An Astrophotography Review of the Sigma 40mm f/1.4 DG HSM Art Lens

It takes more than a wide aperture and the right focal length to make a good astrophotography lens. Sigma's 40mm f/1.4 DG HSM Art lens offers a slightly longer but still reasonable focal length paired with that wide aperture, making it a potentially useful candidate for astro work. This great video review takes a look at the lens from an astrophotographer's perspective and the sort of image quality and performance you can expect from it. 

Coming to you from Apalapse, this excellent video review takes a look at the Sigma 40mm f/1.4 DG HSM Art lens. Along with its unique focal length, the 40mm f/1.4 Art comes with a variety of features, including: 

  • Three F Low Dispersion and three Special Low Dispersion elements for reduced chromatic aberrations and improved clarity

  • Super Multi-Layer Coating for reduced flares and ghosting and increased contrast
  • Rounded nine-blade diaphragm for smoother bokeh
  • Hyper Sonic Motor for quick and quiet autofocus
