Canon has released two new RF-Mount lenses to the ever-growing R-mount lens lineup: RF 24-50mm f/4.5-6.3 IS STM and RF-S 55-210mm f/5-7.1 IS STM. The RF-S lens line, optimized for the smaller APS-C sensor size, expands with the Canon RF-S55-210mm F5-7.1 IS STM lens. This telephoto zoom gives coverage equivalent to an 88–336mm lens on a full-frame camera. The lens opens the door to telephoto photography and videography, with 4.5 stops of optical image stabilization and close-focusing that can fill the frame with a subject roughly 2×3 inches in size (at its 210mm zoom setting and minimum focus distance). And it does all this in an incredibly lightweight and compact package.

The 55-210mm f/5-7.1 IS STM is constructed of 11 elements arranged into eight groups, which include two UD lenses, and features a seven-bladed aperture diaphragm. A screw-type STM motor drives the focus, with a minimum focusing distance of 0.7 meters (2.4 feet) at 210mm and one meter (3.3 feet) at 55mm. The onboard optical stabilization provides 4.5 stops of shake reduction, and the front filter size is 55mm.

The Canon RF24-50mm F4.5-6.3 IS STM is a new, compact standard zoom lens for full-frame EOS R-series cameras. Ranging from true wide-angle to traditional standard lens coverage at 50mm, the lens is a travel-friendly design with an extremely compact exterior. The RF24-50mm F4.5-6.3 IS STM lens is just over 2 inches long when fully retracted and under 3.5 inches when extended — weighing less than half a pound. Optical Image Stabilization, with 4.5 stops of shake correction, further enhances its appeal for video and still-image shooting. It’s also useable on an APS-C sensor Canon camera, where the lens’ effective coverage is equivalent to what a 38–80mm would deliver on a full-frame camera.
