Get a 35
OR a 28, don't get both. They are close enough in field of view that they both serve the same role -- a wider than normal, but not a very wide. I have chosen to use a 28 for the very important reason that I happen to already have one. As I said, I love my 35 on the Leica and use it pretty much for the same scenes.
G lenses are not DX only, most are FX actually. G lenses I'm taking about are just ones without an aperture ring.
For 35mm, a used version of this guy:

This is the G version:

If I had a choice I'd get the AF-D version because less expensive and smaller.
As for what lenses you can use in general -- the N75 takes all autofocus lenses except for the E series with electronic diaphragms and af-P with stepper motors.
-- You can use AF or AF-D. These are screw-type autofocus, the D means the lens sends distance information to help with things like TTL Flash metering.
-- You can use AF-I or AF-S. These have an internal motor to focus. I stands for Internal, S stands for "Silent Wave" but they're both autofocus lenses that use their own motor
-- You can use G lenses -- these are usually AF-S lenses and don't have aperture rings.
-- As a side note, If you have a lens with VR, it will work on your camera.
-- You want FX format,
never DX. DX is for the smaller digital sensor so it vignettes something fierce in 35mm
-- For pre-autofocus lenses, you can mount and shoot in manual with AI and AI-s lenses but the meter won't work with them. You can add a chip to make them work, which isn't hard. I've done it. But it's a hassle so you might avoid them right now.
Hope that helps if you're searching for bargains in the future.
