APS-C f/4-6.3 to f/22-36 Fully compatible with any other RF-mount body. The small form factor and 5.9' minimum focus distance make it useful for intimate portraits in tight spaces. Additionally, the lead screw-type STM AF system is fast enough to keep up with speedy continuous focus while being smooth and quiet enough to work for video. A versatile, video-ready zoom in a compact package, the Canon RF-S 14-30mm f/4.5-6.3 IS STM PZ Lens is made specifically for use as a kit lens for the APS-C-format R50 V mirrorless camera, where it delivers a wide-angle to short telephoto equivalent zoom range of 22-48mm.
