Sigma 120-300mm F2.8 DG OS HSM

Unique fast long telephoto zoom

The Sigma 120-300mm F2.8 is not a cheap lens by any means, but there's else nothing quite like it on the market. It gives longer range than conventional 70-200mm F2.8 telezooms, and offers a particularly interesting value proposition compared to the camera manufacturer's 300mm F2.8 primes. The lens features an ultrasonic-type focus motor and built-in optical stabilization, and it's also dust- and splash-proofed. It's also compatible with Sigma's USB Dock (click here for our review), which allows detailed AF micro-adjust and tuning of the lenses autofocus and stabilisation systems.

Key specifications

  • 180-450mm equivalent range when used on APS-C cameras
  • 105mm filter thread
  • Optical image stabilisation
  • Ring-type ultrasonic focus motor
  • 1.5m minimum focus distance
  • For APS-C / DX and full frame cameras
  • Canon, Nikon and Sigma mounts

Optically the 120-300mm F2.8 performs extremely well. It's impressively sharp, and chromatic aberration, vignetting and distortion are all kept relatively low. It's not quite as good as a 300mm F2.8 prime, but it's rather less expensive, and not very much larger or heavier. Plus, of course, it zooms.

This is a DG lens, which means it will work on both full frame and APS-C / DX format SLRs; on the latter it offers a 180-450mm equivalent range.  It's available in mounts to fit Canon, Nikon and Sigma SLRs. If you want a fast stabilised telezoom but are put off by the 120-300mm's size and price, Sigma also makes the 70-200mm F2.8 EX DG OS HSM, which earned our Silver Award when we reviewed it in September 2010.
