Thanks, William, Brian, Bruce, Collin, JC, Mark and Joe, for your interesting and very informative posts.
I think I am leaning towards the Pentax D FA 100mm 2.8, but still thinking about it. Joe, I did quite a bit of work with extension tube when I used only my Asahi Spotmatic and my Honeywell Spotmatic. It was actually quite a bit of fun. I don't have either the eyesight or the patience to go back to extension tubes at this point in my life, however.. I think I need autofocus to get in the ball park before final adjustment in manual focus mode. Dan Matyola http://www.pentaxphotogallery.com/danieljmatyola On Sat, Dec 1, 2012 at 8:50 PM, J.C.
