AF-S Nikkor 85mm f1.8G

It's hard to resist current Nikon's rebate, so I bought this little gem to be my second portrait lens (first one being a Sigma 50mm f1.4 DG HSM).  The built quality isn't as bad as I expected, in fact, the ergonomic is great. The size and finish match D600 quite well, and the focus is fast and quiet.
