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
