Hi all, looking at some peoples gear signature many have what I assume to be off brand older lenses. I decided to get an m42 to canon adapter, I may yet pick up a contax to canon also. There are hundreds of m42 cheap lenses on ebay but its like a bowl of spagetti, where do you start. I don't particularly need any specific type of lens but thought that it might be interesting if some of the more experienced could recommend some older lenses that one may be able to pick up for a bargain. I think a Yaschica 135mm f2.8 will be my first experiment with this as it looks like it could be a really nice portrait lens. What do you recommend?
