Currently I have a wide angle (Tokina 11-16mm F2.8), a tele (Nikkor 70-300mm VR), and a portrait (Nikkor 50mm F1.4G, so 75mm on DX format to be a portrait lens).
I used to have a Sigma 18-50 F2.8 HSM, but was sold out several months ago mainly because I was suffering a fever of upgrading to FX system so I wanted to get rid of all DX lenses.
Now I’ve been calmed down by my “boss” to stick to my current D80 gear, and I start to reconsider my lenses.
After the trip to Prague during the Easter, I figured out that only Tokina 11-16 and the Nikkor 50 F1.4G can not cover the most useful focus lengths during the travel.
It seems the one below is what I am looking for:
AF-S DX NIKKOR 16-85mm F3.5-5.6G ED VR
Compare to my previous Sigma 18-50 F2.8 HSM, this one is wider (16mm vs. 18mm) and longer (85mm vs. 50mm). Well, the constant F2.8 is gone, but even with my previous Sigma 18-50 I didn’t use the max. aperture that much because of the softness (normally I used F4). And I understand that VR II can help to improve the sharpness more than the big aperture.
This investment would be much wiser than moving to a FX body. The latter would demand much more than just a D700 since I would need a standard zoom lens (e.g. 24-70 F2.8) for the FX body as well.
