Comparison DJI Osmo Pocket 3 vs DJI Osmo

— 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.

— With camera. Stabilizers equipped with their own cameras. These are integrated directly int...o the stabilizer's construction, eliminating the need for external devices for filming. Moreover, such models are inherently optimized for working with the built-in camera — at the very least, the user doesn't have to deal with balancing the load on the stabilizer's head. Note that the ability to remove and replace the camera with another is usually not provided, although there are occasional exceptions to this rule.

The presence of a display in the stabiliser design makes the operation of the device more comfortable and visual. Depending on the specific modification of the stabiliser, the screen can perform many functions. Usually, the display shows basic information about the operating modes used, the date and time, as well as the battery level. The most advanced stabilisers can display the image from the camera, which allows you to use it as a viewfinder with LiveView mode. At the same time, the screen size on professional steadicams can reach 3″ or more, but the vast majority of models are still equipped with a 0.5″ screen.

— Phone mount(like a screen). The ability to use your smartphone as your stabiliser screen. The device's camera is not used in this case: filming is carried out either on the built-in camera of the stabiliser or on the action camera attached to it. Note that the smartphone can be used not only as a viewfinder but also to control the camera; specific features depend on the stabiliser model.

— Focus control mechanism. A device that allows the stabiliser controls to focus the lens on the installed camera. It simplifies the use of manual focus lenses greatly.

— Two-handed handle. The two-handed handle increases agility, stability and precision.

— Quick release plate. This element makes it possible to quickly install and remove the camera from the stabiliser without using third-party tools.

— Tripod. The presence of a small tripod in the stabiliser kit — a tripod, which allows you to use the device in a stationary position, setting it on a flat hard surface. Usually the tripod is detachable.

— Remote control. The presence in the kit of a small remote control. It is convenient when the device is installed at a remote distance, for example, in a car.

— Bag / Case. The pre...sence of a bag or case in the standard package of the stabilizer. Bags often come with handles or a strap for convenient carrying, while cases are somewhat simpler — they don't have handles and are designed to be carried in a travel bag, backpack, etc. A bag or case protects the device from dust and other contaminants and to some extent shields the contents from damage in case of bumps or falls. Additionally, bags or cases can often be used to store extra accessories.

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.

The range of forward-backwards tilt angles relative to the vertical position supported by the stabiliser.

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 can deviate from the neutral position in both directions by the same angle, which is half the range.

Another option is used when the angles of tilt 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, and the “+” sign — forward, lens down.

The range of roll angles (to the side) supported by the stabiliser.

Can be recorded in two ways (See "Tilt angle")

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.

The maximum diagonal of the phone that can be installed on this stabiliser.

This parameter is more relevant for models for various purposes, not only for those that were originally designed for smartphones. Here we note that the maximum diagonal is a rather approximate parameter: models with the same screen size may have different actual dimensions.

HD (720p) video recording capabilities supported by the stabiliser's camera.

The HD (720p) standard allows the 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 which means that the camera supports this feature.
