EF300mm f/4L IS USM

In addition to the unrivalled optical performance, this 300mm lens is characterized by outstanding mobility thanks to the image stabilizing mechanism. In IS mode, the photographer has two options: mode 1, which is good for still shots, and mode 2, for many shots of moving objects. The optics includes two UD glass elements to thoroughly eliminate secondary spectrum. With a closest focusing distance of 1.5m/4.9ft, you can get in as close to the subject as possible in that unique way only possible with a macro lens. The image stabilizer also functions when using the Extender EF1.4xII and Extender EF2xII to provide that elusive 600mm shooting capability.
