Sigma 120-300mm f/2.8 DG OS HSM Sports Lens for Canon EF

The Sigma 120-300mm f/2.8 DG OS HSM Sports is a full-frame telephoto zoom lens built for Canon’s EF mount DSLR system and part of Sigma’s Sports series, representing Sigma’s higher tier of optical and mechanical standards for demanding professional use. Covering a focal range from 120mm to 300mm with a constant f/2.8 maximum aperture throughout, it addresses professional telephoto applications including sports, wildlife, and press photography where a fast, consistent aperture across a telephoto zoom range is a priority. Optical stabilization is built into the lens for effective compensation during handheld shooting at longer focal lengths, and the HSM ultrasonic motor delivers fast, quiet, and responsive autofocus performance suited to tracking fast-moving subjects. The robust construction includes dust and splash resistant sealing throughout the barrel for reliable use in demanding environmental conditions. Compatible with Sigma’s teleconverter system to extend reach when needed.
