Comparison Canon EOS M200 kit 15-45 vs Canon EOS M50 kit 15-45

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.

Aperture of the lens installed in the camera or supplied with it in the kit (for models with detachable optics).

In a simplified way, this parameter can be described as the ability of the lens to transmit light - in other words, how much the light flux weakens when passing through the optics. It is believed that two main indicators affect the characteristics of light transmission: the size of the relative opening of the lens and its focal length. Aperture is the ratio of the first indicator to the second; in this case, the size of the active hole is taken as one and is generally omitted when recording, as a result, such a recording looks, for example, like this: f / 2.0. Accordingly, the larger the number after the fraction sign, the lower the aperture ratio, the less light the lens transmits.

Zoom lenses (zoom lenses), as a rule, have different aperture values for different focal lengths. For such optics, two values of this parameter are indicated in the characteristics, for the minimum and maximum focal lengths, for example, f / 2.8–4.5. There are also vario lenses that maintain a constant aperture over the entire range of focal lengths, but they are much more expensive than analogs with variable aperture.

The high light transmission of the lens is important if the camera is planned to be used for shooting in low light conditions or for shooting fast moving objects: high-aperture optics allow you to shoot at low sensor sensitivity (which...reduces the likelihood of noise) and at low shutter speeds (at which moving objects are less blurry) . This parameter also determines the depth of field of the imaged space: the higher the aperture ratio, the smaller the depth of field. Therefore, for shooting with artistic background blur (“bokeh”), it is recommended to use fast lenses.

— USB C. A universal USB interface that uses a Type C connector. USB ports themselves (all types) are used mainly for connecting the camera to a computer for copying footage, managing settings, updating firmware, etc. Specifically The Type C connector is comparable in size to earlier miniUSB and microUSB, but has a reversible design that allows the plug to be inserted in either direction. In addition, USB C often operates according to the USB 3.1 standard, which allows for connection speeds of up to 10 Gbps - a useful feature when copying large amounts of content.

- HDMI. A comprehensive digital interface that allows you to transmit video (including high resolution) and audio (up to multi-channel) over a single cable. The presence of such a port makes it possible to use the camera as a player: it can be directly connected to a TV, monitor, projector, etc. and view your footage on the big screen. In this case, broadcast capabilities can include not only video playback, but also demonstration of captured photos in slide show mode. HDMI inputs are present in most modern video equipment, and connection is usually not a problem.
Nowadays, there are several versions of the HDMI interface on the market:

• v 1.4. The oldest version currently relevant, released in 2009. However, it supports 3D video, is capable of working with resolutions up to 4096x2160 at a speed of 24 fps, and in Full HD resolution the frame rate can reach 120...fps. In addition to the original v.1.4, there are also improved modifications - v.1.4a and v.1.4b; they are similar in basic capabilities, in both cases the improvements affected mainly work with 3D content.
• v2.0. Significant HDMI update introduced in 2013. In this version, the maximum frame rate in 4K has increased to 60 fps, and support for ultra-wide 21:9 format can also be mentioned. In update v.2.0a, HDR support was added to the interface capabilities; in v.2.0b this function was improved and expanded.
• v 2.1. Despite the similarity in name to v.2.0, this version, released in 2017, was a very large-scale update. In particular, it added support for 8K and even 10 K at speeds up to 120 fps, and also further expanded the capabilities for working with HDR. This version was released with its own cable - HDMI Ultra High Speed; all features of v.2.1 are available only when using cables of this standard, although basic functions can be used with simpler cords.

— Headphone output. Audio output allows you to connect headphones to the camera. As a rule, it is represented by a classic 3.5 mm mini-jack. The presence of such a connector provides the ability to monitor sound during video recording in real time. This is especially important when filming interviews, vlogs and other similar projects.

— Microphone input. Specialized input for connecting an external microphone to the camera. External microphones are significantly superior to built-in microphones in sound quality. Firstly, they are not so sensitive to the camera’s “own” sounds - from buttons, control wheels, focus motors, etc. (and if the microphone uses a long wire and is not attached to the body, these sounds will not be heard at all). Secondly, external microphones themselves have more advanced characteristics. On the other hand, their use is justified mainly for professional video recording; therefore, the presence of a microphone input, as a rule, corresponds to advanced video recording capabilities

The type of viewfinder provided in the design of the camera.

A viewfinder is an eyepiece in which the photographer is able to see the image being shot, and in some cases additional information (the location of autofocus sensors, individual shooting parameters, etc.). Regardless of the type, viewfinders are useful in that they allow you to clearly see the image you are shooting, even in bright ambient light (which can cause displays to “blind”). Their disadvantages are the need to bring the camera close to the face, as well as the inconvenience when working with glasses (although the latter is partly offset by diopter correction in the viewfinder itself). The types of viewfinders can be as follows:

— Electronic. Such a viewfinder is a system of lenses with a small screen behind them. It is widely used in advanced cameras with non-replaceable lenses (see "Camera Type"), can be used in MILC cameras, and relatively recently full-fledged " SLRs " have appeared (in particular, made according to the so-called "translucent mirror technology") equipped with electronic viewfinders. The advantage of such a viewfinder is that, in addition to the image itself, it can display a large amount of service information (for example, about shooting parameters); the main disadvantage is the need to supply power from the battery (although the power consumption of such a system is still much lower than that of an...external display).

— Optical. In this case, an optical viewfinder means an independent system with its own eyepiece and lens, built into the camera body and directed parallel to the optical axis of the lens (mirror and prism systems are separated into separate categories). Such a system can be located both directly above the lens and in the corner of the body. The advantages of optical viewfinders are simplicity, low cost and compactness, due to the absence of a complex system of mirrors or prisms in the design. Such a viewfinder can be used in any non-reflex cameras (classic digital or MILC). The main disadvantage of this option is the mismatch between the position of its lens and the main lens of the camera (the so-called parallax effect); in most cases, this does not create inconvenience, but when shooting at close distances, you have to take an amendment (although there are camera models with viewfinders that automatically correct).

— Optical and electronic. A specific type of viewfinder that combines elements of both systems described above. Usually, such structures are based on an optical viewfinder, which provides for the possibility of projecting various service information onto a visible image. And in some models, the system can also be switched to a fully electronic mode, blocking the access of light through the optics and observing only the picture on the screen through the viewfinder.

— Optical (mirror). As the name implies, the design of such a viewfinder is based on a system of mirrors. Through this system, the real image perceived by the camera lens is fed into the viewfinder eyepiece (in other words, the photographer is actually looking directly through the lens). SLR viewfinders are used exclusively in cameras of the corresponding type (see above). Their advantages are the absence of the parallax effect and the ability to immediately evaluate a number of shooting parameters, such as depth of field, the effect of installed light filters, etc. The main disadvantage of reflex viewfinders is the need to raise the mirror at the time of shooting. This complicates and increases the cost of the design, makes it less reliable, and the operation of the mirror lifting mechanism can cause vibrations and the “stirring” effect.

— Optical (pentaprism). In fact, it is a kind of mirror viewfinder (see above), in which the role of a part of the mirrors is assigned to a pentaprism — a glass structure of a special shape. The action of the pentaprism is based on the effect of the so-called total internal reflection; it is believed that in this way it is possible to achieve a brighter and clearer image than when using classic mirrors. Other advantages and disadvantages are identical to conventional reflex viewfinders (see above). The pentaprism is widely used in mirror devices.

— Is absent. The complete absence of a viewfinder in the design of the camera; For sighting in such models, a display is used. This feature is typical mainly for digital compacts (see "Type of camera"). Firstly, the dimensions of the body of such models often do not allow for a viewfinder to be included in the design; secondly, the specifics of the use of such cameras is usually such that the display is quite enough for them, and sometimes it is even more preferable — for example, when shooting from a non-standard position (above your head, with your arm outstretched in front of you, etc.).

The ratio, expressed as a percentage, between the part of the image that the photographer sees in the viewfinder (see above) and the image actually captured by the camera when shooting. Most often it is specified as a percentage of the width and height of the frame, and not of the area.

Modern digital cameras quite often have viewfinders with a frame coverage of less than 100% - thus, not only the visible scene, but also some space beyond its edges gets into the frame. This creates some inconvenience - in particular, it may be necessary to crop the picture to ensure a pre-conceived composition. Therefore, a viewfinder with 100 percent coverage is still considered ideal. Some time ago, such systems were found mainly in premium cameras, but now, thanks to cheaper prices and advances in technology, they can be installed even in relatively inexpensive amateur compacts (see “Camera type”).

Continuous shooting speed provided by the camera at the maximum frame resolution. At lower resolutions, the speed may be higher, but this value is considered the key characteristic.

In continuous shooting, the photographer presses the button, and the camera takes several shots in a row, usually at intervals of a fraction of a second. Such shooting is convenient, for example, for capturing fast-moving objects: it allows you to choose the most successful from a series of frames, or to show the dynamics of movement using the entire series. And the higher the speed, the more effective the shooting, the more frames the camera can capture in a period of time. On the other hand, speed requires appropriate hardware and can significantly affect the cost.

- 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.
