90–190mm · f/5.8
The Yashica Yashinon-R 90-190 mm f/5.8 is a consumer-level zoom lens from the 1960s, offering fair image quality with notable edge sharpness issues. Its build is basic, and handling is less convenient than modern zooms. The lens features a unique Pentamatic bayonet mount, limiting compatibility. It suits vintage camera enthusiasts interested in Yashica's history, particularly those who prioritize period authenticity over optical performance.
