Robert, I'm glad to hear your "hands on" experience with the 80mm f2.8 Meogon. I also like the fact that it was a positive one at that. You also answered a question I had the was swirling around in the back of my head. That is using it for macro/micro close-up work. I have a LTM(39mm) to M42 adapter and a helical focusing M42 extension tube that I use I my Canon 5D and thought if nothing else that this lens would make a very good macro lens for easy focusing at f2.8. Sounds like this lens will be an interesting toy to play with. JohnW
