The Nikon 50mm f1.8 S was one of Nikon's first lenses for the Z mount system and it has been designed to cater to the hybrid shooter who wants a single lens that can do anything. Video, landscape, wedding, portrait, or even street photography. While the f1.8 aperture isn't exciting for a lot of people, the versatility makes it a great place to start when building out a new kit. The lens is weather-sealed, has a silent stepping motor focusing system with very little focus breathing. It's very well corrected, incredibly sharp with a very manageable size and weight.
Nikon is slowly winning me over at becoming my favorite full frame camera system. I still like the EOS R, I think it's a more capable camera in terms of versatility, mainly because of the 30MP sensor and the flippy screen that is so nice for landscape work, but I actually enjoy using the Nikon Z6 more. The main thing that's really got me excited about the Nikon system is the (somewhat) affordable high quality f1.8 AF glass, which is what you're seeing with all the samples in this post.
