@blessingscaptured, I used the Sigma 17-50mm 2.8 lens for a few weeks before, and couldn’t believe the optical quality and versatility of this lens. I would highly recommend it. The constant aperture makes a big difference.
Sigma 17-50mm 2.8 lens for Nikon F-mount
I got mine for $290 used, but it looks like they are going on B&H for $500+.
