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.
Total MP
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).
Maximum image size
The maximum size of photos taken by the camera in normal (non-panoramic) mode. In fact, this paragraph indicates the highest resolution of photography — in pixels vertically and horizontally, for example, 3000x4000. This indicator directly depends on the resolution of the matrix: the number of dots in the image cannot exceed the effective number of megapixels (see above). For example, for the same 3000x4000, the matrix must have an effective resolution of at least 3000*4000 = 12 million dots, that is, 12 MP.
Theoretically, the larger the size of the photo, the more detailed the image, the more small details can be conveyed on it. At the same time, the overall image quality (including the visibility of fine details) depends not only on resolution, but also on a number of other technical and software factors; see "Effective MP number" for more details.
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.
Kit lens
A lens supplied with the camera in a serial (kit) configuration. With it, the camera is ready to work literally “out of the box” - everything needed for shooting is already available, and there is no need to buy a lens separately (as is the case with the “naked body” of the
body camera). The vast majority of these are optics with a universal set of medium focal lengths and a relatively low variable aperture ratio. Often, kit lenses have rather modest characteristics, and they are intended mainly for novice users, learning the basics of photography and simple everyday shooting. But there are also other options
for whale lenses - top camera models can be equipped with fairly advanced optics. It wouldn’t hurt to clarify this point separately. We also note that the same camera can be supplied with different options for complete optics.
Full HD (1080)
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.
Ultra HD (4K)
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.
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.
Frame coverage
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").
