I just obtained a "new" lens, a Geronar 300mm f9 which has a tiny chip (missing a half moon shaped 1 mm wide chip) at the edge of the rear element. This was fully disclosed by the seller, no surprise here.
I was just wondering how much effect, if all, it has: The Geronar is stated to have a coverage of 340mm, and I will use it on my 4*5. Can I assume that this chip might influence the projected image only at the edge of the cover circle, so no problem for 4*5 ?
Or is this is a too simple reasoning ?
best,
Cor
