Nikon 18-55 f/3.5 - 5.6 VR - kit lens. Don't really use this one anymore.
Nikon 55-300 f/4.5-5.6 VR - my go-to zoom lens for far-away shit. Great for zoos, etc.
Nikon 35 f/1,8 - favourite lens
Nikon 50 f/1,8 - nice for portraits
I've got a crop-sensor camera, so effective focal length is x1,5.
Szeph el ratÃ³n: what was wrong with the 50mm? If you sell the 17-50 (effective focal length 29-80mm?), I would guess that the 35mm prime would be your best option.
