Beautiful and Small! Canon RF 70-200mm F4 L IS USM Review

The 70-200mm lens is a workhorse lens, but the optics are also workhorse-sized. The Canon RF 70-200mm f4 IS USM is the company's shortest and lightest to hit the category. Tipping the scales at a pound and a half, the lens promises all of the zoom range with none of the backaches that come with working with a lens like the three-pound EF 70-200mm f2.8L USM.
