Added to my review of the Nikon 105mm f/1.4E Aperture Series in Advanced DSLR:
Nikon 105mm f/1.4E Aperture Series: Sidelit Giant Boulder (Nikon D850)
Includes images up to full resolution from f/1.4 through f/11.
The about $1399 Sigma 135/1.8 DG HSM Art is an outrageously good bargain and an outstanding match for the new Nikon D850.
