Your shot looks very nice and sharp, Don. Even in the corners/edges. Amazing clouds! I've been studying my test shots a little closer. (I tested all my lenses wide open and at f2.8 - f4- f5.6 and f8 - all the talk about the Limited lenses started this). The Tamron Adaptall 28mm has better/higher contrast, thus appears to be sharper. But the A 2.8/28mm actually render better resolution/richness of distinguishable detail. I guess a lens maker considers the Pentax-A 2.8/28mm a better lens, even though it appears less sharp/contrasty. So, for low contrast subjects I may use the Tamron. Where high resolution/fine detail and subtle colours is required, I'll use the Pentax, which actually is a nice walk-around lens for the *ist D. I'm glad I finally got the focusing helicoids adjusted :-)
There's a SMC Pentax-F 17-28mm Fisheye f/3.5-4.5 up for auction at ebay (USA only). Would this give a lot of distortion on a "D", do you think? I have become increasingly fond of F-lenses. They are really better built than they look. I only have two and one AF adapter. They just work and work and work. And seem a lot better, than the rather toyish design suggests! Look at the 50mm range of the F 4-5.6/35-80mm (@ F4 and F5.6)comparede to FA 1.4/50mm and M 1.7/50mm: http://gallery37564.fotopic.net/p13454735.html All the best Jens Bladt mailto:[EMAIL PROTECTED] http://hjem.get2net.dk/bladt -----Oprindelig meddelelse----- Fra: Don Sanderson [mailto:[EMAIL PROTECTED] Sendt: 4. april 2005 21:27 Til: pentax-discuss@pdml.net Emne: RE: (Hey Jens) Pentax-A 2.8/28mm Here's a sample from the A28/2.8 on Superia 400.
