Sigma 18-250mm F3.5-6.3 DC Macro OS HSM
The 18-250mm F3.5-6.3 DC Macro OS HSM is Sigma’s latest super-zoom for APS-C SLRs, distinguished from the previous version by the addition of ‘Macro’ to its name. It’s is one of the best lenses of its type, with decent optics, fast autofocus and effective image stabilization. The 18-250mm is available in mounts for all current SLRs, although the Sony and Pentax versions don’t include image stabilization and drop ‘OS’ from the name. Overall it's a reliable performer, and its close-up capability is handy too.
