Dude, we get your point.
THIS is not the lens to use to make it is all I'm saying.
Find an E (electronic diaphragm) or a G lens and it isn't backwards compatable. But Nikon only just announced the discontinuation of some D lenses, and the D line goes all the way back to early AF days.
Nikons are great. I love mine to death, but the mirrorless don't drive old lenses without internal focusing so they're a pretty clean break from the old lens technology. Likewise, the E lenses don't work with pre 2006 camera designs, so literally no film camera can use the electronic diaphragm, and the G and later lenses don't have an aperture ring. Plenty of issues that you point to if you're looking to have one lens to go from an early AF camera to a DSLR to a mirrorless with the adapter.
Their menus are also kludgy as all get out. Nikon is bad at software, always was.
But this flailing about feels too much like s fanboy who just wants to pick a fight. Nobody gives a shit about the Canon/Nikon holy wars anymore, except for people who want to fight because they want to fight.
And, frankly, picking on the AF50 as the inferior lens is kind of telling. Shows you don't know Nikon at all, you're just fanboying. It's the ultimate cheap SLR lens. Sharp, fast focus, and cheap as chips. $65 used, $110 new. If you want to prove your superiority, you don't go after the sweet, easy going kid that everyone loves. Go after the prickly one with obvious flaws.
