Sigma 50mm F1.4 DG HSM A Canon lens performance

IQE

With a DxOMark Lens score of 35 points, the new Sigma A model is an impressive performer. It has very high peak sharpness (close to the maximum on the Canon EOS 5D Mk III), negligible distortion, slightly lower than expected vignetting at maximum aperture and good control of troublesome chromatic aberration. Some fringing is noticeable in the extreme corners of the frame, but chromatic aberration is very low across the field.
