First post here, hello everyone.
It's been a tough decision regarding my 17-55 after going FX (D3s)
I still own my DX (D300s) as a back up and now my 17-55 became redundant.
Unless I use both cameras separately on the same occasion, I almost sure I won't need the 17-55.
It makes more sense to get a 16-35... but it's just heart breaking to lose f/2.8 and focal length.
