Comparison DJI Mini 4 Pro Fly More Combo (RC2) vs DJI Avata Pro-View Combo

The distance that a quadcopter can travel in the air on one full battery charge. Simply put, this is the drone's range in kilometers. Note that smaller, lighter drones tend to have a more limited flight range compared to larger, more powerful models. In the latter, it can reach 30 km or more. Also, the maximum flight distance is often influenced by weather factors and the load carried by the copter.

Maximum flight time of a quadcopter on one full battery charge. This indicator is quite approximate, since it is most often indicated for ideal conditions - in real use, the flight time may be less than stated. However, by this indicator it is quite possible to evaluate the general capabilities of the copter and compare it with other models - a longer declared flight time in practice usually means higher autonomy.

Note that for modern copters, a flight time of 20 minutes or more is considered a good indicator, and in the most “long-lasting” models it can exceed 40 minutes.

The highest speed that a quadcopter can achieve in horizontal flight. It is worth considering that in most cases this parameter is indicated for optimal operating conditions: a fully charged battery, low air temperature, minimum weight, etc. However, it is quite possible to rely on it both when choosing and when comparing different models of copters with each other.

Note that quadcopters were originally designed as stable and maneuverable aerial platforms, and not as high-speed vehicles. Therefore, you should specifically look for a fast quadcopter only in cases where the ability to quickly move from place to place is critical (for example, when the device is supposed to be used for video recording of fast-moving objects over large areas).

The speed at which the quadcopter rises up in the air or descends to the ground. Recreational, photo and video models tend to have more moderate climb/descent speeds, while professional or racing drones can rise and fall much faster. This indicator can be used to evaluate how quickly the copter can rise to a height for filming or, if necessary, avoid obstacles, and a high descent rate will be useful if the drone needs to be returned to the ground quickly and safely.

The physical size of the photosensitive element of a camera. Measured diagonally, often indicated in fractions of an inch — for example, 1/3.2" or 1/2.3" (respectively, 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 really are.

Anyway, for the same resolution (number of megapixels), a larger matrix means a larger size for each individual pixel; accordingly, on large matrices, more light enters each pixel, which means that such matrices have higher photosensitivity and lower noise levels, especially when shooting in low light conditions. On the other hand, increasing the diagonal of the sensor inevitably leads to an increase in its cost.

Aperture - a characteristic that determines how much the camera lens attenuates the light flux passing through it. It depends on two main characteristics - the diameter of the active aperture of the lens and the focal length - and in the classical form is written as the ratio of the first to the second, while the diameter of the effective aperture is taken as a unit: for example, 1 / 2.8. Often, when recording the characteristics of a lens, the unit is generally omitted, such a record looks, for example, like this: f / 1.8. At the same time, the larger the number in the denominator, the smaller the aperture value: f / 4.0 lenses will produce a darker image than models with f / 1.4 aperture.

The maximum resolution of photos that the standard quadcopter camera can take. This parameter is directly related to the resolution of the matrix (see above): usually, the maximum resolution of a photo corresponds to the full resolution of the matrix. For example, for pictures of 4000x3000 pixels, a sensor of 4000 * 3000=12 megapixels is provided.

Theoretically, a higher resolution of photography allows you to achieve highly detailed photographs, with good visibility of fine details. However, as in the case of the overall resolution of the matrix, high resolution does not guarantee the same overall quality, and you should focus not only on this parameter, but also on the price category of the quadcopter and its camera.

Also note that the high resolution of the camera affects the volume of the materials being shot, for their storage and transmission, more voluminous drives and “thick” communication channels are required.

The maximum resolution and frame rate supported by the aircraft camera (built-in or bundled) when shooting in Quad HD.

This standard is intermediate between Full HD (see above) and UltraHD 4K (see below); in cameras of modern drones, the Quad HD frame size can be from 2560 to 2720 pixels horizontally and from 1440 to 1530 pixels vertically. In some situations, such a video turns out to be the best option: it gives better detail than Full HD, while it does not require such powerful “hardware” and capacious drives as 4K.

As for the actual frame rate, the higher it is, the smoother the video turns out, the less motion is blurred in the frame. On the other hand, the shooting speed directly affects the requirements for the power of the hardware and the volume of the finished files. In general, values up to 24 fps can be called minimal, from 24 to 30 fps — medium, from 30 to 60 fps — high. Speeds of more than 60 fps are mainly used for shooting slow-motion video, however, for a number of reasons, such a possibility is rarely provided for in the QuadHD standard: relatively simple devices would require too powerful and expensive hardware for this, and in advanced copters, where the cost of electronics not particularly important, manufacturers prefer to use slow motion at higher resolutions.

The viewing angle provided by the standard quadcopter camera; for optics with adjustable zoom, usually, the maximum value is taken into account.

The viewing angle is the angle between the lines connecting the centre of the lens to the two opposite extreme points of the visible image. Usually measured along the diagonal of the frame, but there may be exceptions. As for the specific values of this parameter, in modern copters they can range from 55 – 60 ° to 180 ° and even more. At the same time, a wider angle (ceteris paribus) allows you to simultaneously fit more space into the frame; and a narrower one covers a smaller space, however, the objects that are in the frame look larger, it is easier to see individual small details on them. So when choosing by this parameter, you should consider what is more important for you: wide coverage or an additional zoom effect.
