The Contessa Ergo is an unusual rangefinder-style camera distinguished by its right-angle viewing prism, which lets the photographer shoot at 90 degrees to the subject. It is a niche collector's item rather than a mainstream production model, and survives today largely in the hands of specialist collectors.

Auction evidence for the Contessa Ergo is thin, but the two UK saleroom hammer results on file span roughly £1,000 to £2,400, with a midpoint near £1,700 — figures that reflect wholesale auction levels before buyer's premium rather than dealer retail. As of 2026, what a Contessa Ergo is worth today depends heavily on completeness, cosmetic condition and the presence of original accessories, and the small sample size means any individual example could sell for materially more or less.
