How to tell a Nikon or other-brand DX lens from an FX lens?

Question

I'm thinking about getting the Nikon D7000 body-only, and want to know how to tell an FX lens from a DX lens. I may upgrade in the future to an FX body and would like to have glass ready to go when I do.

I was looking on the B&H site and can't tell what lenses are FX and what's DX. Any help on this?

Answer

For Nikon, it will list with "DX" in the name, otherwise its a FX lens. For example, on the B&H page, it lists the 35mm DX as "AF-S Nikkor 35mm f/1.8G DX Lens".

For Sigma lenses that work with Nikon, its the "DC" that indicates a DX sized lenses.

For Tamron lenses that work with Nikon, its the "Di II" that indcates a DX sized lenses.

If it doesn't have one of those, its a normal, "FX" sized lenses.

(And realize that FX lenses will work with the D7000, as well as the DX lenses) .
