Alex get the 50 1.8g as your first lens. It is excellent, light, focuses very fast and accurately and is cheap. especially used ....
And looks and balances great on the F6.
The previous model (still made) 50 1.8d is also excellent and even cheaper.
Forget about wanting an aperture ring with the AF lenses. I was like that too until I tried those lenses. The aperture dials on Nikon’s AF lenses (that I tried) are horrible and plasticky feeling with lots of stick. Not smooth, precise and beautiful like on the AIS lenses.
After I used it once I just used the camera body to control the aperture.
