Best Sigma Landscape Lenses Under £800 in 2026

Its bright f/1.4 maximum aperture, lightweight 250g build, and weather-sealed body deliver a 19.2mm full-frame equivalent field of view, making it a standout ultra-wide APS-C prime. The stepping motor AF provides quiet, precise focusing with minimal breathing, complemented by water- and oil-repellent coatings and dust/splash-resistant construction for reliable outdoor use. This lens is best for Canon RF APS-C shooters needing a compact, fast ultra-wide for vlogging, low-light interiors, and close-up landscape or street work.
