I wish to upgrade my Nikon D80 but am undecided whether to upgrade to the Nikon D7000 or get a Nikon D90 and maybe another lens.
I have read about some issues with 3rd party lenses.
I predominately do landscape and wildlife photography.
I own nikon dx 18-135 f3.5-5.6G
nikon af nikkor 50mm f1.8D
nikon af-s nikkor 70-300 mm f4.5-5.6
Sigma 10-20mm F4 -5.6
