The Voigtländer Perkeo I is a folding medium-format camera that shoots 6×6 frames on 120 roll film. It is a compact, bellows-type rangefinder-less folder from the post-war era, positioned at the affordable end of Voigtländer's roll-film line when new.

UK auction hammer results for the Perkeo I are thin and widely spread: recorded sales range from about £20 to £330, with the low figure reflecting a recent 2026 saleroom result and the higher figure an older Christie's hammer price. Because only two data points are available, there is no reliable median, and today's value for a given example depends heavily on cosmetic condition, bellows integrity, and whether the shutter is working; clean, functional bodies sell for meaningfully more than project cameras at auction level.
