The Houghton Ensign Focal Plane Rollfilm Reflex is a British rollfilm single-lens reflex camera produced by Houghton. It is a waist-level reflex housing a focal-plane shutter, sold to advanced amateurs and press users in the early 20th century.

Sales data for this model is extremely thin: a single recorded UK auction hammer result of £37 from January 2022, with no later confirmed sales to establish a reliable range. On that basis the camera sells for low double-digit figures at saleroom level today, but the value of any individual example in 2026 will depend heavily on cosmetic condition, shutter function, and completeness of the original lens and back.
