[Frameworks] Arri S Tech Question

[Jeff Kreines]

I hate to disagree with Scott. 

First, I assume your camera has a standard or Bayonet Arri mount, not PL. 

Arri Mount has a flange focal distance of 52mm. Olympus has a FFD of 46mm. That means a lens can’t focus to infinity, tho it could be used as a macro. Zooms will be somewhat disastrous as focus won’t hold through the zoom range.

If it were the other way — using the Olympus lens on, say, a C mount camera, there’s plenty of room — C Mount is 17.526.
