The Canon Serenar 50mm f/1.8 is a standard prime lens in Leica L39 screw mount (LTM), produced under Canon's pre-FD Serenar branding for rangefinder bodies. It is a fast normal lens from the early post-war Japanese rangefinder era, designed for use on Canon and Leica thread-mount cameras.

UK auction data for this Serenar is thin: a single hammer result of £56 in January 2025 is the only verified saleroom price on record, so the working value as of today sits at the low end of the screw-mount fifty market. Because that figure is a hammer price achieved in the UK auction market — wholesale, not a retail asking — clean, haze-free copies offered through dealers typically sell for more, while heavily fungused or scratched examples can fetch less. With only one confirmed sale, the lens is best treated as having a thin and uncertain price band rather than a settled market value.
