Well. I want to be able to take photos in local indoor concerts without using the flash and the kit lens isn't going to have the best quality doing that...
This is probably
the most difficult thing to buy a lens for. You need a fast f-stop cos there's usually poor lighting, and a longish lens to isolate people. This combination costs $$$ and can't be "helped" with image stabilization/vibration reduction as you're shooting moving objects. Something like a 200mm f/2 would be acceptably good, but don't even think of looking at prices of lenses in that category.
You're going to have to be creative to pull this off. Some way to get up close and use a lens between 35-100mm (prime, not zoom, I'm just giving the range that tends to have more realistic prices).
Personally - and FWIW I love 50mm on full frame which is about 30mm on your camera - I'd buy a fast (i.e. low f-stop) prime lens between 28-35mm and use that a lot.
OR you might manage your concert shots with something around 100mm f/2ish - I don't know if Nikon make a lens with that sort of specification.
All the best,
Jonathan.
