What reviewers say

Reviewers praise the useful range, fast autofocus and solid construction, but find substantial wide-angle distortion and vignetting. The Digital Picture is enthusiastic about sharpness and value; Photozone finds weaker telephoto borders in its imperfectly centred sample and considers it overpriced. The Digital Picture achieves the claimed four-stop stabilisation; Photozone advises a margin for inconsistent results in the field.
