Overview

The Olympus OM Zuiko 135mm f/4.5 Macro is a unique bellows-mount lens requiring the Auto Bellows or Telescopic Auto Tube. It offers a long working distance and focuses to infinity, but handling is clunky due to dual focus controls. Optically, it delivers impressive results even at f/45, though achieving pinpoint focus can be challenging. It suits still-life and tabletop photography, but its awkwardness limits field use.
