The Zeiss Ikon Contaflex I (model 861/24) is a 35mm leaf-shutter SLR introduced in the mid-1950s. It was positioned as a fixed-lens reflex aimed at amateur photographers who wanted SLR viewing combined with the reliability of a between-the-lens shutter.

Auction data for the Contaflex I 861/24 is thin: a single UK saleroom hammer result from 2004 sold for £130, so a current market median cannot be reliably established for today's market. Buyers researching what a Contaflex I is worth in 2026 should treat that figure as a historic auction-hammer reference (wholesale, pre-commission) rather than a guide to what the model now sells for, since condition and working order drive most of the price.
