Comparison Sony A6600 body vs Sony A6100 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.

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

By itself, stabilization (regardless of the principle of operation) allows you to compensate for the effect of "shake" with an unstable camera position - especially when shooting handheld. This is especially true when shooting with a significant increase or at slow shutter speeds. However, in any case, this function reduces the risk of spoiling the frame, so cameras with stabilization are extremely common. The principles of work can be as follows:

— Electronic. Stabilization, carried out due to a kind of "reserve" - a section along the edges of the sensor, which initially does not participate in the formation of the final image. However, if the camera electronics detect fluctuations, it compensates for them by selecting the necessary image fragments from the reserve. Electronic systems are extremely simple, compact, reliable and at the same time inexpensive. However, for their work it is necessary to allocate a fairly significant part of the sensor - and reducing the usable area of the sensor increases the noise level and degrades the image quality. And in some models, electronic stabilization is turned on only at lower resolutions and is not available at ful...l frame size. Therefore, in its pure form, this option is found mainly in relatively inexpensive cameras with non-replaceable lenses.

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

- With sensor shift. Stabilization, carried out 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, systems with a sensor shift have serious advantages - first of all, the fact that such stabilization will work regardless of the characteristics of the lens. For cameras with fixed lenses, 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, the sensor shift makes it possible to use even “non-stabilized” lenses with convenience, and when installing “stabilized” optics, 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 options described above: initially it operates according to the optical principle, and when the capabilities of the lens are not enough, an electronic system is connected. This improves the overall efficiency compared to purely optical or purely electronic stabilizers. On the other hand, the disadvantages of both options in such systems are also combined: the optics are relatively complex and expensive, and not all of the sensor is involved. Therefore, such a combination is rare, mainly in separate advanced digital compacts.

- With sensor shift and electronic. Another type of combined stabilization systems. Like “optical + electronic”, it improves the overall stabilization efficiency, but at the same time it combines the disadvantages of the two methods (they are also similar: the complication and rise in price of the camera, plus a decrease in the useful area of \u200b\u200bthe sensor). Therefore, this option is used extremely rarely - in single models of digital ultrazooms and advanced compacts.

The maximum resolution and frame rate of video captured by the camera in Full HD (1080p).

The traditional Full HD video resolution in this case is 1920x1080; other options are more specific and practically do not occur in modern cameras. 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.

— 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

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.

The presence of a built-in flash in the design of the camera. The meaning of this function is generally obvious: in situations where a flash is needed (for example, in low light or backlit conditions), it allows you to do without external accessories. On the other hand, the power of built-in flashes is usually very low, and many of the features implemented in external equipment are not available for built-in flashes (for example, the lamp cannot be turned up to provide diffused light). Therefore, in more or less advanced cameras, this function, usually, is combined with the ability to install an external flash (see below), and in professional models, a built-in lamp is often absent altogether.

The minimum/maximum distance from the subject to the lens at which the flash can be used effectively (usually limited to a few metres). Since lenses with a variable focal length have different aperture ratios depending on the set focal length (see Aperture), for cameras with such optics, two ranges of flash application are indicated — for the minimum and maximum focal lengths, for example "0.3 — 3.5 (W), 0.45 — 2(T)." The letters W and T in such markings indicate the minimum and maximum focal lengths, respectively.

The model name of the original battery (see "Power Type") used in the camera. Knowing this name, you can easily find a spare or replacement battery for the device.
