The Gallus Derlux is a French-made 35mm viewfinder camera produced in the post-war era. It was sold as a compact everyday picture-taker rather than a professional instrument.

With only a single hammer result on file, the Gallus Derlux is a thin market: the most recent UK auction sale price was £88 in February 2026. Today that figure is the only firm anchor for what a Derlux is worth at saleroom level, and individual examples can sell for more or less depending on cosmetic condition and whether the shutter and rangefinder still function.
