Mike99999: I currently use a D7000 with Tokina 50-135 f/2.8. This is a wonderful combination: incredible sharpness and nice bokeh. I understand that this is roughly equivalent to using a 70-200 f/4 lens on FX.
What is lacking in the Tokina lens for me is VR, and I could use more reach. Being an amateur, I'm not willing to pay for, nor carry a 1.5 kg lens. Therefore this new 70-200 f/4 seems like a godsend.
Any opinions on using this type of lens on DX?
My wife has the same combination.Very nice.
