The magnitude of vignetting is not that great, maybe a stop at very most, so its not a big deal as far as limiting dynamic range.
35mm IS a wide angle lens by any standards on FF 24x36 format. Wide angle covers about anything less than 40mm on that format. And I dont beleive there are no other pentax wide lenses that would not work as well or better on FF digital as the necessary shorter lenses do on APS digital. Anyone know anyone whos used them that way? ( maybe that guy whos using them on Canon digital?) jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Margus Männik Sent: Tuesday, January 02, 2007 5:10 PM To: Pentax-Discuss Mail List Subject: Re: More rumors ... (and happy New Year) 35mm is technically speaking a wide angle, but IRL it's not quite a wide. At least not for my kind of photography. OK, it's a bit individual. Vignetting can NOT be so easily corrected without loss on density range (photographic latitude). But, yes, the loss of resolution is the main problem. I do agree - generally - the smaller the frame, the better correction technologies have to be used. However, digital sensor introduces it's own limitations and if we summarize lens + sensor (+other technical limitations), today digital FF wide-angle digital FF is still bigger problem than Digital APS wide-angle.
