Nikon 20mm f/1.8G ED vs Nikon 24mm f/1.8G ED
Let’s see how the 20mm f/1.8G ED performs when compared to the Nikon 24mm f/1.8G:
Both lenses perform similarly in the center at their widest aperture, but the 24mm f/1.8G shows better mid-frame performance. Both lenses are excellent when stopped down, with the 24mm f/1.8G yielding better mid-frame and corner performance in comparison. Lenses get very similar in their overall performance at f/5.6.

Now let’s take a look at how the 20mm f/1.8G ED compares to the longer 28mm f/1.8G:
The Nikon 20mm f/1.8G outperforms the 28mm f/1.8G in center sharpness at large apertures until f/2.8. However, once stopped down to f/4 and smaller, the 28mm f/1.8G shows impressive sharpness both in the center of the frame and in the extreme corners.
One word of caution though – as I noted in my Nikon 28mm f/1.8G review, the 28mm lens suffers from both focus shift and field curvature issues.
Overall, the 20mm f/1.8G ED shows excellent performance and Nikon definitely deserves high praise for developing such a great lens optically.
