For 42mm screw thread Pentax, Fujica, Mamiya, Ricoh, Vivitar, and Yashica single lens reflex cameras only (where a lens must be rotated through several complete turns before it attaches firmly to the camera body). Also known as the 42mm universal thread. Not for bayonet-style lens mount versions of these cameras (where the lens rotates only one-quarter of a turn and clicks into place). Needed to connect the above 35mm SLR camera bodies to a T-adapter or camera adapter for prime focus photography (full disc solar/lunar photography and terrestrial photography); to a tele-extender or camera adapter for eyepiece projection photography (planetary photography and close-up shots of the Moon); and to an off-axis guider for long exposure deep space photography.
