Comparison Canon LEGRIA HF G26 vs Canon LEGRIA HF G30

— 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 noting the p...resence 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.

Focal length of a standard video camera lens in terms of a 35 mm full-frame sensor. This parameter is also called the "equivalent focal length" — EFL.

The focal length itself is the distance from the optical centre of the lens (when focus to infinity) to the sensor, at which the sharpest image is obtained on the sensor. It is one of the key characteristics of any lens, because. determines the viewing angles, the degree of approximation and, accordingly, the specifics of the use of optics. At the same time, it is impossible to compare different options in terms of the actual focal length: the laws of physics are such that with different sizes of sensors, the same focal length will give different viewing angles. Therefore, EFL was adopted as a universal characteristic and criterion for comparison. It can be described as the focal length that a 35mm lens with the same viewing angles would have.

The larger the focal length, the narrower the viewing angle will be and the higher the degree of approximation of the visible scene. Optics with EFL up to 18 mm belongs to the class of ultra wide-angle ("fisheye") and is used primarily to create artistic effects. Distances up to 40 mm correspond to "wide angles", 50 mm gives the same degree of approximation as that of the naked eye, the range of 70-100 mm is considered optimal for portrait shooting, and large values allow the use of optics already as a telephoto lens. Knowing these provisions, one can approximately...evaluate the capabilities of the lens and its suitability for certain tasks; there are more detailed recommendations, they are described in special sources.

Also note that modern video cameras are usually equipped with lenses with a variable focal length (zoom), which allows you to change the degree of approximation and viewing angle; see "Optical Zoom" for details.

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.

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 conditions;...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.

— Component. An interface for transmitting a video signal in an analogue format, dividing the “picture” into three components (hence the name) and transmitting each of the components via a separate wire. Due to this, a fairly high image quality and good bandwidth are ensured: the component interface surpasses S-Video in quality and is suitable even for high definition (HD) operation. On the other hand, it does not provide working with audio — so if you want to hear sound, you will have to take care of a separate channel for its transmission. On stationary video equipment, three separate RCA connectors (“tulip”) are usually used for component connection, the same format can be used in professional video cameras, but in amateur models (see “Features”) the component output has a more compact design — for example, in the form of a 3.5 mm mini-jack socket.

— USB. A universal interface used in computer technology to connect various external peripherals. It is extremely widespread, available in the vast majority of modern desktop PCs and laptops. When connected to a computer via USB, the camcorder also functions as a peripheral device. The most popular use of this connection is for copying footage, but it may include other options depending on the model: remote control of the camera, firmware upgrade, USB streaming, webcam operation (see "Features") . In addition, it is this...interface that is used for direct copying to the HDD (ibid.); in this case, the camera plays the role of a control device, and the storage plays the role of a peripheral.

— HDMI. High-speed digital interface for transmitting video and audio signals over a single cable. Has enough bandwidth to work with high-definition video and multi-channel audio. The HDMI output in the camcorder is very convenient for using it as an external player when viewing footage: the vast majority of modern TVs and monitors have at least one input of this standard. It is also widely used in other video equipment.

— S-video. Interface for transmitting video signal in analogue format. Like component connection (see above), this standard does not work with audio and uses separate transmission of signal components — however, in this case there are 2 of these components, not 3. This, on the one hand, somewhat reduces the quality of the “picture”, on the other — allows you to use one cable and one connector instead of three. But one of the significant shortcomings of S-Video is the impossibility of working with HD — the bandwidth is only enough for a standard definition signal.

— IEEE 1394. Also known as FireWire. Although IEEE 1394 is now a very versatile interface used in computer technology, it was originally used specifically in camcorders — primarily to “capture” video from a magnetic tape and convert it to files. This application is relevant even now — almost all cameras with miniDV (see "Media type") have such an output, it is also found among other devices, mostly professional ones (see "Features"). A FireWire connection can provide other options – similar to the USB described above.

— SDI. A digital interface used to transmit video and audio signals, as well as service information. The bandwidth of SDI is somewhat lower than that of HDMI, but for a number of reasons it is much better suited for professional use and is quite widely used in related video equipment, including cameras. But in amateur models (see "Features"), the outputs of this standard are not installed.

— AV-output. Connector for transmitting video and audio in analogue format. This interface is also called "composite", but the classic composite input or output uses several RCA connectors (one for video and one for mono audio, or two for stereo). In camcorders, this interface is usually made in the form of a 3.5 mm jack (mini-jack), and appropriate cables are used to connect to full-size video equipment. The main advantage of the AV-output over other analogue standards (component and S-Video, see above) is the ability to transmit video and audio simultaneously. At the same time, in terms of image quality, it loses to the mentioned options due to the fact that all components of the video signal are transmitted over one cable and the resistance to interference is low.

— Microphone input. Connector for connecting an external microphone to the camcorder. This feature is important in cases where the microphone needs to be placed at some distance from the camera — for example, when shooting TV programs or reports. Professional models (see "Features") may have several of these inputs, and they can also be used for multi-channel audio recording and other specialized applications. Please note that XLR microphone connectors are listed separately in our catalog (see below).

— XLR microphone input. The presence in the design of the camera at least one input for an external microphone using an XLR connector. The role of the external microphone is described in detail above. As for XLR, it is an interface widely used in professional audio and video equipment, including cameras. Its main feature is the possibility of the so-called balanced connection; this connection is highly resistant to interference even with long cable lengths and is well suited for use with high quality microphones. The connector itself is quite large, but given the sizes of professional video cameras, this is not a drawback. It is worth noting that 1 channel of sound is transmitted through one XLR input, so several of them can be provided — usually two, for stereo recording.

— Headphone jack. The presence of a headphone output in the design of the video camera. The main function of this feature is to listen to the sound that accompanies the captured video. Headphones generally provide better quality than the built-in speaker (see "Features") and are even more comfortable in some situations, such as in a noisy environment or when silence is required. Another purpose of the headphones is to control the sound characteristics right during the recording process, but this feature is usually found in professional models (see "Features"). Most often, a standard 3.5 mm mini-jack socket is used as a connector, but there are other options; all of them are included in this section — except for the XLR described below.

— XLR headphone jack. The camcorder has a headphone output using an XLR connector. The features of the connector itself are described in detail above in the paragraph “XLR microphone input”, and the role of the headphones is described in the paragraph “Headphone output”. At the same time, we note that XLR, being a professional interface, is intended not so much for listening to recorded materials, but for other, more serious tasks — in particular, monitoring sound during filming.

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 battery life of the camcorder from a fully charged standard battery. Usually, the specifications indicate the battery life in the recording mode, but in perfect conditions — without using additional features such as zoom, backlight, etc., which also “eat up” the charge. And if there is a viewfinder (see "Features"), the shooting time is usually indicated through this device, and not through an external display. Therefore, in fact, the battery life may be less, but in general, this parameter quite clearly describes the capabilities of a particular camera, and different models can be compared by it.

Note that for many cameras, in addition to regular ones, also “reinforced” batteries are produced, which allow increasing battery life by 2-3 times. Therefore, if you are not satisfied with the operating time in the selected model, it makes sense to ask about the availability of such batteries.
