Ok, so I've got a Spotmatic with a Super Takumar 50 1.4 and 135 3.5 on the way. Along with those, I decided to get a set of tubes because I have read all about the Super 50 f/1.4 not being compatible with the 5D I have.
My question is wouldn't using the 7mm or 15mm tube, in the set, to further place the rear element away from the mirror, allow me to use this combo without either pieces making contact?
If this workaround is feasible, great. If not, I got a decent film setup cheap to run around with, I guess.
