The RB mount which is a bayonet type system with a locking ring. Lenses are equipped with Seiko leaf shutters and focus is set on the camera body using a bellows arrangement with a 46mm extension. The click stops can be at half-stop aperture settings, but the shutter speeds can only be set at full stops. A depth of field preview lever is also built-in to the lens. The lenses typically have shutter speeds of 1 to 1/400 of a sec. and a T mode. The T mode, keeps the lens shutter open until the shutter ring is moved onto the 1 sec mark or when the shutter cocking lever is pressed slightly. Since it’s a leaf shutter based camera, electronic flash sync is available at all speeds. Since the system is synchronized, the camera body and lens must be cocked before attaching or removing the lens. To cock the lens ensure that the pins are in-line with the red indicators. A majority of the lenses use a screw on 77mm filter making it much easier to swap filters between lenses.
