A7 with collapsible lens

[cosmonaut]

Is is ok to use a collapsible lens on a Sony a7/7R?

It was not recommended on the Ricoh gxr w/ m mount module. It is due to possibility of collapsing into the sensor. I have heard of people using collapsibles, but limiting the collapse by using something like an ugly fat rubber band or plastic tie, so it can never collapse all the way.

I would take some careful measurements before u even think about trying it.

Personnelly I would not try it myself.

A7r: the Perar 3.5/35 can be used, this combo is always in my bag.

Thanks Gary. I do have a Voightlander 40mm SC I'll just stick with that. Leave the collapsible on the M4.

Jupiter 12, not collapsible but with giant rear element, works on A7.

I just got an a7 and can confirm that the following collapsible lenses work just fine, fully-collapsed, with the CV Leica M to Sony E mount adapter:

• Leica 90mm Elmar
• CV 50mm/2 Heliar classic
• CV 50mm/3.5 101 Heliar (LTM, pictured below)

50mm Elmar 2.8 (older version, not the 90's version) collapses into my A7r
