I've not had much time to play with my 21 Elmarit, but I will try to give it some play this weekend. Over the years, I've collected a number of interesting lenses, some Leica, some Nikon, Pentax, and some other old-timers that I would like to play with. I had limited fun with my little Olympus, but it obviously cut off most of the frame of everything but my 16mm lenses. The cheap adapters available on Amazon, along with free Prime shipping makes his kind of shooting fun again. 50 some posts on this thread, and I'm the only one who posted a picture. Thanks Jay, for the ONLY comment. ;-) On Fri, Feb 21, 2014 at 9:00 AM, Steve Barbour <steve.barbour at gmail.com>wrote: > > On Feb 20, 2014, at 5:46 PM, Jim Laurel (gmail) <jplaurel at gmail.com> > wrote: > > > All I've seen, Steve, is some anecdotal evidence.
