I have that Summicron. It collapses easily on my Sony A7rii. It is only like 13’mm deep not including the m mount adapter. I have other collapsible lenses that won’t collapse on the Sony

Hey Shawn, you say they won't collapse on the Sony, but why?

You run the risk of it hitting the shutter or sensor?

When the Ricoh GXR launched their M-Mount module, it came with a plastic mold of the lens mount that you could use to test if a lens would hit something when collapsed / or a wide angle lens that protruded into the camera.

Many people use rubber gaskets to prevent the lens from collapsing all the way.

Though I can't be sure that's what he meant.
