Designed for Canon’s RF-mount mirrorless full-frame cameras, the Canon RF 16mm F2.8 STM is a compact and lightweight ultra-wide lens for trekking, landscapes and architecture.

It features nine elements, one of which has an aspherical surface, all arranged in seven groups, and it employs Canon’s Super Spectra Coating to reduce ghosting and flare. The lens adopts a stepper-type (STM) AF motor for smooth and quiet focusing. It has a minimum focus distance of just 0.13 m (5.1″) and a maximum magnification of 0.26x.

Externally, the lens has a single control ring for manual focus or it can be allocated with another function from the camera, if desired. With a 43 mm filter thread, the lens is highly compact for a relatively ‘fast’ ultra-wide and it’s lightweight, weighing just 165 grams (0.36 lb).
