The Olympus Pen D2 is a half-frame 35mm viewfinder camera from the Olympus Pen series, part of the compact half-frame line Olympus introduced in the late 1950s and produced through the 1960s. Sold as a fixed-lens compact, it produces two 18×24mm exposures per standard 35mm frame, doubling the shot count of a conventional roll.

Sales data for the Pen D2 is very thin: the one recorded UK auction hammer result in our history sold for £50, so any sense of what this camera is worth in 2026 has to be drawn from that single saleroom data point rather than a true range. As a guide to value, expect clean, working examples to sell for similar low double-digit figures at auction, with condition and meter function being the main factors in what a Pen D2 sells for.
