The Cosina 19-35mm f/3.5-4.5 MC Zoom is a third-party wide-angle zoom lens with a variable maximum aperture of f/3.5 to f/4.5 and multi-coated optics. Cosina produced this design in several mounts during the autofocus SLR era, where it was aimed at amateur photographers wanting an affordable ultra-wide to standard-wide zoom range.

Auction data for this lens is extremely thin: the only verified UK saleroom record we have is a hammer price of £12 in March 2023, which gives a single data point rather than a meaningful range or median. As of today in 2026, that result suggests clean copies sell for very modest sums at auction, and because hammer prices reflect wholesale levels achieved in the saleroom, retail dealer asking prices will typically sit higher. Without further sales it is not possible to confirm whether specific mount variants command any premium.
