Olympus OM Auto Bellows brand_Tamrac with a roughly 20cm runThis Olympus Auto Bellows is a sturdy macro bellows with a built in focusing rail for OM lenses and bodies. In excellent cosmetic condition, with only light finish wear. Bellows are intact. The lever actuated "auto diaphragm" stopdown is a touch sluggish to return, but it gets there eventually, and there's no effect on manual mode in any event. Includes original box.
