6. Distortion

In the chart below you can see what distortion results the tested lens had on the Nikon D200 and on the Nikon D3x.

1.89%


As you see, on both sensors at the shortest focal length the distortion is negligible and, within the margin of measurement errors, close to the zero level. At longer focal lengths the deformations keep more or less the same level of 0.8% for the DX sensor and about 2% on full frame. These aren’t bothersome values so it would be hard to complain here. Our chronicle duty makes us only say that the values of the rival Sigma were by a fraction of a percent lower.
