I guess I wasn't clear enough, the DAs do a similar or better job than many FF lenses, but ONLY on APS cameras. Point is when you go to full frame, a lens only has to be 2/3 as sharp as a DA lens is in lp/mm resolution to match the DA lens on APS for resolution. And I bet there are a whole bunch of PK FF lenses out there that are more than 2/3 the sharpness of the best DA lenses in existance. These lenses will work better on full frame than the best DA lenses on APS in terms of final image resolution. I hate to use the expression, but DA lenses are kinda like "turd polishing", yes they squeeze the most possible out of APS format but will never match what is/will be possible with full frame with even lower optical quality lenses that have more than 2/3 the resolution of the best DA lenses.

I don't get this. What matters (for me) is that the DA does a similar or better job. The reasons why they do are as interesting as the popes new beard IMO.

I think you are mistaken because full frame lenses only need to have 2/3 the resolution to MATCH/BEAT DA lenses in terms of overall resolution. you guys act like pentax and everybody else just discovered how to make fine lenses and that all the old FF ones on FF cant beat best new DA ones on aps. I say that on full frame some of them can and will BEAT the best APS lenses on APS due to the format size difference alone. jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Stenquist Sent: Saturday, February 03, 2007 6:22 PM To: Pentax-Discuss Mail List Subject: Re: NO FS this Friday? I'm talking about the DA 12-24, which is a very fine optic and probably better than both the K and A 15 primes.The DA 14/2.8 is almost certainly even better. I'm also talking about the upcoming DA* lenses, which may well be better than any of the FA lenses ever produced. They will certainly be better performers in terms of autofocus. The past is history.
