Sigma 18-300mm f/3.5-6.3 DC Macro OS HS M | C £370/$500
What’s good: Big zoom range, good image quality, impressive build quality. What’s bad: Focus ring rotates during autofocus, a bit on the heavy side. Our verdict: Outperforms the Tamron 16-300mm in some respects.
Nikon AF-S DX 18-200mm f/3.55.6G ED VR II £650/$650
What’s good: High-spec autofocus and VR, good overall performance. What’s bad: Limited zoom range next to more recently launched superzooms. Our verdict: It’s a nice lens, but offers relatively poor value compared with Sigma and Tamron competitors.
