In Coimbra Portugal, I encountered a few photographers using rangefinders. Two had what looked like FSU rangefinders, one a Yashica and one had a Canonet. I had the opportunity to have a nice talk with the Yashica user. I didn't approach the others as I spotted them from a distance.
I never ran into any photographers using rangefinders 'in the wild' here in Sault Ste. Marie Canada but I know two local photographers that shoot with rangefinders; CapitalK above and another good friend and co-worker named John. I first met John the day he was hired as a teacher. The principal of my school brought him up to my classroom to introduce him to me since we had a common interest in photography. I asked him what he used and he said that he used a film camera made by this great, old company that I probably never heard of; a company called Leica. I then reached inside my bag, pulled out my MP and asked "Something like this?". You should have seen the look on his face. At the time, John thought he might be the only Leica shooter in our town. I thought that about myself too. Since then, CapitalK got an M5 and I've also encountered a Leica R8 shooter.
