    Overview

    The Sun YS-85 85-210mm f/4.5 is a vintage zoom lens from the 1970s. It is unlikely to contain thoriated glass, as that was not used in that era (D1N0). Optical strengths are not detailed, but the lens is described as 'fun' by a user (Doetuck). Weaknesses are not explicitly mentioned. Build and handling are not discussed. The lens suits enthusiasts of vintage manual-focus lenses who enjoy its retro character and are not seeking modern optical performance.
