I like shooting with my three Leica R lenses, Elmarit-R 28 2.8, Summicron-R 50 2 and Macro-Elmar-R 100 4. Yes, they are heavy chunks of glass, and they do take a little extra effort to use. But, I really like the results that I get with them. Going back through my pictures, I find that some of my favorite images where taken with one of these lenses. It doesn't really seem that anyone else on the forum is using Leica R glass. I realize that Leica stuff is pretty over-priced, but some of the older Leica R lenses are not extravagantly expensive on KEH or MPB. I just don't find many instances of people user Leica R on m4/3 much anywhere, and just a few instances of people using them adapted to other digital cameras (Canon, and other Leica cameras.) Even @Amin Sabet's Leica forum doesn't have much traffic for Leica R. I was wondering if anyone knew of a place online that could be a good resource, but more importantly, that has an active user group. I am looking for first hand knowledge with the glass and a place to share what I produce.
