Old AI-S lens

[Rickbb]

Just started using my old AI-S primes on my new D850, the info in the viewfinder shows the F-stop to be 3.3, my 50mm is F1.4. Is it me or am i missing a setting somewhere?

It does this on my 24/2.8 as well.

OK, time to be embarrassed.

Figured it out, have to set up the non cpu lens In the menu. It only lets me store 2 though but that will work, not that hard to change one when I use the other prime.

There's an alternative if you are willing to modify the lens. I install chips on my MF Nikon glass so I can use them on my F5 and digitals. These are my 25-50 f4 and 50-135 f3.5 Ais lenses. Allows use of all modes and EXIF for most.

Here's a link to a how to. I pick up the chips on ebay. Some lenses are easy others not so much.
