My camera's are:
120's: Pentax 645, Yashica-Mat LM (circa '58)
35's: Canon Elan 7ne, Canon G-2, Canon K-2, GAF (Konica-circa '72), Kodak Retina (circa '51)
Pinhole: Holga, Homemade
I use all my old camera's on a regular bases and I keep them in perfect condition, they still take wonderful photographs.
Though I do get looks when I bring the Kodak or the Yashica out.
