The Rolleiflex 3.5 F Model 3 is a medium-format 6x6 twin-lens reflex camera from the Rolleiflex 3.5F series, taking 120 roll film. It belongs to the line of professional TLRs Rollei produced in the 1960s, positioned at the upper end of the amateur and working-professional market when new.

At UK auction, hammer prices for the 3.5 F Model 3 have ranged from £390 to £730, with the two recorded sales sitting either side of a £555 midpoint — note these are saleroom wholesale results rather than dealer retail. As of 2026 the sample is small, so what a given example is worth today depends heavily on cosmetic condition, lens clarity and whether the meter and shutter are working; clean, fully functional bodies sell for more than cosmetically tired ones.
