At f2.8 the Apo ASPH is better, and at f2 it wins hands down ;-) These are just my opinions, for scientific tests go to Erwin's site. The Apo ASPH will block a very small portion of the 90mm frame on your M6HM. Focused at infinity it is just a small part of the lower right hand corner. Focused at the minimum focusing distance this increases, but still remains very acceptable. This is with the hood extended.

Also, would the APO one block the 90mm frameline of the viewfinder ? I am currently using M6 HM.. :) Regards. - --------------------------------- Do You Yahoo!? Send online invitations with Yahoo!
