Comparison Canon EOS 200D kit 18-55 vs Canon EOS 100D kit 18-55

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 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.

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 number of scene programs provided in the camera design.

Scene programs are preset settings for some of the most common shooting scenes - for example, Portrait, Landscape, Sports, Sunset, etc. In addition to these presets, this list may include special effects and creative tools (such as color swap or fisheye), as well as exposure modes (see below). The presence of scene programs is especially useful for beginners and non-professional photographers, as it eliminates the need to tinker with each setting separately - just select the most suitable program, and all the necessary settings will be set automatically. The more scene programs the camera design provides, the wider its automatic adjustment capabilities.

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 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.
