The Olympus Auto Bellows can be used with various units of the OM System for almost every kind of macrophotographic work. The extension range is 36 to 198mm.
The aperture iris diaphragm built into the lens can be stopped down either simultaneously with the shutter release by using a double cable release, or prior to the exposure by using the preset lever of the unit.
Item is in perfect working order and very good cosmetic condition.
