Comparison Canon EOS 800D body vs Canon EOS 80D 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 total number of individual light sensitive dots (pixels) provided in the camera's sensor. Denoted in megapixels - millions of pixels.

The total number of MPs, as a rule, is greater than the number of megapixels from which the frame is directly built (for more details, see "Effective number of MPs"). This is due to the presence of service areas on the matrix. In general, this parameter is more of a reference than practically significant: a larger total number of MPs with the same size and effective resolution means a slightly smaller size of each pixel, and, accordingly, an increased likelihood of noise (especially at high ISO values).

The number of pixels (megapixels) of the matrix directly involved in the construction of the image, in fact — the number of points from which the captured image is built. Some manufacturers, in addition to this parameter, also indicate the total number of MPs, taking into account the service areas of the matrix. However, it is the effective number of MPs that is considered the main indicator — it is this that directly affects the maximum resolution of the resulting image (see “Maximum image size”).

A megapixel is 1 million pixels. Numerous megapixels ensures high resolution of the captured photos, but is not a guarantee of high-quality images — much also depends on the size of the sensor, its light sensitivity (see the relevant glossary items), as well as hardware and software image processing tools used in the camera. Note that for small matrices, high resolution can sometimes be more of an evil than a blessing — such sensors are very prone to the appearance of noise in the image.

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 highest number of shots a camera can capture “in one go” in JPEG continuous shooting.

The technical features of modern digital cameras are such that during continuous shooting, photos have to be recorded in a special buffer, and only then, after the end of the series, they can be copied to a memory card. This buffer has a limited size, so the number of frames in one series is also limited. At the same time, we note that this indicator is usually indicated for shooting at the highest possible resolution (see "Maximum image size"); at lower resolutions, the volume of each image is reduced, and the number of frames in the series may turn out to be more than stated in the specifications.

JPEG, the most popular digital photography format today, is smaller and requires less processing power than RAW (see "Recording in RAW Format"). Therefore, in a JPEG series, as a rule, more frames are available to the photographer. However, in some models that have two separate buffers (for RAW and JPEG), it may be the other way around.

The highest number of shots the camera can capture “in one shot” when shooting in RAW format continuously (see “Recording in RAW Format”).

The technical features of modern digital cameras are such that during continuous shooting, photos have to be recorded in a special buffer, and only then, after the end of the series, they can be transferred to a memory card. This buffer has a limited size, so the number of frames in one series is also limited. At the same time, we note that this indicator is usually indicated for shooting at the highest possible resolution (see "Maximum image size"); at lower resolutions, the volume of each image is reduced, and the number of frames in the series may be more than stated in the specifications.

RAW images take up more space and require more processing power than "finished" JPEGs. Therefore, the number of frames in a series of this format is usually lower than that of JPEG. However, there are exceptions — usually these are cameras that have two separate buffers (for RAW and JPEG).

The number and / or types of scene programs for shooting videos provided in the design of the camera.

Scene programs are a set of presets designed for different shooting situations - for example, in sunlight, on a cloudy day, in a darkened room, etc. Also, this list may include other specific modes - for example, creative tools. In any case, the presence of scene programs facilitates the choice of video shooting parameters, which is very useful for novice users.

— USB C. A universal USB interface that uses a Type C connector. USB ports themselves (all types) are used mainly for connecting the camera to a computer for copying footage, managing settings, updating firmware, etc. Specifically The Type C connector is comparable in size to earlier miniUSB and microUSB, but has a reversible design that allows the plug to be inserted in either direction. In addition, USB C often operates according to the USB 3.1 standard, which allows for connection speeds of up to 10 Gbps - a useful feature when copying large amounts of content.

- HDMI. A comprehensive digital interface that allows you to transmit video (including high resolution) and audio (up to multi-channel) over a single cable. The presence of such a port makes it possible to use the camera as a player: it can be directly connected to a TV, monitor, projector, etc. and view your footage on the big screen. In this case, broadcast capabilities can include not only video playback, but also demonstration of captured photos in slide show mode. HDMI inputs are present in most modern video equipment, and connection is usually not a problem.
Nowadays, there are several versions of the HDMI interface on the market:

• v 1.4. The oldest version currently relevant, released in 2009. However, it supports 3D video, is capable of working with resolutions up to 4096x2160 at a speed of 24 fps, and in Full HD resolution the frame rate can reach 120...fps. In addition to the original v.1.4, there are also improved modifications - v.1.4a and v.1.4b; they are similar in basic capabilities, in both cases the improvements affected mainly work with 3D content.
• v2.0. Significant HDMI update introduced in 2013. In this version, the maximum frame rate in 4K has increased to 60 fps, and support for ultra-wide 21:9 format can also be mentioned. In update v.2.0a, HDR support was added to the interface capabilities; in v.2.0b this function was improved and expanded.
• v 2.1. Despite the similarity in name to v.2.0, this version, released in 2017, was a very large-scale update. In particular, it added support for 8K and even 10 K at speeds up to 120 fps, and also further expanded the capabilities for working with HDR. This version was released with its own cable - HDMI Ultra High Speed; all features of v.2.1 are available only when using cables of this standard, although basic functions can be used with simpler cords.

— Headphone output. Audio output allows you to connect headphones to the camera. As a rule, it is represented by a classic 3.5 mm mini-jack. The presence of such a connector provides the ability to monitor sound during video recording in real time. This is especially important when filming interviews, vlogs and other similar projects.

— Microphone input. Specialized input for connecting an external microphone to the camera. External microphones are significantly superior to built-in microphones in sound quality. Firstly, they are not so sensitive to the camera’s “own” sounds - from buttons, control wheels, focus motors, etc. (and if the microphone uses a long wire and is not attached to the body, these sounds will not be heard at all). Secondly, external microphones themselves have more advanced characteristics. On the other hand, their use is justified mainly for professional video recording; therefore, the presence of a microphone input, as a rule, corresponds to advanced video recording capabilities

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.).
