The Rolleiflex 3.5 E3 is a medium-format twin-lens reflex camera using 120 roll film, produced by Rollei in West Germany. It sits within the 3.5 E-series line introduced in the late 1950s and early 1960s, positioned as a professional roll-film TLR aimed at studio and reportage photographers.

UK auction hammer prices for the Rolleiflex 3.5 E3 have ranged from around £420 to £560 across the limited records available, with a median near £490. Because only two saleroom results inform this picture, the figures are indicative rather than definitive, and condition of the taking lens, shutter accuracy and finder brightness drive most of the variance seen in the market today.
