What Digital Camera
23 January 2009
Summary: This test has proved that the low-cost label so often associated with independent lenses indicates only part of their appeal. Image quality and usability are also strengths and Tamron's 17-50mm f/2.8 also manages to be surprisingly compact.
Summary: Outstanding optical performance is spoiled slightly by some increase in fringing at the wide end, but generally this is a very capable and handy optic, with a decent price, especially for Nikon, Canon and Sony users. Overall, it’s a very good option
