The Canon RF 10-20mm f/4.0 L IS STM is a versatile ultra-wide-angle zoom lens specifically designed for Canon's EOS R series mirrorless full-frame cameras. With a focal length range of 10mm to 20mm, it is excellent for landscape, architecture, and interior photography. The built-in image stabilization (IS) allows for sharp images even in low light conditions or with longer exposure times.
The lens features an STM (Stepping Motor) autofocus system that provides fast and precise focusing. This is particularly useful when shooting videos, as the autofocus operates quietly and smoothly.

Being able to photograph with short focal lengths is essential in many subject situations. Just think of landscape shots where you want to cover as wide an angle of view as possible. Short focal lengths are also essential in architectural photography. In addition, you cannot change the angle at will by simply moving further away from the subject...
Despite the challenging focal length spread, the Canon RF 4/10-20 mm L IS STM delivers very good performance.
