The Newman & Guardia Sibyl is a British-made folding plate camera produced in the early twentieth century. It was a compact-format hand camera aimed at advanced amateur and professional users when new.

Sales data for the Sibyl is sparse, with a recent UK auction hammer result of £100 in April 2024 — a wholesale saleroom level rather than a retail asking price. On that limited evidence, today's price for a Sibyl sits around the £100 mark, though condition, completeness of the case and accessories, and the specific variant can move the value materially.
