With the recent discussions on the 45mm, which everyone seems to appreciate, I wonder why the 55f/4 is the more expensive lens. I have the 55 and have always wanted the 45, or so I thought. Any easy explainations? I had the 55f/3.5 but wasn't thrilled with the results, except for the viewfinder brightness. - This message is from the Pentax-Discuss Mail List.
