Rivaling a fixed-focal length lens in image quality

Featuring F2.8 brightness and rivaling a fixed-focal length lens in image quality throughout the entire zoom range

A professional 300mm F2.8 telephoto with powerful zoom capability, this lens allows complete customization, so you can tackle tough situations with ease.

Offering excellent image expression and a low F-number, the large-aperture 300mm F2.8 lens is a favorite piece of equipment among professional photographers. With the idea of taking this spec to the next level with powerful zoom capability, SIGMA developed the SIGMA 120-300mm F2.8 zoom lens for Canon. It is difficult to compose shots with traditional 300mm lenses. In the case of sporting events, performances on stage and other situations in which it is difficult to change your position, you often lose the desired shot in the process of changing lenses. A large-aperture 120-300mm F2.8 zoom lens, however, eliminates the need for most lens changes, allowing the photographer to adjust zoom and easily achieve the desired framing. Even in the most difficult of situations, this lens truly empowers photographic expression.
