Andy Westlake takes a detailed look at a budget all-in-one superzoom for APS-C DSLRs
Tamron 18-200mm f/3.5-6.3 Di II VC – Autofocus
Tamron has included a newly designed DC motor-based autofocus system in this 18-200mm lens, which is very quiet and generally accurate. It isn’t the quickest lens in the world when it comes to focusing, but it’s not exactly slow either. For everyday shooting with static subjects it’s fine, and I rarely found myself waiting for the lens to focus. But in more demanding situations – with moving subjects, or in low light – it can start to struggle. Then again, so would any other £170 lens.
