I may also be interested in the Sigma 120-300mm F/2.8.

Also, I have the following lenses which I may part with, so if anyone was interested in a trade/part-exchange, let me know:

Nikon 12-24mm F4G ED-IF AF-S DX
Nikon 10.5mm F2.8G ED-IF DX Fisheye
Nikon 35-70mm F2.8D AF
Sigma 50-500mm f/4-6.3 APO EX HSM (Nikon Fit)
Nikon 24-120mm f3.5-5.6G AF ED-IF VR

Thanks
Richard
