The Lennor Delta Stereo is a stereo film camera that produces paired images for three-dimensional viewing. It is an uncommon model that surfaces only occasionally on the collector market.

Sales data for the Delta Stereo is extremely thin: a single recorded UK auction hammer result of £100 (2007) is the only reference point for what this camera is worth, so any current price estimate is provisional. Today a clean, working example would likely sell for a figure in that region at saleroom level, but with only one data point the true market value is hard to pin down.
