Comparison Canon EOS 1300D kit 18-55 vs Nikon D3300 kit 18-55

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 physical size of the photosensitive element of a camera. Measured diagonally, often indicated in fractions of an inch — for example, 1/2.3" or 1/1.8" (accordingly, the second matrix will be larger than the first). Note that in such designations it is not the “ordinary” inch (2.54 cm) that is used, but the so-called "Vidiconovsky", which is less than a third and is about 17 mm. This is partly a tribute to the tradition that comes from television tubes — “vidicons” (the forerunners of modern matrices), partly a marketing ploy that gives buyers the impression that the matrices are larger than they actually are.

Anyway, at equal resolution (see Number of megapixels), a larger sensor size means a larger size of each individual pixel; accordingly, on large sensors, more light enters each pixel, which means that such sensors have a higher photosensitivity (see Light sensitivity) and a lower noise level, especially when shooting in low light conditions.

Most often in modern cameras there are such options:

— 1/2.3" and 1/1.7". Small matrices, typical for models without interchangeable lenses — compacts and digital ultrazooms(see "Camera type").

— 4/3. A kind of "transitional option" between small sensors of compact devices and large, but at the same time expensive "SLR" APS-C. The size of such a matri...x is 18x13.5 mm, which gives a diagonal of 22.5 mm (approximately 4/3 of the "Vidicon" inch described above, hence the name). It is used in SLR and "mirrorless" cameras (see "Camera type"), mainly entry-level, with Four Thirds and Micro Four Thirds mounts, respectively.

— APS-C. The size of matrices of this type can vary from 20.7x13.8 mm to 25.1x16.7 mm, depending on the manufacturer. They are widely used in entry-level and mid-level SLRs, as well as "mirrorless" models.

— APS-H. Somewhat larger than the APS-C described above (the size is 28.1x18.7 mm), otherwise it is almost completely the same.

— Full frame (or APS). The size of such a matrix is equal to the frame size of a classic photographic film — 36x24 mm. It is usually equipped with professional-grade SLR cameras.

— Big frame. This category includes all types of matrices, the size of which exceeds 36x24 mm (full frame). Cameras with similar sensors belong to the so-called medium format class and are, usually, professional models of the premium level. Large matrices allow you to use a resolution of tens of megapixels, while maintaining high clarity and colour quality, however, such devices cost accordingly.

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.

No AA filter in camera design.

The AA filter is responsible for "anti-aliasing" — the elimination of the moiré effect. This effect can occur when shooting objects with a lot of thin horizontal or near-horizontal lines (for example, a brick wall at a great distance, or a suit made of a certain type of fabric). It leads to the appearance of a characteristic pattern in the picture, which, usually, is inappropriate; to eliminate this phenomenon, an AA filter is provided. At the same time, this feature is said to reduce the overall sharpness of the image; therefore, it may not be available in some cameras. These are mainly professional models: the absence of an AA filter gives the photographer additional features, but puts forward increased requirements for shooting skills.

The type of bayonet mount — mount for interchangeable lenses — provided in a SLR or MILC camera (see "Camera type"). Bayonets come in different sizes, and interchangeable lens specifications usually indicate which mount it is designed for. Most often, mounts of different types are not compatible with each other, but there are exceptions (sometimes directly, sometimes using adapters).

Also note that one brand can use different mounts for different classes of cameras — and vice versa, one mount can be used by several manufacturers. So, Canon releases cameras with mounts EF-M, EF-S, EF and Canon RF. Leica has Leica M, Leica SL, Leica TL. Nikon has in its arsenal Nikon 1, Nikon F, Nikon Z. Pentax — Pentax 645, Pentax K, Pentax Q. Samsung offers NX and NX-M mounts. Sony cameras have Sony A and Sony E, Fuji has Fujifilm G and Fujifilm X. And as an example of a mount used by different brands, one can cit...e Micro 4/3, which is widespread in Olympus and Panasonic cameras.

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.
