Infinity stop

Just tested infinity stop on Byron, now I am sure that Schneider Apo Symmar 150/5.6 can not be used, just missed a little bit, about 2mm less for infinity, what a pity!

Really wanna use 150mm lens, maybe tailor made a special lens board for it, 2 or 3 mm extruded make it work.

So choose lenses from 135mm and downward, 150mm is out!

personal record...

127/4.7- 19S---32.7mm

plus 0.5mm each for center of infinity stopper gap
