There are plenty of 50mm options for Nikon.
Why would you use a fast prime like a 28/1.4 for landscapes? Is it really the best choice in that FL?
The Nikkor e-series lenses are sharper than the older g-series ones. I'd only want a 28mm because it would be "evenly spaced" between a 19-20mm lens and a 50mm lens.
It's stupid that people still want that archaic blurry/jerky 24FPS look from like 80-90 years ago.
If you shot 24p video 2 years ago and wanted to add/edit, more/different, video to that file and could not shoot at 24p that would be problematic.
