Comparison Bosch BT-150 vs Bosch BS-150

The minimum height relative to the base at which the tripod base can be mounted.

The lower the minimum height, the better the tripod is suitable for macro and product photography; in addition, the range of height adjustment available to the user depends on this indicator. Note that for models with the ability to flip the boom (see below), the minimum height is given for the traditional position of the boom, platform up. And if the claimed minimum is significantly less than the length of the tripod when folded (for example, 15 cm with a length of 50 cm), this means that the legs can “spread” to a horizontal position or close to it, thus lowering the entire structure.

The maximum height from the base on which the tripod base can be mounted.

For desktop use (see "Installation"), a large height is not required, therefore, in most of these models, this figure does not exceed 20 cm — the only exceptions are some specific monopods. Accordingly, the difference in height between different desktop structures in most cases does not matter much. But in the floor models, the most "undersized" have a maximum height of about 40 – 50 cm, and the highest ones are able to open up to 2.5 m and even higher. In such cases, the choice should take into account the specifics of use. So, it makes sense to specifically look for a model at 150 – 160 cm if it is fundamentally important to install the camera at eye level (eye level is usually about 10 cm lower than a person’s height). At the same time, most camcorders and many cameras have swivel screens that allow you to comfortably look at the device from top to bottom; and even in the absence of such a screen, bending down to the level of the camera is not so difficult. And it makes sense to pay attention to tripods with a height of 170 cm and above mainly in those cases when shooting over heads is planned — for example, reports from public events.

The presence in the tripod of a special mechanism that provides raising and lowering the central rod, in other words, height adjustment (usually by turning the corresponding knob). This function complicates and increases the cost of the design, but provides additional convenience: it is easier to set the exact height by turning the knob than to move the bar manually by opening and closing the lock. In addition, the movement is smoother — this is important in situations where the height needs to be adjusted right in the process of shooting.

In tripods with this function, the head has a special plate (platform) with a mounting screw for the camera, installed in the mounts, which ensure its quick removal and re-installation on a tripod. This design increases the efficiency of work: it is enough to screw the platform to the camera once, and installing / removing the camera (together with the platform) will be much faster and easier than if you had to screw it back to the tripod itself every time. Removable platform is considered mandatory for professional tripods.

The presence of a built-in tripod level — a device that allows you to control the horizontal position of the camera.

Bubble levels are most often used — in the form of a sealed flask with liquid and an air bubble: if the bubble is between the marks on the flask, then the camera is on the horizon. The simplest option provides one flask to control the tilt to the right and left in order to avoid a “littered horizon”; however, the design may provide another level that monitors the tilt back and forth, or one common two-axis bulb. And in the model with a horizontal rotation of the rod (see above), an additional level is often set — for the horizontal mode. Anyway, this function greatly facilitates the exposure of the camera "on the horizon".

Tripod head included. Most often, the head is supplied as a kit, however, some models (mainly professional level) do not come with a head — it is purchased separately and selected for the specific needs of the user (for more details, see "Removable head" and "Head type"). Therefore, in the characteristics of the tripod, this parameter is indicated separately.
