Comparison Cullmann Alpha 2500 vs Arsenal ARS-3750

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 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".

The maximum camera weight allowed for this tripod.

If a tripod is purchased for use with a smartphone or action camera, you can ignore this parameter: the weight of such gadgets usually does not exceed 200 g, any tripod of the corresponding specialization can easily carry such a load (see "Intended Use"). Compact "soap" cameras generally weigh up to 300 g, and amateur camcorders — up to 700 g; but in both cases there are also more massive models. This should be taken into account when choosing a desktop tripod (see "Installation") for such equipment — some desktop models have rather modest weight restrictions; but with floor difficulties usually do not arise.

But if a tripod is bought for professional equipment, you should pay special attention to the allowable weight. So, a professional video camera can “pull” 2.5 kg or even more; the average weight of a SLR camera is 600 – 800 g, but this is only the "carcass" to which the weight of the optics is added — and in some powerful telephoto lenses it can exceed 2 kg. So for such devices, quite “hardy” tripods may be required.

The main material used in the construction of the body or legs (depending on the type) of a tripod.

— Plastic. The main advantage of plastic is its low cost, due, among other things, to ease of processing and suitability for creating parts of complex shape. In addition, this material can be flexible, have any colour, and even become transparent. On the other hand, its strength is significantly lower than other tripod materials; it is more than enough to work with light weight, however, plastic is not suitable for supporting massive equipment and creating long supports that are subject to significant bending loads due to the large length. Therefore, the main scope of this material today are clamps and small table stands, including flexible design (see "Type").

— Aluminium. Aluminium-based alloys have a combination of high strength and low weight, making them well suited for the construction of tripods of any format — including and classic full size. The cost of this material, however, is somewhat higher than that of plastic and steel, but not by much, and the mentioned advantages more than cover this drawback. Because of this, this material is the most popular in modern tripods, it is widely used in almost all types and price categories.

— Steel. Steel is characterized by high strength — even higher...than that of the aluminium alloys described above, at a slightly lower cost. At the same time, this material has a rather large weight. On the one hand, this contributes to stability, on the other hand, it makes it difficult to carry from place to place. And although the latter is relevant mainly for floor tripods (see "Installation"), however, even in compact desktop models, steel is still rarely used.

— CFRP. The most advanced of the materials used for modern tripods. Carbon fibre, or carbon fibre, is a composite composition of carbon fibers filled with a filler — usually a special resin. In terms of strength characteristics, this combination is comparable to steel, while this material weighs very little, which is especially useful for full-size tripods. Its main disadvantage is the high cost, which is why professional premium models remain the prerogative of carbon fibre. In addition, carbon fibre requires fairly careful handling due to its sensitivity to point impacts — cracks easily appear from them.

— Metal. This option is indicated in cases where the manufacturer, for one reason or another, did not specify the composition of the metal in the characteristics. Most often, this refers to aluminium or steel, the properties and features of the use of both are described above; however, other types of metal may occur. Anyway, when assessing the reliability and durability of such a tripod, it is best to focus on its price category.

— Carbon. Another name for the CFRP described above; used by some manufacturers for the sake of brevity and "solidity of sound".
