Nikon D600

D300 user here. Although I already own a pretty sizable stable of DX lenses (Tokina 11-16, Nikon 18-200, Nikon 17-55, Nikon 55-200) I would love to go FF and sell my DX glass. Outside of the 17-55 2.8 (which is a fantastic lens) the DX lens options just don't seem to fit my needs as a semi-pro shooter. I would love the smaller form factor DX could provide, but if nikon is unable or unwilling to provide top quality DX glass then FF seems the better option.
