The Newman & Sinclair Kinema No.3 is a British-made professional cine camera, a type of motion-picture apparatus produced for the film industry rather than for amateur use. Newman & Sinclair was a London maker known for sturdy metal-bodied cine equipment aimed at professional cinematographers.

With only a single recorded UK auction hammer result — £780 at Christie's in 2007 — there is no meaningful price range to quote, and the value of a Kinema No.3 today is best treated as indicative rather than established. That figure reflects a wholesale saleroom result for one example sold nearly two decades ago, and current worth could differ substantially depending on completeness, condition and buyer interest when one next surfaces.
