Review (5/5): works with the Zeiss Apo Sonnar T* 2/135 ZE with less-than-complete contact
I used this with a Zeiss Apo Sonnar T* 2/135 ZE on a Wimberly head to shoot multi-row panos and it worked well.
It fits just camera-side of the knurled portion with the hyperfocal markings.
The smallness of this area meant that the entire clamping surface was not in contact with the lens, but I was able to tighten this enough to to make the connection sufficiently rigid.
