For sale a Canon EF 100-400mm f/4.5-5.6L IS II USM lens which is a top-quality telephoto zoom lens designed specifically for Canon EF mount cameras. It has been used lately with an RF to EF adapter on a canon R5. Also included is a Canon EF 1.4x II Extender which is in mint condition and increases the focal length to 560mm on a full frame body and 896mm on an APS body. The 100-400mm lens comes in its original box with all parts as supplied by Wex. This lens is in used but excellent condition with no faults or damage as per photos. 

There is dust behind the front element. This does not impact the images taken with this lens, because the dust particles are located a long way away from the cameras sensor (please message if you have any questions about this, but there's lots of infomation online about why dust is not an issue on the front element of telephoto lenses – and why it's a massive issue if you have it on or close to your camera sensor).
