Calculating adapted C-mount lens interference

[Netelia]

I'm trying to figure out whether a shorter focal length C mount lens is safe in both an OM1 MKII and an E-P5 using a Fotodiox MFT-C adapter, mainly being concerned about sensor contact with IBIS movement and shutter hits.

I have used several c-mount lenses on my GX85/GH5/GH7 cameras without incident, along with many others on these forums.  I have the right adapter that goes in a bit further and gives infinity focus, so there should be enough room.

I can't speak for other adapters or OM1 cameras, but it's definitely possible with the MFT flange distances.
