The Mamiya Press 23 is a medium-format press camera using interchangeable lenses on the Mamiya Press mount. It is a rangefinder-style body designed for professional press and studio work, capable of producing 6x9 negatives on 120 roll film.

With only one recorded UK auction hammer result, the Press 23 has limited public price data — a body sold for £180 in 2017. Given the auction-saleroom context (wholesale levels, before commission), today's value is hard to pin down without further results, and pricing in 2026 is highly condition- and lens-dependent. Buyers asking what a Press 23 is worth should expect any current sale price to vary materially based on whether a usable lens, rollfilm back, and viewfinder are included.
