Buy a Nikkor 17-55 f/2.8 after already owning 35/50/85 primes and 18-105 zoom?

This is my personal opinion based on my previous experience on 17-55/2.8 Nikkor.

If you don't have those 35/1.8, 50/1.4 and 85/1.8, this 17-55/2.8 would make you very happy for the shallow DOF, with wide zoom range.

HOWEVER...

1) You've those f/1.8 and f/1.4 lens already, they will give you much nicer and shallower DOF. So for DOF, the picture from 17-55/2.8 @ f/2.8, won't surprise.

2) For the zoom range, your 18-105VR provide wider zoom than the 17-55 already. So 17-55 won't surprise you on the zoom range neither.

SO... Something out of the box...

Have u considered buying another body? Like the D3200? Such that you've your 85/1.8 and 18-105 in two bodies ready for shooting.

IMHO, the ideal combo for your need/requirement would be a FX body with 24-70/2.8. This will provide you a reasonable zoom range and narrow DOF.

But don't get me wrong. Before going to FX, I loved my 17-55/2.8! It's super sharp. I'm still regret to trade it for the 24-70. Too bad that I couldn't keep both.

Hope this helps.
