The Canon IIS is a 35mm rangefinder camera with a Leica-style M39 screw mount, produced by Canon in the 1950s. It was positioned as a mid-range update within Canon's screw-mount rangefinder line, aimed at serious amateurs and working photographers of the period.

Evidence for what a Canon IIS is worth today is thin: only a single recorded UK auction hammer result of £230 (from October 2023) is available, so a reliable median or range cannot be quoted. Buyers asking how much a Canon IIS sells for in 2026 should treat that figure as a rough anchor rather than a firm market value, since saleroom prices vary widely with cosmetic condition, rangefinder accuracy and shutter health.
