Hi guys,
I recently bought a Nikon D700 to replace my Nikon D300 and Sigma 10-20, which is a DX lens.
I am now looking to get a similarly wide full frame lens that also takes filters.
I don't really want to go longer than a 10-20 equivalent on DX, therefore nothing longer than the Sigma 15-30 which would be one option at this stage. Are there any other options?
