Travel with a single zoom for space-saving flexibility. A versatile 28-70mm range is useful for many subjects, from big-sky landscapes to portraits, fine art and street photography.
Work quickly and quietly in a variety of situations. The RF 28-70mm f/2L USM features an f/2 maximum aperture, letting you control shallow depth of field in portraits and capture ambience in low light.
The zoom and focal length recomposes and reframes quickly to capture that decisive moment. Focus and shoot in low light, and let Canon’s L-series quality inspire confidence – even in bad weather.
