This sale is for a near mint condition Mamiya 645 Connector N.
This connector is normally supplied with the 645 Super Left Hand Grip – but is really easy to lose. Even without using the grip (which will not work properly without this connector) it is still a handy thing to have as it allows use of a standard cable release and also gives you a standard flash sync socket. Extremely hard to find.
This connector has minimal signs of use. Please note that it is NOT usable with the 645 ProTL; this camera needs a different connector (code RA402).
