While the Canon RF 10-20mm F4L IS STM is ideal for photographing landscapes and architecture, it also allows us to capture a different perspective in sports documentaries. With a constant f/4 aperture, it delivers fine image quality regardless of the selected focal length while maintaining a compact design. Optical resolution is extremely high in the middle and very good in the corners. Distortion is almost completely eliminated, vignetting is low, and chromatic aberration doesn’t exist at all. State-of-the-art optical coatings minimise the effects of flare. The lens is also equipped with the latest stabilisation technology including peripheral control, which allows us to capture blur-free images in difficult lighting conditions without a tripod. Overall, it’s an amazing lens, but at a price.
