The Kodak Retina IIIs (027) is a 35mm rangefinder camera with interchangeable lenses, part of Kodak's German-made Retina line produced in Stuttgart. It was introduced in the late 1950s as a fixed-body alternative to the folding Retina IIIc/IIIC, accepting a range of bayonet-mount lenses.

Auction data for the Retina IIIs (027) is thin: a single UK hammer result of £300 is recorded from 2022, which gives only a rough indication of value at saleroom level rather than a reliable range. Today, condition, working shutter and meter, and the presence of original accessory lenses are the main factors that decide what a IIIs sells for at auction. With so few data points, anyone asking what a Retina IIIs is worth in 2026 should treat that £300 figure as one example rather than a market median.
