer is actually looking directly through the lens). SLR viewfinders are used exclusively in cameras of the corresponding type (see above). Their advantages are the absence of the parallax effect and the ability to immediately evaluate a number of shooting parameters, such as depth of field, the effect of installed light filters, etc. The main disadvantage of reflex viewfinders is the need to raise the mirror at the time of shooting. This complicates and increases the cost of the design, makes it less reliable, and the operation of the mirror lifting mechanism can cause vibrations and the “stirring” effect.

— Optical (pentaprism). In fact, it is a kind of mirror viewfinder (see above), in which the role of a part of the mirrors is assigned to a pentaprism — a glass structure of a special shape. The action of the pentaprism is based on the effect of the so-called total internal reflection; it is believed that in this way it is possible to achieve a brighter and clearer image than when using classic mirrors. Other advantages and disadvantages are identical to conventional reflex viewfinders (see above). The pentaprism is widely used in mirror devices.

— Is absent. The complete absence of a viewfinder in the design of the camera; For sighting in such models, a display is used. This feature is typical mainly for digital compacts (see "Type of camera"). Firstly, the dimensions of the body of such models often do not allow for a viewfinder to be included in the design; secondly, the specifics of the use of such cameras is usually such that the display is quite enough for them, and sometimes it is even more preferable — for example, when shooting from a non-standard position (above your head, with your arm outstretched in front of you, etc.).

The ratio, expressed as a percentage, between the portion of the image that the photographer sees in the viewfinder (see above) and the image that is actually captured by the camera when shooting. Most often, it is specified as a percentage of the width and height of the frame, rather than the area.

Modern digital cameras often have viewfinders with a frame coverage of less than 100% - thus, the frame includes not only the visible scene, but also some space beyond its edges. This creates some inconveniences - in particular, it may be necessary to crop the photo to ensure a pre-conceived composition. Therefore, a viewfinder with 100% coverage is still considered the ideal option. Some time ago, such systems were found mainly in premium cameras, but now, thanks to cheaper prices and technological developments, they can be installed even in relatively inexpensive amateur compacts (see "Product type").

Continuous shooting speed provided by the camera at the maximum frame resolution. At lower resolutions, the speed may be higher, but this value is considered the key characteristic.

In continuous shooting, the photographer presses the button, and the camera takes several shots in a row, usually at intervals of a fraction of a second. Such shooting is convenient, for example, for capturing fast-moving objects: it allows you to choose the most successful from a series of frames, or to show the dynamics of movement using the entire series. And the higher the speed, the more effective the shooting, the more frames the camera can capture in a period of time. On the other hand, speed requires appropriate hardware and can significantly affect the cost.
