As with the primes, a number of zoom models have also seen their sharpness scores improve dramatically with the D7100. At the top of the rankings, the upgraded DX format only Sigma 50-150mm f/2.8 EX DC APO HSM and the current AF-S Nikkor 70-200mm f/2.8G ED VR II full-frame model sit beside the new Tamron SP 70-200mm f/2.8 Di VC USD with a DxOMark score of 23 points. The Tamron had the slightly higher (averaged) sharpness score before we amended the list, adding the updated Sigma 50-150mm to our findings. We’ll look more closely at the individual performance of those lenses at different apertures and focal length settings and reveal how they affect the rankings in part III. If based on sharpness alone, though, the Sigma is the better performing model of the three and claims the top spot in this group of focal lengths. It also happens to be very modestly priced, but bear in mind it’s not a full frame lens and can only be used on APS-C bodies, potentially limiting its usefulness in dual format systems.

It’s no secret that third-party lens makers, Sigma, Tokina and Tamron have established a wide-range of zoom models in Nikon mount and they continue to perform well against their Nikkor branded counterparts. We’ll compare the best performers against the Nikon models to see how they differ in optical quality.
