DxOMark has just tested the new AF-S NIKKOR 24mm f/1.8G ED lens (Amazon/B&H/Adorama), this lens is the seventh f/1.8 prime G-type lens to be added recently to the Nikkor lineup. From the test result, we can see this lens is even better than some f/1.4 lens in 24mm range. See the test result below:
Nikon 24mm f/1.8G vs Sigma 24mm f/1.4 vs Samyang 24mm f/1.4
Nikon 24mm f/1.8G vs Nikon 24mm f/1.4 vs Nikon 14-24mm f/2.8G
Conclusions from DxOMark:
For Nikon shooters after a top-end wide-angle lens for high-quality architecture, landscape, and interior shots, or just to fit a bit more in the frame, there’s everything to like about the new Nikon 24mm f/1.8G. Affordable and outstanding optically, it’s in the top ten for all lenses tested on the D810, as well as being the sharpest 24mm wide-angle tested to date on this camera. Not only that, it boasts better chromatic aberration results and similar other lens metric scores when compared to the 24mm f/1.4 competition from Sigma and Samyang. If you need the f/1.4 maximum aperture for low-light work, the Sigma 24mm f/1.4 is a better value than Nikon’s own-brand 24mm f/1.4G option, but both are surpassed optically by the brilliant Nikon 24mm f/1.8G.
