easy (and) brilliant

The decision for the Sprint Pro was a compromise of size, weight, price and quality.
With less than 50 cm pack size and weight about 1KG can just take anywhere the tripod back. Thus, it is also quite often used, usually with a D5100 and a smaller lens thereon. But the stability is easily sufficient. Even with a 70-300mm lens on it and fully extended legs you can use it yet. Mostly, however, I go from the rather thin legs only 70 or 80 per cent, then wobbles guarantees nothing. For low working heights the Sprint mini-variant might have been interesting, but I am very glad that we can place the camera on 1.50m or higher.
The only weak point in my view are the plastic clips to determine the extension length of the segments. While this bite very tight, but are not adjustable and fastened with riveted axles. This construction could adversely affect the long-term durability, but works as already mentioned only once very good.
Now for the positive properties:
You may be here the ball head to mention. All moving parts are made of steel or injection here. Even with a slight tightening torque of Feststellhebelchens the thing holding the camera bombproof. The one-hand operation could not be better. Smooth horizontal panning when films are possible in virtually any position of the center column. On the possibility of being able to make vertical pivot maneuvers I like to do without. There are no troublesome for small lever off, and to photograph me the ball end variant anyway thousand times prefer.
The head plate of iron is tiny, snaps into its frame of itself and holds the camera with no play. Excellent! As a spare part, it is quite expensive.
The tendency of the legs can be easily adjusted with one hand with mounted camera.
Overall, my experience handling Trumpf, VA's out in the dark and frequent relocation. Fast and secure assembly and disassembly are required. In this respect, the Pro Sprint is really well done.
