Yashica D uses Bayonet 1 ( Bayonet 30 ) accessories. Plastic lens hoods and filters are available, hoods are cheap, filters no so cheap. These are not fragile cameras, but are somewhat quirky. Don't change shutter speeds after cocking shutter, don't use self timer with flash selectot on M are about the only things to remember, except maybe when advancing film, just push the button on the winder knob then let it go before winding film. The instructions are available from Butkus on line. Buy the durned thing and have a blast shooting it.
