I wanted to get a quick sense of the new Sigma 50/1.4 DG HSM Art, as my mountains trip is coming very soon. Thus a controlled scene shortly after the UPS truck delivered it.
The new Sigma 50mm f/1.4 DG HSM A is a breakthrough in image quality. But many lenses often show their limits at closer range, so how does it hold up against the Canon EF 50mm f/1.2L and Canon EF 50mm f/1.4? In DAP:
Includes HD and UltraHD/4K entire-frame images, as well as an UltraHD/4K central crop series (particularly nice for those with a 4K display). Also various other large crops, all across the full aperture series from wide open to f/16.
This comparison is illuminating, capturing many useful points in one fell swoop. It should be interesting not only as a comparison, but also of practical use in understanding just what to expect from the Sigma 50/1.4 DG HSM A.
There can be no doubt that the Sigma 50mm f/1.4 DG HSM A is the finest 'normal' autofocus lens on the market today. Existing Canon or Nikon normal lenses in the 40mm to 60mm range simply cannot compete with the Sigma 50/1.4 DG HSM A. The Zeiss Otus 55/1.4 APO-Distagon merits distinction beyond the Sigma in several ways, but the Otus is manual focus, so case closed for shooters who need autofocus.
