The Olympus Pen D is a half-frame 35mm viewfinder camera from the Olympus Pen family, introduced in the early 1960s. It was positioned as a higher-specification model in the line, fitted with a built-in selenium meter and a fast fixed lens for compact everyday shooting.

At UK auction today, hammer prices for the Pen D have been modest, with recent results sitting between £25 and £40 — wholesale saleroom levels rather than dealer retail. With only two recorded sales, the median value sits around £33, and what a Pen D sells for is heavily condition-dependent: a working meter, clean lens and smooth shutter lift prices toward the upper end.
