I just can't help but think I need a Leica 35mm SLR in my life particularly either an R5 or R7, do any of you fine people have any experience with these cameras? I've found a site specialising in Leica's based I think, in Switzerland who ship world wide and their stock seems to be in great condition. So, before I start saving is there anything I should know about them? Are they reliable, do the mentioned models have any issues at all? Your advice would be greatly appreciated, thank you.
