Out of curiousity I checked the 25mm APO Hyperprime and 25mm APO Microprime specs on SLR Magic's site and it seems there are at least some differences in lens construction and amount of diaphgram blades. Also the Microprimes cover a slightly larger image circle?

Same discrepency with the 32, and the APO has a shorter MFD

Build looks nicer on the Hyperprime, as well as having that PL or EF choice.
