I have several Leica cameras and a good number of their lenses, but I still have most of my old Nikon glass. I regret selling my Nikkor AIS 85 mm f/1.4.
Great comparison, very helpful!!! I actually went for the Nikon 58mm after watching your videos. Sharp in the middle, beautiful falloff. I own a bunch of different platforms in both film and digital. When shooting digital, so far my favorite lenses for portraiture have been the 55mm 1.4 Zeiss Otus shot on the Nikon Z9 and 50mm 1.4 Summilux M (2023) shot on the Leica M11M. Lets see what the 58mm looks like adapted to the Leica.
