The Koni Omega Rapid-M is a medium format rangefinder camera designed for 120 and 220 roll film with interchangeable backs. It was built as a press and professional camera, offering 6x7 negatives and a coupled rangefinder for hand-held work.

At recent UK auction, hammer prices for the Koni Omega Rapid-M have spanned roughly £81 to £180, with the limited sample pointing to a midpoint near £130. As of 2026 the market remains thin and condition-sensitive, so what a given example sells for today depends heavily on the working state of the shutter, rangefinder and film back.
