Camera lenses reviews
The Sigma 120-300mm f/2.8 EX DG OS HSM is a cheaper option than Nikon and Canon's astronomically expensive (although superb) pro telephoto lenses. With the new model you get optical stabilisation (OS), and the whole thing adds up to a lens that is far from a lightweight.
A far cheaper option than a dedicated telephoto lens, can this teleconverter produce results worthy of the Canon or Nikon it's attached to?
One thing that sets fisheye lenses apart from regular ultra-wide lenses is their curvilinear rather than rectilinear optics. But what is it that makes the new Canon EF 8-15mm f/4L Fisheye USM so special?
Light in weight and price for a full-frame telephoto zoom lens, but can the Tamron still pack a punch?
