Tamron's feature-rich new 70-300mm telephoto lens aims to go top of the class

Light in weight and price for a full-frame telephoto zoom lens, but can the Tamron still pack a punch?

Budget macro lens option available in four mounts

Super-Performance, based on three Extra-Refractive elements, a Low-Dispersion element and two Aspherical elements feature in this zoom's construction

Although the Tamron 11-18mm might not look quite as wide as the rival Sigma 10-20mm on paper (a millimetre can make a lot of difference at these focal lengths), the field of view was almost identical in our tests, using both on a Canon EOS 400D

Similar in size and weight to its Sigma rival, the constant f/2.8 Tamron features a layout of zoom ring at the body end and focus ring by the front element. It's available in Canon, Nikon and Sony/Minolta fit
