On this one the "seperation" I refer to can only be seen if you hold the lens up to a strong light as tiny "swirl" marks around the outer edge of the element. The great majority of it looks clear and clean. Just for grins I took a shot with my 28-70 AL, which is seperated badly enough to be "fogged". (Since I can't get the element apart I put the lens back together so as not to lose parts.) The 28-70 outdid the 40 at all aperture settings. That was very surprising, as the 28-70 is in bad shape. I would love to see a comparison of a good 40 with say an M or A 50/2. Perhaps the seperation is causing far worse problems than I thought, the shots with this one were truly nasty.
