This has been my favorite thread this year and will no doubt put one of the many mentioned lenses into my stash. Must say I'm surprised at the one making the final cut. Maybe I'll try another.
I had the 24-85 VR on my D90 some years ago. It was OK, but I would never use it on a FF. Maybe I had a bad one but was glad to trade it. It was not as good as the one in this review:

Back when I had a
D7100 I found that it had two different settings related to aperture control for lenses with an aperture ring. Four combinations that gave me fits trying to get the manual lens to work (meter and report aperture accurately) and then to restore proper camera light meter operation for more modern lenses.
The D750 and others with just one menu item makes more sense. And no matter which setting you choose, it overrides it for the old / manual aperture lenses when they are mounted.
Stating the obvious and repeating others comments above: The menu item is to give you an option with computer chip lenses that have an aperture ring (like a 50 1.8D).
I went through similar analysis, not as deep, and happily wound up with a D750 bought used (with a brand new shutter).
It has a low pass filter, but it is a weak one.
Great pictures, even with my DX lenses in DX mode.
I recently read an old article that explained auto-iso with flash.
The explanation was based on extensive testing since Nikon's documentation does not help much.
Unfortunately it depends on which generation of Nikon bodies is in question. The 'get the exposure right' algorithm has changed at least once.
And neither neither is a simple-to-state rule, depends on the metering mode, iso range and a few other things..
I like the f3.3 lenses, just joking, but my super cheap 28-80mm G 3.3-5.6 is surprisingly good. I like posting pictures made with it on my D100 on the forums full of folks with D810/850's.
My first Nikon, back in 1969 or thereabouts, was the EL.
You pick the Aperture and its meter showed the shutter speed. Had a vertical travel shutter, to travel the 24mm faster than those cameras that had to cover the 36mm.
Eventually moved up to an F2AS heavy beast. But my EL pictures were more numerous and still are my film favorites.
It would take a lot of research for me to move to a D600 or 700 series given all the many recalls for shutter replacement and sensor oil spots on these cameras.
A good one would be a delight for me but I'm spooked by the risk.
I've had the D300S and D90.
Happily sold the D300S and kept the D90.
The memory "banks" concepts and usability on the 300 made me crazy.
Picture quality is identical between the two.
Clearly the D300 is built better and has better weather sealing...
Not enough to change the decision for me.
I've completely disassembled several of these on the bench just to marvel at the design and all the assembly labor and hundreds of small parts. Lots of tiny screws, I mean lots.
