Features
—
For smartphone. Mount for using a smartphone as a camera. Most often it is a kind of clamp, in which the body of the device is tightly clamped. Such clamps usually have a fairly wide range of adjustment for the width of the phone, which allows you to use this type of stabiliser with most modern smartphones, regardless of the diagonal. And some models can even work with compact digital cameras.
—
For camera. Attachments designed for use with full-size cameras — SLR and mirrorless (MILC). Such cameras are quite large and have a thread mount for a tripod. All these features are taken into account in the design of the stabiliser.
—
For action cameras. Stabilisers designed for action cameras — compact cameras used mainly for shooting dynamic scenes like sports, skiing, cycling, etc. Such devices, by definition, are designed for use in rather extreme activities, including surfing, skiing, paragliding, etc. However, the specific features of different stabilisers may be different, so before buying it's ok to clarify this matter separately.
Note that instead of the general name “for action camera”, the stabiliser specifications may contain the names of specific models of action cameras for which the device is designed.
Bank angle
The range of roll angles (to the side) supported by the stabiliser.
Can be recorded in two ways (See "Tilt angle")
Camera control
—
Joystick. Usually, the joystick has the form of a switch that can move or tilt in different directions. With it, the user can control the position of the camera mounted on the stabiliser — namely, tilt it and turn it to the sides.
— Buttons. The presence of buttons for turning the camera in one direction or another. Compared to joystick control, it is a less comfortable and convenient solution.
Shooting modes
—
Time lapse. Shooting video in time lapse mode involves a very low frame rate (one frame every few seconds, or even minutes). In the completed video, the effect of fast movement is achieved (for example, the day from sunrise to sunset fits in just a few minutes). However, this is the general principle of time lapse; but the specific ways of its implementation may be different depending on the specific model of the stabiliser.
-
Selfie mode. A separate mode for shooting selfies. This function can be implemented in different ways, depending on the purpose of the device. It is aimed at filming himself and the immediate environment of the operator.
-
Sports mode. The mode is designed for high-quality shooting of dynamic scenes in motion. In sports mode, the stabiliser automatically compensates for frame deviations from the reference location, while the motor runs at the highest possible speed.
-
Panorama. In this shooting mode, the camera attached to the device automatically rotates around its axis, taking a series of shots, from which the panoramic image is then “glued together”. Most often, this function involves the creation of horizontal panoramas. However, camera movement in the vertical plane can also be provided.
—
Tracking mode. Automatic tracking of a
...certain object by pointing the camera so that the shooting target is constantly in the centre of the image, or at least in the frame. The subject for tracking is set by the stabiliser operator.
— Inversion mode. This mode allows you to turn the device upside down, retaining all its functions and camera position. It will come in handy when shooting from atypical angles (for example, from the ground).Battery model
Model of the battery used in the stabiliser. This information is not very important when choosing: if you wish, knowing the battery model, you can find detailed information about it. However, the key characteristics of the battery are usually given in general information about the stabiliser. Nevertheless, model information can be useful if you plan to purchase an additional battery, or if you already have a battery and you need to evaluate its compatibility with the device.
Capacity
The capacity of the battery used in the stabiliser.
In theory, a higher capacity allows you to work longer without recharging, but the battery life of the stabiliser also depends on its power consumption. So, only models with similar performance characteristics can be compared with each other according to this indicator; and when choosing, it is better to focus not on the capacity, but on the directly claimed battery life.
Battery life
The maximum length of time the device will work before it needs its battery to be recharged. It is worth considering that the manufacturer indicates the maximum time, which does not correspond to real indicators due to the conditions and intensity of use.
Power bank function
The ability of stabiliser to work steadicam in
power bank mode — an external battery for various portable devices. It allows the device to share its energy with the phone, and the recording is not yet over.
Connection
There are two main types of connection in modern stabilisers:
Wi-Fi(more precisely, Wi-Fi Direct — for direct communication between devices) and
Bluetooth. Despite the difference from a technical point of view, in this case, these standards are very similar. First, they are both wireless. Secondly, both are used for direct connection with devices installed on the stabiliser — smartphones, action cameras, etc. (for more details, see "Features"). Thirdly, the specific functions of such a connection may be different, they should be specified separately for each model. However, such functions usually include at least control over the recording process (start/pause video recording, capture photos). So the main selection criterion for this indicator is what technology the connected gadget supports — Wi-Fi or Bluetooth.
Separately, we note that there are stabilisers that support both standards at once — these are mainly expensive professional models for cameras (see "Features"), where Wi-Fi is used to transfer video to an external screen, and Bluetooth is used for basic remote control.
