The Canon RF-S 10-18mm F4.5-6.3 IS STM is a compact, lightweight ultra-wide zoom lens designed for APS-C format Canon RF-mount mirrorless cameras. With a focal length range of 10-18mm (equivalent to 16-29mm on full-frame), this versatile lens excels across landscape, interior, architectural, vlogging, and travel photography. The optical design features two Ultra-Low Dispersion glass elements and an aspherical element to deliver sharp, high-quality imagery from centre to edge while minimising aberrations. Built-in optical image stabilisation provides up to 4.0 stops of shake reduction (or 6 stops with compatible in-body stabilisation), and the STM autofocus motor delivers smooth, nearly silent performance ideal for video work. At just 150g and featuring a lens retraction mechanism, it is Canon's smallest and lightest ultra-wide zoom offering exceptional portability. The lens accepts 49mm filters and works seamlessly with both APS-C and full-frame Canon EOS R-series bodies.
