Canon RF 70-200mm F4L IS USM Ideal for travel, sports and wildlife thanks to its compact size and light weight, the RF 70-200mm F4L IS USM has pro features in a small size and won’t take up much room in a kit bag. As well as Air Sphere Coating, four UD lenses correct aberrations while a 9-blade iris and constant F4 aperture give superb bokeh, even at its closest focus of 0.6m. Designed for stable handheld shooting, the Optical Image Stabilizer gives great confidence, with up to 5-stops available.
