I recently compared two of my long lenses and am confused by the results.
Using my D 300 body I put on my Nikon 80 to 400 lens set at 300 mm.
I then attached my Nikon 18 to 300 mm also set at 300 mm (also on the D 300).
It definitely appeared to me that the 80 to 400 lens had a much narrower (re longer) view than the 18 to 300 mm lens.
I was under the impression that both lenses would have the field of view at the same focal length because of of the same crop factor.

Would appreciate any comments on this situation.
