Canon RF 400mm F2.8 L IS USM Lens

Canon RF 400mm f/2.8L

Quite the lens. It focuses quickly, is great in low light and takes a nice image. The lens hood is rather long and is difficult to use in a smaller car when using the car as a mobile blind. Canon does make a shorter lens hood but the price is ridiculous. I am quite pleased with the lens overall. It all performs well with both a 1.4 and a 2X entender.
