The Rolleiflex 6001 Professional is a medium format SLR taking 6x6cm images on 120 roll film, part of Rollei's modular 6000-series system aimed at studio and professional use.

UK auction data for the 6001 Professional is thin, so a reliable price band cannot be drawn today; the single recorded hammer result sits at £550, achieved at saleroom level (excluding commission). Until more sales appear, that figure is best treated as an indicative data point rather than a market median, and what a 6001 sells for in 2026 will hinge heavily on whether the body is bundled with a lens, magazine and finder.
