The Kodak Retina I (117) is a 35mm folding viewfinder camera, the first model in Kodak's Retina series introduced in the mid-1930s. It was positioned as a compact, precision-built camera using the then-new 135 cartridge, which Kodak launched alongside it.

Sales data for the Retina I (117) is extremely thin: only one UK auction-hammer result is on file, a sale at £170 back in 2005, so any current valuation is indicative rather than market-tested. As of today there is not enough recent saleroom evidence to state with confidence what a Retina I (117) sells for or is worth on the open market in 2026.
