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 120-300mm F2.8 zoom lens. 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.
Embodying the concept of our Sports line of lenses, this lens responds directly to photographers' needs with outstanding action-capture performance.
In addition to the highest levels of optical performance and photographic expression, Sigma's new Sports line of lenses offers the kind of action-capture performance that precisely executes the intentions of the photographer. Uncompromising optical performance and photographic expression allow the photographer to shoot fast-moving and distant subjects, while exceptional functionality makes possible excellent shots even in the most challenging of situations. The SIGMA 120-300mm F2.8 DG OS HSM is the first lens to embody the concept of the Sports line. Fully customizable, it allows the photographer to create his or own specification. It is an ideal choice for photographing many different subjects; birds, wild animals, airplanes, motorsports, and even portraits. And Sigma's exclusive software makes the lens extremely easy to customize.
This lens features durability that stands up to challenging photographic situations and hard use demands along with the intuitive and enjoyable usability that photographers need. Since the lens uses Sigma's inner focus and inner zoom technologies, adjusting the focus and zoom rings does not change the length of the lens, resulting in excellent hold for the selected ring positions. Since the front of the lens does not move, the lens is compatible with a circular polarizer. In every way, Sigma has designed the lens for exceptional usability. The zoom ring is textured to allow fingers to find the correct position easily. Designed for seamless integration with the rest of the lens, the four control switches feature carefully placed lettering and buttons and specially shaped screws. The lens hood has also been completely redesigned, even down to the screws that connect it to the lens, and the newly designed tripod collar provides for connection to a camera strap.
HSM (hypersonic motor)
HSM (hypersonic motor) delivers high AF speed and extremely quiet performance. An enhanced algorithm offers even smoother automatic focusing, and full-time manual focus override is another key feature.
TSC (Thermally Stable Composite)
Conventionally it is considered essential to leverage the qualities of metal and polycarbonate in camera and lens layout design. A first for the industry, the barrel of the new series of Sigma lenses features a new TSC (Thermally Stable Composite)* that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens.
*TSC (Thermally Stable Composite) offers thermal expansion characteristics similar to those of aluminum. Parts made with TSC deform less, making possible lens construction of extremely high precision. Compared to polycarbonate containing 20% glass, a commonly used material, TSC offers approximately 70% higher elasticity, and compared to polycarbonate containing 30% glass, it offers 25% higher elasticity. (Comparison is between Sigma-produced components.)
