The ASTAT-CN from Novoflex is a supportive tripod collar designed to be used with Novoflex's line of Nikon and Canon to Leica SL lens adapters.
When mounted, the collar relieves pressure from the SL's lens mount by supporting the adapter and lens with the help of an optional tripod or monopod. The collar itself is simple and easy to install; simply loosen the clamp with the integrated knurled knob, slide it over the lens adapter, and then re-tighten.
Offering a variety of connection options, the ASTAT-CN may be mounted with a 1/4"-20 or 3/8"-16 screw thread, or via the built-in Arca-type dovetail.
