The Kuribayashi Petri 2.8 is a 35mm viewfinder camera from Japan's post-war camera industry, produced by Kuribayashi Camera Industry (later renamed Petri). It was sold as an entry-level fixed-lens 35mm rangefinder/viewfinder model with a moderately fast f/2.8 lens for the consumer market of its era.

The single UK auction record on file is a hammer price of £44 in May 2025, so today's market value sits at the lower end of the vintage Japanese 35mm bracket. With only one saleroom result to draw on, what a Petri 2.8 sells for in the auction market depends heavily on cosmetic condition and whether the shutter and rangefinder are working.
