Hi there HD.
The camera is a Nikon D300, but the lens is what gives the results.
I used my Nikon 80-200mm f2.8 AFS zoom , NON digital lens.
When on my D300 it gives me equall to 120-300mm.
From my experience its superior to the follow up 70-200 f2.8 VR1 AFS zoom.
I had one, but went back to the 80-200mm zoom, which I found optically better!!!!
OPF
