The Canon IVSB is a 35mm rangefinder camera using the Leica screw mount (M39), produced by Canon in the early 1950s. The black-finish version is a less commonly encountered variant of a body more usually seen in chrome.

Auction data for the black IVSB is thin: the two recorded UK saleroom hammer results sit at £164 and £253, giving a narrow range of £160–£250 with a median around £210. As of 2026 these older results should be treated as indicative rather than a current price guide, and condition together with the black-finish variant premium will heavily influence what a clean example sells for today at auction.
