Sigma 50-200mm f/4-5.6 DC OS HSM review

Small but feature-packed, this Sigma zoom lens aims to go large on value for money

Our Verdict

For

  • Small but not too lightweight
  • HSM autofocus and optical stabiliser
  • Includes a focus distance scale, often omitted on budget lenses

Against

  • Lack of outright sharpness at 200mm focal length
  • Stabilisation only consistently gave a 3-stop advantage in our tests
  • Not compatible with full-frame cameras

The Sigma 50-200mm f/4-5.6 DC OS HSM is a very compact telephoto zoom lens with some nice features, including optical stabilisation, reasonably rapid and quiet HSM autofocus, and internal focusing. Even so, the stabiliser only consistently gave a 3-stop benefit in our tests, and handling can be a little awkward, since it's easy to foul the rotating focus ring during autofocus.

We liked

There's an impressive range of features packed into a very compact package.

We disliked

The 50-200mm zoom range is relatively modest and sharpness isn't particularly good at the telephoto end.

Final verdict

Overall, the Sigma 50-200mm f/4-5.6 DC OS HSM is a decent buy at the price.
