DxOMark rating

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.

Light sensitivity (ISO)

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.

Image stabilization

An image stabilization method provided by a camera. Note that optical and sensor-shift systems are sometimes combined under the term "true" stabilization, due to their effectiveness. See below for more details.

Stabilization itself (regardless of the operating principle) allows you to compensate for the "shake" effect when the camera is not positioned correctly - especially when shooting handheld. This is especially important when shooting with significant magnification or at long shutter speeds. However, in any case, this function reduces the risk of ruining the frame, so cameras with stabilization are extremely common. The operating principles can be as follows:

— Electronic. Stabilization is carried out by means of a kind of “reserve” — a section along the edges of the sensor, which is not initially involved in the formation of the final image. However, if the camera electronics detect vibrations, it compensates for them by selecting the necessary fragments of the image from the reserve. Electronic systems are extremely simple, compact, reliable and at the same time inexpensive. However, for their operation, it is necessary to allocate a fairly significant part of the sensor — and reducing the useful area of the sensor increases the noise level and degrades the image quality. And in some models, electronic stabilization is enabled only at lower resolutions and is not available at full...frame size. Therefore, in its pure form, this option is found mainly in relatively inexpensive cameras with non-replaceable optics.

— Optical. Stabilization is achieved when light passes through the lens — due to a system of moving lenses and gyroscopes. As a result, the image gets to the sensor already stabilized, and the entire area of the sensor can be used for it. Therefore, optical systems, despite their complexity and rather high cost, are considered more preferable for high-quality shooting than electronic ones. Separately, we note that in SLR and MILC cameras (see "Camera type") the presence of this function depends on the installed lens; therefore, for such models, optical stabilization is not indicated in our catalog in principle (even if the kit lens is equipped with a stabilizer).

— With sensor shift. Stabilization performed by shifting the sensor "following" the shifted image. Like the optical one described above, it is considered a fairly advanced option, although in general it is somewhat less effective. On the other hand, sensor shift systems have serious advantages — first of all, such stabilization will work regardless of the characteristics of the lens. For cameras with non-replaceable optics, this means that the lens can do without an optical stabilizer and make the optics simpler, cheaper and more reliable. In SLR and MILC cameras, sensor shift allows even "non-stabilized" lenses to be used with convenience, and when "stabilized" optics are installed, both systems work together, and their efficiency is very high. In addition, sensor shift is somewhat simpler and cheaper than traditional optical stabilizers.

— Optical and electronic. Stabilization that combines both of the above options: initially, it operates on an optical principle, and when the lens's capabilities are not enough, an electronic system is connected. This allows for an increase in overall efficiency in comparison with purely optical or purely electronic stabilizers. On the other hand, the disadvantages of both options in such systems are also combined: the optics are comparatively complex and expensive, and not the entire sensor is used. Therefore, such a combination is rare, mainly in individual advanced digital compacts.

— With sensor shift and electronic. Another type of combined stabilization systems. Like "optical + electronic", it improves the overall efficiency of stabilization, but at the same time combines the disadvantages of both methods (they are also similar: more complicated and more expensive camera plus a decrease in the useful area of the sensor). Therefore, this option is used extremely rarely - in single models of digital ultrazooms and advanced compacts.

File recording formats

File formats in which the camera can record video. Given that the footage is designed to be viewed on an external screen, you should make sure that the playback device (DVD player, media centre, etc.) is able to work with the appropriate formats. At the same time, many camera models themselves can play the role of a player by connecting to a TV via an audio / video output or HDMI (see the corresponding paragraphs of the glossary). And if the video materials are to be viewed on a computer, you should not pay special attention to this parameter at all: problems with format incompatibility in such cases rarely occur, but are usually solved by installing the appropriate codec.

Connection ports

— 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

Autofocus modes

Autofocus operating modes provided in the camera design.

— One picture. The main mode of autofocus operation is found in all modern cameras and is used most often. Designed for shooting motionless objects.

— Follower. This mode is used for shooting moving objects, the distance to which is constantly changing: the camera constantly monitors the position of the object, constantly adjusting the optics so that it is in focus. Usually found in middle and upper class cells.

— AI focus. A peculiar combination of the previous two modes is used when a stationary object can start moving at any moment. If the scene is static, autofocus works in the single frame mode, but if the object on which focus is made starts to move, the device switches to tracking autofocus mode. AI mode allows you to almost instantly set the optimal autofocus settings, which is especially useful for sequential shooting. Initially, it was found in expensive models, however, thanks to the development of technology, today it can even be used in inexpensive compacts (see “Camera type”).

— By the face. Autofocus mode that uses a face recognition system and focuses on them. This feature is especially useful for taking pictures of people at a great distance from the camera, when the face is much smaller than the frame size, such as in group shots.

— With a smile. A further development of the face autofocus mode described above, when, in accordance with the nam...e, the system reacts not just to a face, but to a smile. This mode can be combined with the function of automatic shooting at the moment of a smile.

— Animal in the frame. A mode designed primarily for shooting animals, which can be difficult (and often impossible) to make them sit still in the frame. It is usually a variation of the tracking autofocus described above, but specific features of operation may vary depending on the camera model.

This list is not exhaustive, and other specific autofocus modes may be provided in the design of modern cameras.

Touch focus

The presence of the touch focus function in the design of the camera.

Such focus is necessarily combined with a touch screen (see below). It gives the photographer the opportunity to independently choose a point for focus in the frame being shot: for this, it is enough to touch this point on the image displayed on the screen. Touch focus is extremely simple and intuitive, and therefore very convenient, especially for beginners and non-professional users.

Viewfinder crop

This setting can be simplistically described as the amount of magnification provided by the viewfinder relative to how the image appears to the naked eye. The features of modern viewfinders are such that most of them have crop values less than 1 — that is, it somewhat reduces the visible “picture”.

In general, the larger this parameter, the larger the objects look in the viewfinder and the easier it is to focus through it.

Shutter type

The shutter is a system that regulates the duration of exposure, that is, the effect of light on the matrix (for more details on exposure, see above). Here are the main types of such systems:

Electronic. A type of shutter that is only suitable for digital cameras. Such systems do not have moving mechanical parts; exposure in them is carried out electronically. At the moment the shutter is pressed, when the shutter is “opened”, the matrix is completely reset; and after a certain time (corresponding to the exposure time), when the shutter is “closing”, the accumulated charge is read from it. This allows you to carry out full-fledged photography and work with different shutter speeds without using complex structures. Another advantage over the mechanical shutters described below is that such systems are perfect for Live View (see above): the matrix can constantly broadcast the image on the screen, only sometimes “interrupting” directly into shooting. On the other hand, such a constant work increases the likelihood of heating and the appearance of additional noise in the picture. To compensate for this shortcoming, various solutions are used, and in most cases it is almost invisible; however, for professional photography, electronic shutters are still considered less suitable than mechanical shutters.

Mechanical. There are many types of mechanical shutters, however, in modern digital c...ameras, systems in the form of a pair of shutters are predominantly found. When the shutter opens, one of the curtains moves, and then the second “catches up” with it, closing the matrix. The main advantage of mechanical shutters is that when using them, the matrix always remains closed and opens only at the moment of shooting for a time corresponding to the set shutter speed (similar to how it happens in film cameras). Due to this, it is possible to avoid heating the sensor and the associated increase in image noise. On the other hand, additional mechanisms noticeably affect the weight, dimensions, cost and power consumption of the camera; when shooting fast moving objects, distortions may occur, and at low temperatures — failures and even failures. In addition, cameras with mechanical shutters are mainly designed to work through an optical viewfinder. For an electronic viewfinder or Live View mode (see above), you either need to install an auxiliary matrix (which further complicates and increases the cost of the design), or completely open the shutters and actually shoot in electronic shutter mode, which makes the very idea of \u200b\u200b"mechanics" meaningless. As a result, this type of shutter is currently used mainly in SLR cameras (see "Camera type") of the middle and top levels; it is also found in other varieties, but much less frequently.

— Electronic/mechanical. Systems that combine both options described above; more precisely, even — mechanical shutters, supplemented by the ability to work in electronic mode. One of the key disadvantages of purely mechanical systems is their poor suitability for ultra-short shutter speeds — it is not easy to provide the necessary shutter speed, and besides, the mechanism is subjected to significant loads in this mode. To eliminate this shortcoming, electronic-mechanical systems were created. They work as follows: at short shutter speeds, a purely mechanical method of operation is used up to a certain limit, and when the possibilities of mechanics are not enough, a combined mode is used. In this mode, the shutter curtains open for a relatively long time (longer than the required shutter speed), while the matrix works electronically (see above for more details), providing the required shutter speed. Theoretically, the combined method allows you to effectively shoot at ultra-low shutter speeds, but in fact the quality of the images is relatively low, and the “hybrid” shutter is often more of a marketing ploy than a really useful tool.
