6. Distortion

The previous stabilized Sigma 70-200 mm f/2.8 didn't stand out in this category when compared to its direct rivals. On the full frame it got results of −1.36%, +0.75% andá+1.59% at, respectively, 70, 135 andá200ámm. It fared weaker than not only the brand name Canon and Nikon devices but also than the Tamron SP 70-200 mm f/2.8 VC.

In the case of the new model we expected a better performance in this category and... unfortunately we were disappointed. An improvement is only visible at 70 mm where distortion decreased to −0.64%. You have to pay for it with a weaker performance in the middle of the focal range (+1.32%) and a slight decrease at 200ámm (+1.62%).

Of course as long as you stick to the smaller APS-C/DX sensor deformations are practically invisible, amounting to −0.36%, +0.47% andá+0.62% at 70, 135 and 200 mm respectively.

Attaching the teleconverter helps noticeably to fight off distortion – its level amounts to +0.28% for the APS-C/DX sensor and to +0.53% for full frame.
