The winner is... Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM C<br />
The Sigma 18-300mm delivers epic zoom range and best all-round performance<br />
A<br />
remarkable superzoom, the Sigma<br />
18-300mm delivers an enormous zoom<br />
range with surprisingly little<br />
compromise in image quality. It’s impressively<br />
sharp, only really dropping off at the very<br />
longest zoom setting, while keeping distortions<br />
and colour fringing down to relatively low levels.<br />
The Tamron 16-300mm also has a lot going<br />
for it, with superior handling and the bonus of<br />
weather-seals that enable a splash-proof<br />
construction. It’s also the only lens to feature a<br />
focus distance scale under a viewing panel.<br />
For compactness and value for money, the<br />
Sigma and Tamron 18-200mm lenses are both<br />
good buys. The Sigma is slightly smaller,<br />
whereas the Tamron is a little lighter in weight,<br />
and there’s no beating the Tamron for value.<br />
If you’d rather stick to a Canon lens, the latest<br />
18-135mm IS USM is the best performer, while<br />
the 18-200mm is the least impressive.<br />
