The Newman & Guardia Sibyl Deluxe is a British folding rollfilm camera, a higher-grade variant within the Sibyl family of compact folding plate and rollfilm cameras produced by the London maker in the early 20th century.

Sales data for the Sibyl Deluxe is thin: a single UK auction hammer result from May 2020 saw one sell for £294, which is the only verifiable saleroom data point we have on what this camera is worth today. With just one record there is no meaningful range or median to quote, and condition, completeness of the original case and accessories, and working shutter all heavily influence what a given example sells for at auction.
