I get a lot of attention, almost all of it positive, when shooting with my Yashicamat. People do ask about two lenses. The oddest was "what's up with that camera?" "Um, what do you mean?" "Why does it have two lenses?" "One's a viewing lens, one a taking lens. The top one sends the image to the ground glass you look down at to compose the image, the bottom one sends the image to the film." Truth is always better than a flippant lie, IMHO. "Oh ok" was the only response.
One friend asked, "it doesn't have batteries or any electronics for this?" commenting on the bright ground glass image. "Nope. Has a battery for the meter but I rely on a separate handheld meter most of the time." That lead to a discussion of what a light meter was and how modern cameras usually have them built in etc.
