The Newman & Guardia Longfocus Reflexkamera is a British-made plate reflex camera from the early twentieth century, built by the London maker Newman & Guardia for long-focus photographic work.

Data on what this model is worth today is thin: a single UK auction hammer result from February 2024 saw an example sell for £106. With only one recorded sale at saleroom level, there is no meaningful range or median to quote, and the price a comparable example sells for in 2026 will hinge heavily on bellows condition, completeness of the reflex mirror and ground glass, and the presence of any original lens.
