Bloch Physiograph Stereo
The Bloch Physiograph Stereo is an early stereoscopic camera produced by the French maker Bloch. It records paired images for stereo viewing and is encountered today as a collector-grade antique rather than a working user camera.
At recent UK auction, hammer prices for the Bloch Physiograph Stereo have spanned roughly £1,200 to £4,500, with a median around £1,500 based on the limited saleroom record available. As of today the model trades thinly, so what one sells for in 2026 depends heavily on completeness, cosmetic condition, and whether original accessories accompany the body — the £4,541 result from 2004 sits well above the more typical four-figure outcomes and reflects how much variant and provenance can shift value.
