Overview

The Komura 100 mm f/1.8 is a fast telephoto prime for 35 mm SLRs, known for its 18-blade aperture and preset ring. Its optical design resembles an Ernostar, earning it the nickname 'King of Ernostars'. No review excerpts provided optical strengths, weaknesses, or handling details. The lens suits collectors or enthusiasts interested in unique, fast vintage optics, but lacks sufficient data for a performance consensus.
