The Rollei 2.8GX is a medium-format twin-lens reflex camera taking 6x6cm frames on 120 roll film. It sits in the later production run of the Rolleiflex 2.8 TLR series and was offered as a working photographer's tool rather than a budget option when new.

Sales data for the 2.8GX is thin, but a recent UK auction hammer result of £1,600 in November 2025 gives a working reference point for what a clean example sells for at saleroom level today. With only one verified sale to draw on, the wider price range is not yet established, and condition, completeness of accessories and cosmetic wear are likely to swing the value materially either side of that figure.
