As part of the sixth generation in Canon's 400-millimeter f/2.8 series, the Canon EF 400-millimeter f/2.8L Image Stabilization III UltraSonic Motor Lens is well worth its expensive price. It has come to be the world's lightest 400-millimeter f/2.8 lens, and it is highly recommended for professionals and advanced photographers. This lens is perfect for photographing nature, sporting events, and more. It is primarily perfect for these types of photography due to its lightweight since it can be used handheld rather than with a monopod or tripod. The weight in the lens has been rebalanced towards the rear of the lens, making it easier to support in comparison to previous versions since its weight is redistributed to the palm of your hand rather than the front of it.

Since the EF 400-millimeter lens is part of the L series, it has excellent and sturdy build quality. The lens is also weather sealed in order to prevent dust and moisture from making its way into it, and the front element has a fluorine coating in order to repel dirt, water, and grease from the surface. The Canon EF 400-millimeter lens has a great focal length and max aperture that allows for sports, wildlife, and photojournalistic opportunities. With this focal length, it is possible to capture subjects without being too close to them, whether it's an athlete out on the field, or an animal out in the wild, they will not need to be disturbed. Any professional or advanced photographer should consider adding the Canon EF 400-millimeter f/2.8L Image Stabilization III UltraSonic Motor Lens to their collection.
