Almost no one is perfect, and you can use even the best camera, but if your hand shakes when you press the shutter, ruin the perfect shot. In the case of video shooting, the situation may turn out to be even worse - moving behind a moving object and not always having time to look under your feet, an operator, especially an inexperienced one, will inevitably provoke shaking. However, you probably noticed that professionals do not have this problem.

Actually the trick is not to long and diligently work out the stability of the hand in a stable position, but to buy special equipment that smooths out the shaking for the recording equipment . Such a device is called a stabilizer or steadicam.

There are many different models of gimbals available for your camera, but they all come in two main classes, radically different in how they work. Accordingly, the steadicam can be either mechanical or electronic.

The mechanics certainly came before . Mechanical steadicams are often referred to as handheld because they look like a free-floating camera retainer with a handle. When shooting with such equipment, the operator controls not so much the camera itself as the holder. It works on the principle of classical scales - the place for mounting the camera is always in a horizontal position, and if you jerk the handle sharply, the equipment will return to the “correct” position by itself, but it will do it smoothly, without blurring the picture.

A professional gyro stabilizer of this type works in all axes, which is why it is called that - three-axis

Those who want to save money and simply do it all can make such a device even on their own.

As befits the ageless classics, the mechanical steadicam has a lot of advantages. Here are just a few of them:

• the mechanism is very simple, consists of a minimum of parts, therefore it is relatively inexpensive;
• the mechanical steadicam does not depend on the weather in any way, it does not need to be waterproof, because it is not afraid of moisture ingress - if only the camera would withstand;
• such a stabilizer functions exclusively thanks to the elementary laws of physics, it basically does not have anything like a power source, and therefore it does not need to be recharged and can work indefinitely.

If you already think that you are in love with this type of device, be prepared for the fact that it also has significant drawbacks . Firstly, the unit must be properly adjusted, otherwise, instead of an ideal horizontal position, it will constantly skew your camera along one or more planes. Secondly, during sharp turns, the rotating equipment may simply not “catch up” with the frame, which must be photographed quickly, or, due to inertia, at first turn more strongly than we would like. In a word, a mechanical steadicam is very simple at first glance, but you still need to get used to it.

The electronic unit acts in a fundamentally different way - electric motors return the camera to the correct position . Deviations from the correct position are detected by sensors, so that even a small angular misalignment, which you would not have noticed with the naked eye, will be fixed and corrected. Electronic stabilizers are divided into two-axis and three-axis, the latter, of course, give a much better picture than the former.

The advantages of using an electronic steadicam are obvious. First of all, it is easy and simple to set them up, "smart" equipment itself will tell you what is the best way, will double-check everything correctly . Thanks to this, both photos and videos are obtained at the level of professional shooting - provided, of course, that you have a good camera and that you have configured it correctly.

But here, too, there were some drawbacks . Firstly, technologically sophisticated equipment a priori cannot be cheap - that’s why it’s not worth it. Secondly, the electronic steadicam works thanks to the battery, and if it is discharged, the entire unit turns into useless. Thirdly, most typical electronic stabilizers, as befits an electrical appliance, are afraid of contact with water. The instructions for them specifically indicate that they are not suitable for shooting outdoors in rainy weather.

Of course, there are waterproof models, but for the quality, as is often the case, you will have to pay extra.

Model rating

Of course, the best stabilizer that would be equally good for any camera does not exist in nature - in all cases you need to adapt to the camera and shooting features. Nevertheless, under the same conditions and one model of recording equipment, certain steadicams will have an advantage over all others. In view of this, our rating will be rather arbitrary - none of the models presented in the list may be suitable for an individual reader. Nevertheless, these are the best or very popular models in their classes, which simply should not be ignored if they suit you according to the characteristics.

Feiyu FY-G5 . While everyone criticizes Chinese goods, it is the steadicam from the Middle Kingdom that is considered by millions of users to be the most compact among all three-axis ones - it weighs only 300 grams. By the way, it will cost a lot - about 14 thousand rubles, but it has a universal mount where you can attach any camera.

Dji Osmo Mobile . Another "Chinese", which is regarded by many as the best solution in terms of functionality and quality. It is worth, however, even more expensive than the previous model - from 17 thousand rubles.

SJCAM Gimbal . Among electronic models, it is often called the most affordable - if you wish, you can find it for 10 thousand rubles with a penny. Many consider the disadvantage of the unit that it is suitable only for action cameras of the same manufacturer, but it is a pleasure to operate them, because the holder has the necessary buttons that allow you not to reach for the camera.

Xiaomi Yi . A stabilizer from a famous manufacturer attracts the attention of fans of this brand, who buy a steadicam for a camera of the same company. However, it is worth noting that at a price of 15 thousand rubles, the structure is surprisingly devoid of a holder, so you will have to additionally buy a standard monopod or a tripod.

Steadicam . This, of course, cannot be done, but the enterprising Chinese decided to produce a mechanical steadicam under the brand that is literally called that. This somewhat complicates the search for the right product, but the designated model made of aviation aluminum weighing 968 grams costs less than 3 thousand rubles, and is considered one of the best in its category.

Beholder MS-PRO . Stabilizers for professional needs cost much more, but they have improved properties. For this model, you will have to pay about 40 thousand rubles, but it is an excellent, rare for amateur steadicams, combination of lightness and strength. An aluminum unit with a modest weight of 700 grams will withstand a camera weighing up to 1.2 kilograms.

Zhiyun Z1 Evolution . For an electronic stabilizer, it is very important to work as long as possible without additional recharging, this particular model, for 10 thousand rubles, meets this requirement in the best possible way. The battery has a good capacity of 2000 mAh, and the generous manufacturer, just in case, also added two of these to the package.

Zhiyun Crane-M . The same manufacturer as in the previous case, but a different model. This steadicam, for 20 thousand rubles, is often called the best for small cameras in the weight range of 125-650 grams, it is also often used to stabilize smartphones.

In this case, the supplier also decided to put two batteries in the box at once, and the life of each of them on one charge is estimated at an average of 12 hours.

How to choose?

When purchasing a stabilizer for a video camera, you need to understand that the existing variety of models does not exist just like that, and it is impossible to choose the conditional best copy among them, for all occasions. It all depends on what needs you buy a steadicam for. From the above, it could be concluded that electronic steadicams seem more relevant for professional video filming, in general it is true - it is easier and easier to set up.

However, even this criterion strongly depends on the situation, and if you do not shoot some action in its very epicenter, then the mechanics may well be enough.

In any case, when choosing, it is worth focusing on very specific criteria, which we will consider in more detail

1. For which camera (mirrorless or SLR) this model is suitable . The connection of the steadicam with the camera itself should be as reliable as possible, ensuring that the recording equipment does not separate from the holder at a sharp turn. At the same time, some stabilizers are produced with an eye to a specific camera model - they provide better grip, but will not work with alternative equipment. Most of the models on the market have a standard connector and fit all cameras.
2. Dimensions . A stabilizer is hardly needed at home - this is equipment that you take with you on business trips, travels, on trips. Therefore, compactness for such a unit is undoubtedly a big plus. Paradoxically, but it is the small steadicams that are usually more technologically advanced - if only because the mechanics are always large, but they have no additional functions.
3. Permissible load . Cameras can vary significantly in weight - all GoPro fit easily in the palm of your hand and weigh accordingly, and professional cameras do not always fit on the shoulder of a sturdy man. Obviously, a steadic should be chosen so that it is able to withstand the weight of the shooting equipment that they want to fix on it.
4. Weight . In most cases, a gimbal with a camera attached to it is held on an outstretched arm. This position of the hand is in many ways unnatural, the limb can get tired even if you do not hold anything in it. If the equipment is also heavy, it is simply not possible to shoot for too long without a break, and sometimes it is simply criminal to interrupt. For this reason, lightweight models of steadicams are more appreciated - they make the hand less tired.
5. Operating time without recharging . This criterion is relevant only when choosing electronic steadicams, since mechanics does not have a power source at all, and therefore is capable of "breaking" any electronic competitor. By saving on a battery with a low capacity, you run the risk of finding yourself in a situation where there is a stabilizer, but you cannot use it.

Consumers often wonder which model to choose for DSLR and mirrorless camera types. In this sense, there is no fundamental difference - be guided only by the criteria that are given above.

How to do it yourself?

Probably, such a person has not yet been born who, at home, with his own hands, would design an electronic stabilizer. Nevertheless, the design of its mechanical counterpart and the principle of its operation are so simple that the task no longer seems insurmountable. A homemade steadicam, made with great care, is unlikely to be much worse than inexpensive Chinese models, but will cost mere pennies . At the same time, it should be understood that you should not expect a direct amazing result from such handicraft products, therefore it makes sense to additionally process the video through video editors.

Theoretically, you can experiment with any materials at hand, but in most cases, a reliable and durable unit is assembled, of course, from metal. It is noticed that the simplest mechanical stabilizers give a better result with an increase in mass, therefore it is hardly necessary to count on the fact that the final product will turn out to be light.

Horizontal and vertical strips should be made from metal blanks. Rigidity is mandatory for both - swinging weights should not swing the horizontal bar from which they are suspended, and the vertical bar must successfully resist torsion and bending . They are connected to each other with a screw connection, designed so that the angle between them can be changed easily and without additional tools by unscrewing and unscrewing the individual parts. The camera will be mounted on a vertical bar. It is necessary to adjust the device according to an ordinary bubble level, or, if the recording equipment is able to do so, according to its sensors.

The length of the horizontal bar is needed as long as possible - the farther the opposite weights, suspended along the edges of the bar, from each other, the better the stabilization . In this case, the fragments of the stabilizer should not fall into the frame even at the minimum focal length, and this imposes certain restrictions on the maximum allowable length of the structure. A solution to the problem could be by lengthening the vertical bar with a higher camera attachment point, but this would make the design too cumbersome.

As weights, you can use any small, but rather heavy objects, including ordinary plastic bottles filled with sand. The exact weight of the weights, which will provide reliable and high-quality stabilization, can only be determined empirically . - too much depends on the weight and dimensions of the camera, as well as the length of the horizontal bar and even the shape of the weights themselves. In homemade designs for cameras weighing about 500-600 grams, a homemade stabilizer with weights can easily weigh more than a kilogram.

For the sake of ease of use, handles are bolted to the structure in different places, which can be purchased at a low price . Where exactly they should be placed, in what quantity (for one hand or for two), depends only on the designer's flight of imagination and the characteristics of his camera, including its dimensions and weight. At the same time, before the final assembly, you need to fully make sure that even at the minimum focal length, the handle does not fall into the frame.

Many self-taught designers note that a properly made rigid inertial steadicam turns out to be more practical and more reliable than inexpensive pendulum models from a store . With the correct calculation of the dimensions and weight of the steadicam, the camera will display a normal picture, even if the operator is running over bumps. At the same time, the control of the structure is extremely simple - when the shaking increases, the handle must be squeezed harder, and when it decreases, the grip can be loosened.
