6. Distortion

The distortion performance of the150–600 mm class lenses is interesting as at every focal length they show pincushion deformations. The Sigma C 150-600 mm is not an exception to that rule. In the case of the APS-C sensor the distortion shouldn’t bother you at all as it doesn’t exceed +1.0%. If you want to know precise values then at 150, 300, 450 and 600 mm focal lengths they are as follows: +0.49%, +0.54%, +0.51% and +0.46%.

In the case of the more expensive Sigma S 150–600 mm the distortion level never exceeded +1.0% even on a bigger sensor. The cheaper model didn’t manage to correct it so well – its results are ranging from +1.16% to +1.34%. It is clear the cheaper Sigma, tested here, is closer to the Tamron than its more expensive brother. The comparison of full frame results achieved by all the lenses mentioned above, is presented in a chart below.

	150 mm	300 mm	450 mm	600 mm
Sigma C 150–600 mm f/5.0–6.3 OS	+1.16%	+1.34%	+1.17%	+1.30%
Tamron 150–600 mm f/5.0–6.3 VC	+1.37%	+1.29%	+1.34%	+1.32%
Sigma S 150–600 mm f/5.0–6.3 OS	+0.54%	+0.76%	+0.71%	+0.75%
