Sigma 17-40mm F1.8 DC ART – The Prime Killer vs. Sigma 16/23/30/56mmF1.4

Arthur has compared the brand new Sigma 17-40mmF1.8 DC ART vs the Sigma APS-C prime lenses quartet, namely the Sigma 16mmF1.4, Sigma 23mmF1.4, Sigma 30mmF1.4 and Sigma 56mmF1.4.

In his video, which you can see below, he says:

  • the Sigma 17-40mmF1.8 will share up and revilalize the APS-C landscape
  • larger than any of these Sigma APS-C primes
  • can the new Sigma zoom replace these prime lenses?
  • the primes let in 2/3 more stops of light
  • on the zoom you don’t have to change lenses
  • less color fringing on 17-40 over the 16
  • the 17-40 is sharper than the 16mm
  • 17-40 optically amazing on the wide end
  • more chromatic aberration on the 16mm prime
  • the 17-40mm has similar sharpness than the Sigma 23mm at f/1.8
  • bokeh balls have similar size on 23mm at f/1.4 and 17-40 at f/1.8. But 17-40 has less green outlining on the bokeh balls
  • 30mm has slight sharpness advantage over the 17-40
  • bokeh is smoother on the 30mm
  • less fringing on the zoom
  • 56 is tougher to compare since 17-40 goes only to 40mm
  • 56mm is sharper
  • after testing, he says he’d consider selling his 16,23 and 30 for the 17-40
