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.
Rotation angle
The range of rotation angles supported by the steadicam.
In this case, it means turning the camera to the right or left, without tilting back and forth.
Tilt angle
The range of forward-backward tilt angles relative to the vertical position supported by the steadicam.
It can be written in different ways.
The simplest option is when one angle value is indicated in the characteristics. This may mean that the camera is able to deviate from the neutral position in both directions by the same angle, which is half the range.
Another recording option is used when the angles of inclination forward and backward are not the same. In such cases, the horizontal position of the camera on a vertical steadicam is taken as zero, the “—” sign indicates the maximum angle of camera deflection back, lens up, the “+” sign — forward, lens down.
Bank angle
The range of roll angles (to the side) supported by the steadicam.
Can be recorded in two ways (See "Tilt Range")
Max. controlled speed
The maximum controlled speed supported by the stabiliser is, in fact, the highest speed of rotation of the camera along one axis or another, provided by the device. This is the maximum rotation speed of the entire structure, at which the stabiliser automation can provide effective stabilisation along the corresponding axis (that is, keep the camera stationary).
This item is directly related to the purpose of the stabiliser — for shooting while hiking or cycling on flat terrain, a high stabilization speed is hardly necessary, but during surfing, acrobatic aerobatics and other similar activities, the “slow” stabiliser often turns out to be ineffective.
HD (720p)
HD (720p) video shooting capabilities supported by
the included steadicam camera.
The HD (720p) standard allows for a “picture” size of 1280x720 pixels. It offers a fairly decent picture quality with relatively small file sizes and low requirements for the processing power of video equipment.
Note that the quality of the video depends not only on the resolution, but also on the frame rate. 30 fps gives more or less normal image quality, 60 fps is good, and higher values are usually used in slow motion and mean that the camera supports this feature.
Field of view
Viewing angle of the complete steadicam camera.
Two things depend on this parameter: the width of the space that enters the frame, and the degree of magnification provided by the camera. A large viewing angle allows you to fit more of the surrounding space into the frame, but individual details in such a picture will look small. Conversely, a narrower angle limits the field of view, but gives a greater approximation and allows you to better see the details of what is still in the frame.
Optical zoom
The degree of optical zoom provided by the steadicam camera.
Optical magnification is carried out due to the so-called. zoom lens — a lens with a system of movable lenses that allow you to change the focal length and viewing angles. Such systems are noticeably more complicated and more expensive than electronic zoom, moreover, they are more bulky and less reliable, but they do not affect the image quality and visibility of fine details.
Photo megapixels
Resolution of photos taken with the Steadicam's bundled camera, in megapixels. Usually, this number corresponds to the working resolution of the matrix, and not only photos, but also the quality of the matrix as a whole are evaluated by it.
The number of megapixels is a rather ambiguous parameter. There is an opinion that the higher the resolution, the better the quality of the photos taken; However, it is not. The only thing that definitely affects the number of megapixels is the resolution of the resulting images and how clearly fine details will be visible in them: higher resolution allows you to achieve better detail. At the same time, increasing the number of megapixels without increasing the size of the matrix leads to a decrease in the size of each pixel and an increase in the noise level; so between two sensors of the same size, the overall image quality may be better with the one with the lower resolution.
