The Canon Serenar 85mm f/1.9 is a short telephoto rangefinder lens in Leica L39 screw mount, dating from Canon's pre-FD rangefinder era. Designed as a fast portrait-length optic for Canon and Leica screw-mount bodies, it predates the 1971 introduction of the FD system and sits among Canon's early post-war Serenar-branded lenses.

At recent UK auction, hammer prices for the Serenar 85mm f/1.9 have ranged from £100 to £140, with a median around £106 based on three recorded sales between 2023 and 2025. As of today in 2026, that places the lens in the entry-level collectible bracket for Canon L39 glass, and clean, haze-free examples tend to sell for the upper end of that range while cosmetically tired copies sit near £100. Condition, glass clarity and the presence of the original finder or caps are the main factors moving what this lens is worth in the saleroom.
