Physical Camera Perspective Shift and Real World PC-E Lens

[dj_buckley]

Does anybody know what the correlation is between a real world pc-e lens is and the physical camera perspective shift?

My PC-E lens has a maximum shift of 11.5mm in both directions. Is there any way to figure out what the corresponding perspective shift percentage value would be on the max physical camera?

11.5 / film_gate_mm = maximum shiftoffset I think...

Ok thanks, I'll give it a shot - would be good if Vlado could confirm

Also does your equation give you a percentage as per the new Physical Camera or does it give you the arbitrary result for the old VRay Physical Cam?
