The Canon EF 400mm f/2.8 L IS USM lens is a high-quality telephoto lens designed for Canon EF mount cameras. With a maximum aperture of f/2.8, this lens is ideal for capturing sharp and detailed images with excellent low-light performance. It offers both auto and manual focus options, giving photographers flexibility in their shooting styles. Made in Japan, this lens ensures top-notch quality and performance, making it a valuable addition to any Canon photographer's kit. In excellent condition as shown, there is roughly a 3/4mm very very light scratch on the glass but it’s that light my camera won’t pick it up but thought I’d mention.
