How many times do I have to post it? Optimizing for digital and optimizing for format size are two different things, and I dont believe that the differences you are seeing in some of the DA lenses vs FF lenses of the same focal lengths are due to digital optimization, they are due to Format optimization. (DA lenses, designed to cover only 2/3 the angle or 45% of the area of a FF sensor, can be made to perform slightly better ONLY ON THAT SMALL AREA, then a lens which has to cover it all.
Digital optimization will become more of an issue for SOME FF lenses when the FF sensor is used, but for now, the limited angle of coverage being used with FF lenses on APS cameras is not bringing digital optimization much into play IMHO. jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, February 08, 2007 1:20 PM To: Pentax-Discuss Mail List Subject: RE: NO FS this Friday?

Dag, Godfrey and myself all seem to have experienced something that disagrees with you regarding film optimized lenses though. Pentax and the other lens manufacturers seem to think lenses need to be optimized for digital as well. I suppose you are saying screw you to their optical engineers too? You don't know anywhere near as much as you think you do on this subject. Continue blowing hard though, you definitely know more about doing that than I do.
