Nikon 20mm 1.8s Vs Nikon 20mm 1.8G For Astrophotography

Nikon 20mm 1.8s Vs Nikon 20mm 1.8G For Astrophotography

Ever since the news of the Nikon mirrorless system was announced it was fair to say I was a little excited, then I had seen the changes to the lens mount and knew at an instant that this could finally produce the quality of stars across the frame of an image I was used to seeing from shooting with telescopes optimised for star quality corner to corner.

It had taken a little while for the wide angle lenses to be released but when they did I jumped on them. The Nikon 20mm 1.8s lens is a stunning lens, much larger compared to the older Nikon 20mm 1.8G lens and the new 20mm 1.8s lens feels a lot more solid and better built.

But let's bypass all the basic info about the lenses and get straight to business. When it comes to nightscape photography and analysing my own photos I can be a bit fussy. For me it comes down to three factors.....

  1. Can I shoot with the lens wide open
  2. Does the lens produce chromatic abberation wide open
  3. What are the stars like corner to corner

Usually with lenses of the past I've been shooting around F/2.8 aperture due to the performance of these lenses...... but not anymore!

So lets compare images... 

 As you can see in the above comparison the stars are sharper and more pinpoint across the whole frame, but lets have a closer look at the corners.

Overall I believe the Nikon 20mm 1.8s lens is far superior over the 20mm 1.8g lens and the choice I personally made to switch over to the Nikon Z system for astrophotography was the perfect one to make.
