Description The NOVOFLEX ASTAT-SL is designed specifically for the heavy SL lenses, the Vario-Elmarit-SL 2,8–4,0/24–90 mm ASPH and the Apo-Vario- Elmarit-SL 2,8–4,0/90–280 mm. This tripod collar relieves the weight on the tripod thread of the camera as well as of the camera bayonet and enables a well-balanced assembly of the lenses by moving the tripod mount point closer to their balance point. The tripod collar can be easily rotated, allowing a quick change from landscape to portrait format. Moreover, the collar is equipped with an ARCA- compatible dovetail as well as of 1⁄4“ and 3/8“ threaded holes. Thus, it is suitable for all compatible quick release units and nearly all tripods.
