Comparison Sony A6100 body vs Sony A6300 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 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.

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.

Restrictions on the length of the recorded video provided in the design of the camera. In some models, the recording time is limited in time (for example, 30 minutes) — thus, to record a longer video, it will have to be split into separate clips. In others, the duration depends only on the amount of free memory — you can record as long as there is enough space. There is also a combination of these options; in such models, video recording stops as soon as either of the two limits is reached.

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.

- GPS module. The camera has a built-in GPS satellite navigation module. In digital cameras, the GPS module is used primarily for setting the so-called. geo-tagging to photos: information about specific geographical coordinates of the shooting location is recorded in the service information about each image. However, the matter is not limited to this, and models with this function can have many additional features - from classic navigation to special programs like a database of points of interest with hints based on the current location.

- WiFi. A wireless standard originally developed for computer networking, but more recently allowing for direct connection between devices. The ways in which Wi-Fi is used in cameras can vary. Thus, the most popular option is to connect to a smartphone, tablet or other similar device for remote control (see below) and / or transfer footage to an external device. Some cameras have built-in software that allows you to directly connect to the Internet through wireless access points and upload photos and videos to popular network services. And in models running Android (see above), specific features depend only on the installed software and may include full access to social networks through client programs (see below) and even web surfing through a browser.

— Bluetooth. A wireless interface used to communicate with various electronic devices. In cameras, Blu...etooth is most often used to connect to a computer or laptop and transfer footage; In addition, it allows you to use the direct printing function on printers equipped with Bluetooth. The range of Bluetooth communication is up to 10 m, and the devices do not necessarily have to be in direct line of sight to each other.

- NFC chip. NFC (Near-Field Communication) is a wireless communication technology designed to connect various portable devices with each other at a distance of up to several centimeters. In cameras it plays an auxiliary role, designed to facilitate connection with other devices (smartphones, tablets, etc.) using a longer-range standard (Wi-Fi or Bluetooth). Instead of delving into the settings - looking for devices, connecting them manually - just bring the NFC camera to a gadget equipped with the same chip and confirm the connection request.

— Control from a smartphone. The ability to remotely control the camera using a smartphone, tablet or other similar gadget. The connection between the camera and the control device is usually carried out via Wi-Fi (see above), while a special application is used for control, and the gadget’s screen plays the role of a viewfinder. The specific capabilities of such control can be different - releasing the shutter on command, selecting exposure parameters and other shooting settings, focusing by touch, etc. Often, it is also possible to “drain” the footage onto the control device and, through it, to the Internet. Note that for cameras used with mobile phones (see “Camera Type”), this function is not indicated: such a camera is usually mounted directly on the device, and there is no talk of remote control.

The maximum number of photos that the camera can take on a single battery without recharging/replacing it. In fact, this number usually turns out to be less (sometimes quite noticeable) due to the fact that part of the charge is “eaten up” by the lens mechanics, using the display, changing settings through the menu, etc. Nevertheless, this parameter is a good indicator of the battery life of the device, and different models can be compared with each other.
