In my review of the Nikon 20/1.8G in DAP.
Nikon 20/1.8G Aperture Series: Sparkling Lake (D810)
This series is superb in showing the point spread function of the Nikon 20mm f/1.8G. The crops show in a compelling way why aperture f/4 is the peak aperture.
Includes the f/1.8 - f/16 aperture range in HD and UltraHD sizes in color and black and white, as well as large crops across that full range.
The 20/1.8G is Nikon’s best wide angle. At about $797, it’s a steal for what it delivers.
