Comparison Canon EOS RP body vs Canon EOS 6D Mark II body

— Digital compact. This term refers to the simplest variety of modern digital cameras — those that are often called "soap dishes" in everyday life. As the name implies, these models are small in size, so most of them can be carried even in your pocket. Other specific features include a small sensor (see "Sensor Size"), a fixed lens, and a high degree of automation — digital compacts with full manual shooting options are the exception rather than the rule. In general, this type of camera is designed mainly for amateur shooting — in most cases, the image quality is quite sufficient for domestic purposes, but such devices are usually unsuitable for professional photography.

— “Mirrorless” cameras MILC (Mirrorless Interchangeable Lens Camera — literally “mirrorless cameras with interchangeable lenses”) are compact cameras that are a kind of hybrid between compact digital cameras and “DSLRs”. They are not equipped with a system of mirrors, the viewfinder (if any) is made electronic or optical (see below), which allows you to minimize the weight and dimensions of the camera. On the other hand, such devices use matrices of the same class as in SLR cameras, which ensures high quality shooting with a minimum of noise. As the name suggests, MILC cameras also typically work with interchangeable lenses.

— Digital SLR cameras. The most technically advanced class of digital cameras. It got its name from the system of mirrors installed in the...camera body; thanks to these mirrors, light enters the viewfinder directly through the lens (and not through the auxiliary window, as on compact cameras). As a result, the photographer sees what will be shot in real time, with high-quality colour reproduction and high brightness. It is also important that the "SLR" matrix is closed from light most of the time — the light hits it only at the time of shooting, due to which it practically does not heat up and the noise in the resulting image is minimized. The lenses of such cameras are made interchangeable, and many settings, unlike conventional digital cameras, can be set manually.

— For a mobile phone. Cameras designed to be installed on a smartphone as an external accessory and not designed for stand-alone use. Outwardly, such a device resembles a lens with a mount on the phone case; however, inside this “lens” there is a full-fledged matrix, an image processor and a Wi-Fi or Bluetooth wireless module for connecting to a smartphone. The smartphone itself, when used, simultaneously plays the role of a screen and a control device, in addition, footage can be immediately transferred to it. Technically, a similar camera can be connected to another gadget — for example, a tablet: it's not a fact that it can be fixed on the case, but the connection itself is quite possible.

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 presence in the camera of a special mechanism for cleaning the matrix from dust and other contaminants.

This function is found only in models with interchangeable lenses — "reflex cameras" and MILC (see "Camera type"). When replacing the lens in such cameras, the sensor turns out to be open, and the probability of its contamination is quite high; and extraneous particles on the matrix, at best, lead to the appearance of extraneous artifacts, at worst, to damage to the sensor. To avoid this, cleaning systems are provided. They usually work on the principle of ultrasound: high-frequency vibration "resets" debris from the surface of the sensor.

Note that no cleaning system is perfect — in particular, such systems are “too tough” for condensate, salt deposits and other similar contaminants. So the matrix may still need manual cleaning (ideally, in a service centre). Nevertheless, this function allows you to effectively deal with at least dust, which greatly simplifies the life of the user.

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.

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 minimum distance from the camera lens to the object being shot, at which the lens is able to focus in the normal shooting mode (not with macro shooting, see "Macro shooting, about it").

The ability to manually (or automatically, according to predetermined parameters) change the exposure parameters during shooting, that is, the amount of light falling on the matrix. It is used when the automatically selected exposure parameters do not give a satisfactory result — for example, in difficult conditions, when the illumination of the main subject and the background is very different. The camera's exposure compensation capabilities are recorded in the format "± x EV, in y EV increments", such as "± 3 EV, in 1/2 EV increments". The first digit indicates the maximum amount by which the exposure can be changed from the original value by the compensation process; the second is the step (step) with which the change occurs. EV is a specific unit of measure for exposure; a 1 EV change in exposure means a 2x change in the amount of light hitting the sensor. An increase in EV indicates an increase in the amount of light due to opening the aperture or an increase in shutter speed, a decrease indicates the opposite. All modern cameras with exposure compensation function are capable of producing it “in both directions”.

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.

The number and / or types of scene programs for shooting videos provided in the design of the camera.

Scene programs are a set of presets designed for different shooting situations - for example, in sunlight, on a cloudy day, in a darkened room, etc. Also, this list may include other specific modes - for example, creative tools. In any case, the presence of scene programs facilitates the choice of video shooting parameters, which is very useful for novice users.
