Stabilizer for the camera: design, purpose

Both amateur photographers and professional camera users are very familiar with the difficulties that arise in the process of filming directly from the hands. First, there is a high chance of getting a blurry picture, and secondly, even in the absence of an apparent turbidity effect with a higher probability, the frame will not be sharp enough. To eliminate these troubles helps stabilizer for the camera, which can have a different performance, but serves for one task - creating optimal physical conditions while fixing the frame.

The purpose of the stabilizer

Use this technology should be in cases where there is a risk of distortion of image quality due to unintentional movement of the device. Optical stabilization compensates for the angles of movement and eliminates camera shake to prevent blurring of the picture at long exposure. It is important to understand that the presence of this function in the camera practically does not attract negative factors of exploitation, so it certainly will not be superfluous. Another thing is that in some cases the stabilizer for the camera does not save the situation, and can often be replaced by an ordinary tripod. Although it is still recommended to combine different ways to stabilize and reduce jitter effects to obtain high-quality images.

Camera stabilizer device

In the traditional design, the optical stabilization module is integrated into the lens of the device and represents a whole set of functional components. In particular, this complex is formed by a movable optical element in the form of a lens, which can enter the optical system of the lens. Also included in the stabilizer are angular velocity sensors that fix the camera's fluctuation parameters, which allows the system to adjust the optimum balance characteristics. An important part, which is also provided by the camera stabilizer, is the electromagnet. Due to this part, the optical element is moved based on the readings from the aforementioned sensors. For the coordination of individual components of the system is the chip: the function of the stabilizer largely depends on its function.

Varieties of systems

High-level stabilizers are usually divided into two types - VR systems from Nikon and IS modules, developed by Canon specialists. Often, the end results of both systems have a similar quality - especially in the eyes of non-professionals. An important feature of these systems is the possibility of improving the quality of shooting in poor lighting. Radical departure from this principle of the integrated anti-vibration concept was the manual stabilizer for the camera, which in essence is a more ergonomic version of the tripod. Usually such devices, called stedikam, are used in equipping video cameras, but recently they are increasingly being purchased by camera users.

Another direction is the stabilization system used in SLR cameras by Sony and Olympus. In this case, the stabilizer for the camera is not built into the lens, but into the matrix base of the device. The advantages of such solutions include compatibility of the module with virtually all lenses, since the system interacts not with optics, but with the filling of the main device.

Operating modes with stabilizer

As a rule, two modes are distinguished, under which the camera uses the stabilizer function - the continuous and the stabilizer function. The best quality allows you to get the first one-shot mode, because during its use the camera, roughly speaking, "freezes" until the moment of making a picture. But also the continuous format of the stabilization system can be justified, if it is required in the course of dynamic shooting for a short period of time to get a few photos. To improve the quality of such shooting, just recommend using accessories for the camera in the form of the same manual stabilizer. The main correction module will eliminate significant and abrupt deviations, and the tripod initially minimizes them. But even with this support, you should not count on creating high-quality images.

How to make a stabilizer with your own hands

It's almost impossible to implement an integrated module for an objective or matrix of a camera with your own hands, but it makes sense to try the technology of creating the same steadicam. In essence, a simple stabilizer should be obtained, the leveling effect of camera shake. The work will require a basic metal bar, which will be attached to the camera, the bearings, as well as devices for manipulating the mechanism.

So, the essence of the design will be to reduce the vibrations transmitted to the camera from the hands in the process of shooting. The main component of the system is the base, damping oscillations. It is formed by a set of weights, the mass of which can vary, and the system of bearings fixed at the turning points of the camera relative to the axis of the rod. To ensure that the self-made stabilizer does not fail at the right time due to miscalculation in the power structure, it is also necessary to provide reliable fixators for its individual parts. Since both the rod and the associated equipment will not be subjected to serious loads, you can limit yourself to conventional mounting brackets. In addition, it is important to complement the design and ergonomic handles, since during prolonged shooting fatigue from confinement can increase the amplitude of the oscillations.

How much does the stabilizer of the camera cost?

The simplest stedicam models can be purchased for 1,5-2 thousand rubles. It can be a universal device, which is suitable for almost all camera models. In the middle price segment, more quality and ergonomic designs are offered with a cost of 5 thousand. It makes sense to pay attention to the complex stabilizer for the camera, which will consist of an integrated module, manual damping equipment and a floor rod. Such sets cost already about 10-15 thousand.

Conclusion

In choosing a stabilizer, much depends on the shooting conditions. If it is a question of "field" conditions and a dynamic format of photo-hunting, then there is no way to do without a built-in module in the matrix or camera lens. However, in the home or studio environment, external accessories for the camera in the form of the same bar or stedicam will also help. Here, much will depend on the organization of filming. Also, the quality of the images will be affected by exposure - the period of time during which the apparatus without corrections focuses on the object. The longer it is, the higher the chance to get a high-quality picture even without the use of stabilization systems.
