Nikon 35mm AF S 1.8G DX on FX camera
Probably the best Nikon lens in this price . It is designed for DX cameras (Nikon D7000, D5300, etc.) but work very well with FX cameras. Here are a few samples of this lens with Nikon FX camera. You can expect small vignetting but it’s not big issue and sometimes it gives some artistic look.
