The Rolleiflex 3003 de Lux is a 35mm SLR produced by Rollei, a deluxe variant of the modular 3003 system body. It was positioned as a high-end professional 35mm camera within Rollei's lineup.

Sales data for the 3003 de Lux is extremely thin: a single UK auction hammer result from 2011 recorded the camera at £1,200, reflecting the wholesale saleroom level rather than a retail asking price. With only one data point on file, today's value should be treated as indicative only, and what a clean example sells for now will depend heavily on completeness of the modular system, cosmetic condition and whether original accessories accompany the body.
