Sigma 50/1.4A vs Nikon 50/1.4G, 50/1.8G (Nikon D810, Decorated Bike)

Shot on the 36-megapixel Nikon D810.

This multi-lens comparison evaluates the Sigma 50mm f/1.4 DG HSM A in Nikon F mount against Nikon’s two mainstream 50mm lenses: the 50/1.4G and the 50/1.8G. The Nikon offerings are typical of Nikon offerings meaning they are good performers stopped down 2-3 stops and unexciting at wider apertures.

The comparison is similar to the one comparing the Sigma 50/1.4 DG HSM A in Canon EF mount to the Canon 50mm lenses. The Nikon D810 has a higher resolution sensor also of a much more recent design than the Canon 5D Mark III.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.

Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.

  • Make better images by learning how to get the best results right away.
  • Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
  • Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
  • Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
  • Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
  • Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
  • Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
