The Ernemann Stereo-Reflex is an early 20th-century German stereoscopic plate camera built around a reflex viewing system, intended for paired-image photography on glass plates. Ernemann, based in Dresden, produced specialist apparatus of this kind before the company was absorbed into Zeiss Ikon in 1926, placing the Stereo-Reflex among the pre-merger output of an established German manufacturer.

Auction evidence for the Stereo-Reflex is thin: a single UK saleroom hammer result of £600 is on record from 2005, so any present-day value estimate carries wide uncertainty. As of 2026, what one of these sells for at auction today depends heavily on completeness, plate-back condition and shutter function, and a clean, working example would likely be needed to approach or exceed that historic figure. With only one verified hammer price (wholesale, exclusive of commission), buyers and sellers should treat the worth of this camera as condition-led rather than catalogue-driven.
