Quote:Not really, I was trained on the MTF bench yesterday and that was a lens we had lying around that is has been essentially locked in a metal block for life so it may easily be coupled to the MTF bench.The AF 55mm f2.8 indeed has the same optical formula as the 55mm f2.8 Ai/Ai-S. The main difference is in the duo-cam barrel design, allowing the AF version to go upto 1:1, where the MF versions only reached 1:2 (and 1:1 with the PK-3 extension tube).

this is no standard F mount =)
(as far as evaluating their specs goes - I meant MTF claims. The 55mm AF-D version may be the same optics - nikon didn't update several lenses when they went AF-D)
