Overview

The Olympus OM Zuiko Auto-Macro 20 mm f/2 is a specialized bellows macro lens for magnifications from 4.2× to 16×, with an automatic diaphragm and focusing helicoid. It offers excellent optical quality but requires significant setup: a sturdy tripod, focusing rail, and careful lighting due to a short working distance of 18–20 mm. The lens is beautifully crafted and compact, with a tapered profile to avoid blocking ring flash. It suits dedicated macro photographers willing to invest effort for unique high-magnification images.
