==== Summary ====
The RF10-20mm F4 L IS STM is a unique ultra-wide-angle lens that gives you corrected, rectilinear coverage to an incredible 10mm with full-frame cameras. Great for still photography and videography, the 10mm ultra-wide-angle effect is outstanding for its dramatic look, lending visual drama to your landscape, interior, architecture, travel, and even photojournalism images. This lens features true L-Series quality with optical and digital corrections for distortion, and optical image stabilization (OIS) for better low-light performance, especially when shooting video. Autofocus is handled by a tried-and-true STM-type focus motor which actually allows the overall lens design to be more compact while still providing rapid AF and smooth focusing during video recording.
