The Contax 28mm f/2.8 Distagon is a Carl Zeiss-designed wide-angle prime for the Contax/Yashica (C/Y) bayonet mount, used on Contax 35mm SLR bodies such as the RTS series. Distagon is Zeiss's retrofocus designation for SLR wide-angles, and this lens was aimed at general reportage, landscape and architectural work where a moderate wide field and a relatively compact body were both wanted.

Sales data for this reference is thin: a single UK auction hammer result of £162 in April 2023 is the only verified data point we hold, so a meaningful range or median cannot yet be quoted. As of 2026, that figure should be read as a wholesale saleroom price for a usable copy, and clean, fungus-free examples in C/Y mount can sell for more at retail; what a Contax 28mm f/2.8 Distagon is worth on any given day will depend on cosmetics, glass condition and whether a hood and caps are present. Buyers asking how much one sells for should treat £162 as an indicative auction-level data point rather than a firm market price.
