What is your preferred focal length? If it is 10-20 on a crop then maybe the 16-35 F4 would be a good overall bet if you prefer zooms, followed by the 18-35.
If you like primes then I have heard good things about the Nikon 20 1.8 (though it would be a little wide for my tastes).
The 28 1.8 is also very, very good.
Alternatively in terms of third party there is the Sigma Art 20 or 24 1.4's which i expect should be excellent. For longer zooms the Sigma 24-35 f2 also sounds good. I have no experience of them personally but the 35 and 50 art lenses are stellar.
