Hi all! I got an old Afga Karat IV for cheap and it seems to be working but I'm not sure about the rangefinder... It might be 'off'. Never having used such a camera before, I don't know how to tell for sure. Does anyone know? If it is in fact, out of whack, any easy way to fix it? What if I leave it set at infinity? Anyone else have one these gems? I'd love to hear about it. I love old cameras; They are oh so charming!
