Guys, you know Rome wasn't built overnight. Nikon's timing (and Canon's also) to migrate to mirrorless is unfortunate due to Covid. A lot of things are slowed down and the market is seriously affected. One of mirrorless's main advantage is wide-angle lenses. It makes perfect sense to build up that advantage first and let people adapt F-mount teles during the transition. In two years we already have 14-24mm/f2.8, 14-30mm/f4, plus 20mm, 24mm, 35mm, 50mm and 85mm f1.8 lenses. It is not a great situation for Nikon, but so far they manage ok under difficult circumstances. Canon is doing pretty well to with some very fine R5 and R6 bodies. If anything, Nikon is lacking behind in terms of Z bodies. And nothing is really wrong with the F mount. I have perhaps 40 F-mount lenses and they continue to work, although I seriously doubt that I'll buy another F-mount lens, ever.
