The Rolleiflex 6003 Professional is a medium format SLR using 6x6 roll film, part of Rollei's 6000-series system introduced in the 1980s and 1990s. It was positioned as a professional studio and location camera with motorised film advance, electronic shutter control and interchangeable backs and lenses.

At UK auction in recent years, hammer prices for the 6003 Professional have sat between roughly £450 and £550, with the two recorded sales giving a midpoint around £500. As of today the sample is thin, so condition, completeness of back and finder, and inclusion of a working battery grip materially affect what a body sells for at saleroom level.
