I dont have any medium format lens tests in my bookmarks but I saved this one a while back:
http://www.hevanet.com/cperez/testing.html These are some of the worlds finest and some very expensive 4x5 LF lenses. I dont see any that match 35mm's best or even Pentax's best 35mm lenses. This contradicts your "all really good lenses are essentially the same with regards to absolute resolution" theory. There is nothing to suggest that MF would be exactly like 35mm but then somehow everything changes when you reach LF lenses. I say generally the MF lenses fall somewhere in between the 35mm and LF lenses in terms of absolute resolution based on these things and also based on experience. I am not exactly sure why it's this way but it sure seems to be the case... jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of William Robb Sent: Sunday, December 10, 2006 11:14 PM To: Pentax-Discuss Mail List Subject: Re: Pentax 645D Sensor size(?) ----- Original Message ----- From: "J.

So you didn't bother to look at the resolution numbers for the Hassy, Rolleiflex and Mamiya lenses I take it? They appear to be every bit as high as those for the 35mm lenses from Pentax. Not that I would expect an admission or anything.
