Whew, am I glad you found an m5. I have two and was thinking of selling one of them because it seems to stay home more than my other m's. I also had Sherry give my black one a make over and it came back working like the day it left wetzler.
I was shooting with one last weekend in the north end of central park and a group of neighborhood kids came over and asked, "man, how old is that camera?" about 30 years old, I replied. One kid said "Does it use film? I bet it doesn't even have a battery."
Another said it looked like a security camera. Of course I took their photograph.
anyway, enjoy it.
