When I'm shooting with old gear, older people often approach to tell me they are "glad to see one of those again." They then tell me how they or their relatives used to shoot with the same camera. They clearly are pleased, and even grateful, about what I am doing. I'm not sure what psychology is revealed here. Maybe a sense of continuity, of respect for something old that is nonetheless good. Whatever, people's reactions are so warm that they cheer up my entire day. I imagine people react the same way to old cars still on the road.
