The Canon RF 24-105mm f/2.8 L IS USM Z is here. It is quite possibly one of the most impressive lenses ever seen, being the first full frame lens to ever offer an f/2.8 constant aperture in tandem with a 24-105mm focal length range. Can it offer the sort of performance and image quality needed to back up those impressive specs? This great video takes a first look at what you can expect.
