    Overview

    The Helionar-1 85 mm f/1.4 MC is a rare, ultra-fast portrait prime for Pentax K mount, later renamed MC Zenitar-1K. It features achromatic multi-coating. No review excerpts provide details on optical strengths, weaknesses, or build/handling. The lens is described as very rare and expensive. Without performance data, it is difficult to assess suitability, but its fast aperture suggests use in low-light or portrait photography.
