Folks,

I've got a project where I need to rigidly mount my camera (a T2i) and an 85L f/1.2 prime to an optical table. The lens will be set to its minimum focus and the the target will be put in-focus by moving a micrometer stage until it's centered and sharp in live view X10 viewed on an HDTV. My hope is that someone in the group has a suggestion on how to mount the lens (more so than the camera) rigidly. Obviously I can mount the camera with the 1/4-20 hole on the bottom. I could mount a quick-release plate, etc. However, I'd prefer to find a mount that holds the lens first. Then I can support the body using adjustable hardware I already have around my lab.

Does anyone have a suggestion of a tripod ring or some other mount that can hold this lens without translating or spinning?

Thanks!
