I have the tripod since January 2012 in use and am completely satisfied. With an extension height of 1.65 m, it is made for me because I'm not bigger. Without center column off there are 1,33m + SBH -100 is the camera exactly at eye level. The tripod makes a very high-quality impression the extracts can be easily operated, the legs can be divided into 3 stages abduction 25 ° 50 ° and 80 ° so can be used in rough terrain using the built spirit level roughly balancing and all 3 legs have cold grip protection on top end and spike-studded rubber feet. The center column is hexagonal and is infinitely off and has a safety stop. While holding the safety stop allows the center column pulling out and they can also be rotated by 180 ° insertion. The center column has at the upper end of the sliding surface a rubber ring as a damper. Furthermore, the center column has a hook is the spring-loaded, there you can attach a weight. Through the continuously variable tilting of the center column, it is well suited for ground-level shots. The Alta Pro AT comes with a lot of accessories: - Stativtasche because the tripod including screwed ball head fits in - Stone bag is attached to the 3 legs, to complain as the tripod with 2kg is not very difficult - Multifunctional tool for the tripod - 1/4 - 3/8 Adapter is in the accessory socket of the center column. I use the tripod with a Vanguard SBH-100 head and a 50D / 7D and heaviest lens is a 2.8 / 70-200mm I can nothing better representation. The price - performance ratio is super, drum It is a buy rating.
