Comparison Canon LEGRIA HF G26 vs Canon LEGRIA HF G40

— Amateur. As the name implies, these cameras are designed for relatively simple tasks and normal everyday use — filming family chronicles, solemn events, small documentaries, video presentations, etc. Note that amateur devices can have a fairly wide range of settings and provide high image quality. However, even the most advanced options cannot replace professional equipment; and the general principle of their design is to simplify and facilitate operations. One of the characteristic features of this type of camera is its compact size (although larger than that of the pocket cameras described below), which make it easy to hold the device in one hand. In addition, models with a viewfinder are very rare among them (see "Features"), and models with an interchangeable lens (see below) are not found at all.

— Professional. Cameras designed for professional shooting are outwardly distinguished by their large size — they are noticeably larger than amateur ones, and are often designed to be carried on the shoulder, and not held in hands (although there are compact models comparable to amateur ones). This is primarily due to the abundance of features: models of this type have many additional settings, each of them can be controlled manually, as well as an extended set of interfaces, more capacious batteries, mounts for external microphones, etc. It is also worth not...ing the presence of the devices with interchangeable lenses (see below) in this class . Professional cameras are excellent for TV journalism and filming, but they are poorly suited for personal use. And the point here is not only in large size and high cost: handling such a device requires certain skills, and an abundance of settings can create many problems for inexperienced users.

— 3D camcorder. This category includes all models that have the 3D feature (see below). The specific appearance and functionality of such cameras may vary: some are closer to the amateur models described above, others are closer to professional ones. The same applies to the implementation of 3D: some models are initially equipped with a stereo lens, in others this feature is performed with an adapter mounted on traditional "two-dimensional" optics.

— Pocket. This type can be described as a specific kind of amateur camera, designed for maximum compactness (including, in fact, the possibility of carrying in your pocket). Some pocket models are similar in appearance to the "shrunken to the limit" versions of full-size cameras, others resemble mobile phones with a specific placement of the lens — on the back cover. Anyway, such cameras are extremely convenient to carry and they allow you to always have a recording device at hand, the capabilities of which are significantly superior to those of phones. On the other hand, for the sake of portability, you usually have to sacrifice many specifications — the capabilities of optics, the size of the sensor, etc. — because of this the capabilities of pocket cameras are significantly lower than even amateur ones, not to mention professional ones.

Aperture of a standard video camera lens.

This parameter describes how much the lens attenuates the light output. Usually it is written as a ratio between the diameter of the active hole and the focal length of the lens, while the first value is taken as one and denoted as f — for example, f/1.8 or f/5.6. Moreover, the smaller the number in such a record, the higher the aperture ratio: for example, in our example, the first option is “lighter” than the second. Also note that most lenses with a variable focal length (see above) also have a variable aperture — in such cases it is indicated by the range from maximum to minimum (from a smaller number to a larger one).

A high aperture ratio is important primarily when shooting in low light conditions: it allows you to capture an image without “lifting up” the sensor sensitivity and without creating additional artifacts in the form of noise, and in the photo shooting mode, you can also work with shorter shutter speeds (which is useful for dynamic scenes). In addition, the higher the aperture, the lower the depth of field and the easier it is to get a blurry background. Note that for simple everyday tasks this parameter does not play a decisive role, but in professional shooting it can be very significant.

Video file formats that the camera can use to store recorded footage. If you want to view these materials using a separate device (player, media centre, etc.), you should make sure that this player supports the appropriate formats, otherwise conversion may be necessary.

The range of shutter speeds in which the camera is capable of operating during the shooting process.

Initially, shutter speed is the time during which light affects the photosensitive material (film) when shooting a single frame. For digital sensors, this is the period of time during which an image is read from the sensor to build a separate frame. When shooting video, this interval cannot be more than 1/n, where n is the frame rate (see above), but it can be less — for example, shooting at a frame rate of 30 fps and shutter speed of each frame 1/60 s. There are no such restrictions for the photo mode.

Long exposures are good because they allow the sensor to take in more light — accordingly, the “picture” is brighter, which is especially important in low light. At the same time, they increase the likelihood of getting a blurry image — due to the rapid movement of objects in the frame, the operator's hand shaking and other random camera movements that even the stabilization system is unable to compensate for. This effect can be useful for artistic motion blur, especially when shooting video, but in photo mode it is most often undesirable. Fast shutter speeds, on the other hand, allow you to get clear shots, but with less light, and in the case of video, even with the effect of sharp, jerky movements.

Accordingly, different exposure time options will be optimal for each situation, and the wider their range, the more opportunities the came...ra has to adjust to specific conditions.

Diagonal size of the camcorder's own display in inches. The larger the display, the larger the image on it will be, the easier it will be to work with the screen both during the shooting process and when viewing the footage. On the other hand, a large screen has an effect on the size of the camera itself, you don’t need large sizes to work with a frame, and it’s more convenient to view the footage on a full-sized device like a TV. With this in mind, most modern models are equipped with displays with a diagonal of about 2 – 3.5"; larger screens are extremely rare — even in professional cameras (see "Features"), for which compactness is not a priority.

— Viewfinder. The presence of a viewfinder in the design of the camera — a special optical device in the form of a tube with an eyepiece and a small screen under it. Actually, the role of this device is similar to a conventional display: pointing the frame, controlling the shooting parameters, viewing the footage. The main difference is that in this case the screen is maximally covered and its visibility is almost independent of the ambient light conditions; this is very important in bright sunlight and in other similar situations where outdoor displays "become blind". In addition, the viewfinder can also be useful when stealth is important — it does not reflect on the operator's face and does not unmask it; and such systems consume less energy. On the other hand, the eyepiece during operation must be brought close to the eye; and if the external display allows you to hold the camera, for example, at arm's length above your head, then the viewfinder does not provide such freedom for manoeuvre. Also shooting through such a device can be quite tedious, especially for unaccustomed users; and viewfinders are poorly compatible with glasses. As a result, this element is found mainly in professional models of cameras (see "Features").

— Built-in flash. The presence of a flash in the camera — a light source for taking photos. The most popular use of a flash is to provide illumination in low light condit...ions; in addition, it can be used for shooting opposite to a bright light and some other special tasks. In cameras equipped with a backlight (see below), the same lamp can also act as a flash.

— Backlight lamp. The presence of its own lamp to illuminate insufficiently lit scenes in the design of the camera. This lamp differs from the flash described above as it is designed to work during video shooting and operates in constant light mode, and not in impulses. Backlight allows you to use the camera autonomously, without external lighting devices, which can not always be installed. However, do not forget that its operation also consumes battery power.

— Hot shoe. Hot shoe is a specialized mount for installing additional accessories. Most often it is used for external flashes, but not only: external viewfinders, microphones, GPS modules and much more can be attached to the hot shoe. There are several generally accepted standards for this mount, in addition, each manufacturer uses its own set of additional contacts to control advanced features of external equipment; this must be taken into account when selecting such equipment. However, if you intend to use external accessories, it makes sense to choose a camera with a hot shoe. Most of these models are professional (see "Features"), but there are exceptions.

— Built-in speaker. The presence of its own speaker in the camera design. This feature allows you to view footage with sound without the need for additional equipment such as headphones. Note that the quality of the built-in speakers is usually low, and they are not designed for more serious tasks (for example, playing music); and when viewing, they allow not so much to evaluate the quality of the audio, but to determine whether the sound was recorded.

— Built-in projector. The presence of its own projector in the camera design. This feature greatly simplifies the viewing of footage: it allows to provide a fairly large "picture" (with a diagonal of several tens of centimeters) using the camera itself, without the use of TVs or other external screens. However for viewing you will need a suitable surface — at least a plain light wall; but the power of the projectors themselves is low, and in bright light the image may not be visible at all. However, if the video needs to be shown to several viewers at once, this option is definitely more convenient than viewing it on the camera's own screen. In addition, you can watch any video uploaded to memory of a suitable format on the projector — in other words, use the camera as a player.

— Wi-Fi module. The camera has its own Wi-Fi wireless module. This standard is used to build computer networks, and more recently – also for direct communication between various devices: laptops, smartphones, tablets, etc. Specific options for using Wi-Fi may vary depending on the camera model, and include options such as direct copying of content to an external device or even to the Internet (such as YouTube), remote control of the camera, use as a webcam (see below). below), firmware update, etc. And all this is carried out without the use of wires, the communication range can reach 100 m, and the walls are not an obstacle (although they reduce the "range").

— NFC. The presence of a chip for NFC standard wireless communication in the camera. The range of such communication is up to 10 cm, and in cameras it plays an auxiliary role, facilitating the wireless connection of the camera and an external device (smartphone, tablet, etc.) that also has an NFC. Instead of digging through the settings, just bring both devices close to each other and confirm the Wi-Fi connection (see above). Accordingly, this chip is installed only in cameras that have more wireless capabilities.

— GPS module. The camera has a built-in GPS satellite navigation module. By itself, such a module during operation only captures the current location based on data from satellites, but how this data is used depends on the specific camera model. Most often, devices with GPS are able to at least add geotags to the footage — information about the geographical coordinates of the shooting location; but besides this, more extensive features can be provided — for example, search among the materials at the location of the shooting or even full-fledged navigation on the map.

— Detachable microphone. The presence of a mount in the design of the camera for installing an external removable microphone; the microphone itself can be included in the package or purchased separately. This function is typical for professional models and 3D cameras similar in functionality (see "Features") — it allows you to record sound of higher quality and with less noise than when using the built-in microphone.

— Webcam feature. The ability to connect the device to a computer and use it as a webcam — for video calls, broadcasting video directly to the Web, direct recording to a computer, etc. The advantage of camcorders over traditional webcams is the higher resolution and image quality. At the same time, this advantage has not been very noticeable lately, but larger size make camcorders less convenient; Therefore, this function is not widely used.

— Direct copy to HDD. The ability to connect an external hard drive directly to the camera and copy footage to it without using a computer. This feature is especially useful in situations where you need to make a copy (for example, to free up camera memory) and the computer is not nearby.

— Direct printing. The ability to connect the camera to a printer (to print captured photos) directly without using a computer. Software tools in such models can have quite extensive print management options: image selection, printing multiple copies, size and number of prints per sheet, print quality, error messages, etc. Typically, direct printing uses PictBridge technology using a USB connection. It must be supported not only by the camera, but also by the printer; at the same time, the connection does not require additional configuration, driver installation, etc.

The capacity of a regular camcorder battery is the amount of energy that it can hold on a full charge. In portable electronics, this parameter is measured in mAh; 1 mAh corresponds to the amount of energy that allows you to give a current of 1 mA for 1 hour. Of course, the higher the capacity, the longer the battery can last; however, keep in mind that the actual power consumption and battery life of modern cameras depends on a huge number of factors, ranging from the class (see "Features") to the specifications of individual electronic components. Therefore, in fact, the battery capacity is a purely reference characteristic, and it is impossible to compare different models with each other by it — for this you should use the directly claimed battery life (see below).

The presence of remote control in the camera package. The advantages of this feature are obvious: the remote control allows you to control the camera from a distance, without having to approach it. One situation where the remote control can be especially useful is when the operator is filming himself, for example, when recording a demo video. The remote control makes it possible at least to start/stop recording, but other adjustments can also be provided, for example, changing the magnification, applying special effects, or capturing a photo. In addition, the remote control usually also provides control over the playback of recorded materials — both separately on the camera and when it is connected to an external screen.
