Mentor Goltz & Breutmann Mentor Dreivier

The Mentor Dreivier is a small-format reflex camera produced in Dresden by Goltz & Breutmann. Its name refers to the 3×4 cm negative format it was built around, positioning it as a compact alternative to the larger plate reflexes common in the German market between the wars.

At recent UK auction, hammer prices for the Mentor Dreivier have ranged from around £380 to £1,700, with a median close to £800 across the five saleroom results on file. The spread is wide because condition, completeness of plate holders and accessories, and variant differences drive what each example sells for — a clean, working body with original fittings is worth considerably more in 2026 than a tired example offered as a display piece.
