The Canon RF 70-200 F4L IS USM is a standard telephoto zoom for the company's full-frame mirrorless system. The lens is compact given its spec: it's 119mm (4.7") long and weighs in at 695g (1.5lbs).

It features 16 elements, four of which are UD glass, and dual Nano USM focus motors. The lens's built-in image stabilizer reduces shake by up to 5 stops and, when paired with a camera with a stabilized body, that number rises to 7.5 stops. The lens's minimum focus distance is 0.6m (2ft) throughout its zoom range, and its maximum magnification is 0.28x at 200mm.

As with all RF L-series lenses, the RF 70-200mm F4 is sealed against dust and moisture and has a fluorine coating on the front element to repel water.
