Read our notes on general
The Canon RF 10-20mm F4 L IS STM offers a unique zoom range providing impressive image quality that easily matches prime lenses. This is the world's first rectilinear zoom lens with a 10mm focal length and autofocus. Comparatively compact and lightweight, it delivers excellent build quality as a professional L-series lens. The lens requires digital correction due to massive distortion and vignetting at 10mm, but with auto-correction, vignetting becomes moderate and distortions negligible.
