The Ihagee Night-reflex (Nachtreflex) is a pre-war German plate-format reflex camera built by Ihagee of Dresden, designed for low-light work with a high-speed lens. It is a scarce specialist instrument from the early decades of the twentieth century rather than a mass-market model.

Auction evidence for the Night-reflex is thin: the two recorded UK saleroom hammer results sit at £8,000 (2016) and £35,625 (2002), so any sense of what one is worth today rests on a very small sample of wholesale auction prices rather than retail asking levels. Condition, completeness of the original lens, and provenance drive value, and a single strong sale can reset expectations for what the next example sells for.
