Canon 100mm f/4

The Canon Serenar 100mm f/4 is a short telephoto rangefinder lens in Leica 39mm screw mount (L39/LTM), dating from Canon's early post-war rangefinder era before the company standardised on the 'Canon Lens' branding. It was designed as a compact portrait and medium-distance optic for Canon and Leica thread-mount rangefinder bodies.

At recent UK auction, clean examples typically sell for between £25 and £70 at hammer, with a median around £45 — these are saleroom results (wholesale, before commission) rather than dealer asking prices. Through 2024 and into today the Serenar 100mm f/4 remains one of the more affordable Canon rangefinder lenses, and its value has held steady in that band; a boxed or exceptional-condition example achieved £500 in a specialist Leitz sale back in 2016, showing what the very best copies are worth when presentation matches condition.

How much does a Canon Serenar 100mm f/4 sell for in top condition?

Ordinary clean copies top out around £70 at auction, but an exceptional example in a specialist Leitz sale reached £500, so presentation and provenance can move the price sharply.

Will the Serenar 100mm f/4 fit a Leica?

For a vintage Canon rangefinder telephoto with Leica thread compatibility, the price range is modest and the lens offers an affordable entry point into LTM shooting, provided the glass is clear and the focus is smooth.
