But even in the out of focus area there is detail to where in looking at a photo you would just say the Noctilux is "soft" wide open. And leave it at that. With the high resolution of the M8 the out of focus area is much more noticeable. At f2.0, because of the focus shift, on film it back focuses to where it is out of focus by nearly an inch. I think the shim will help this lens on a film camera as well as the M8. We'll see when I get it back. I still shoot film with my M's.
