The 300mm f/2.8L IS USM telephoto is very fast for a 300mm focal length, it has image stabilization—which makes it effectively even faster, optical quality is unmatched, and it is rugged and made to last. Additionally, Canon claims that this lens has the world’s fastest autofocus for a telephoto.Many users agree as it is one of the lens’ most popular attributes. Telephoto lenses are all plagued by two problems that Canon went to great lengths to address with the 300mm f/2.8L IS USM telephoto lens.
First is the issue of weight, which Canon attacked through the incorporation of a lightweight magnesium alloy in the lens barrel and body. Second, telephoto lenses are known for chromatic aberration—an image color distortion characteristic that occurs to an extent in most lenses and is most certainly not welcome by professionals and those seeking the highest quality images.
Canon reworked the traditional optical layout of telephoto lenses to fix this problem and as a result chromatic aberration is limited and for the most part unnoticeable to the naked eye. Users will find this lens ideal for wildlife, nature photography and action shooting.
