Hier zeggen ze dat de 300mm f/4 + 1.4x teleconverter scherpere foto's maakt dan de 80-400mm.
Many have asked how this lens compares at 300mm to the 300mm f/4 and also at 400mm to
the 300mm f/4 with 1.4x converter. In short, it doesn't. The 300 f/4 is an amazingly sharp lens
and trounces the 80-400 in resolution throughout the frame even when using DX crop mode and
the 1.95x crop (1.3x DX crop). Even with the 1.4x attached to the 300, it handily beats the 80-
400.
Er worden daar meerdere objectieven vergeleken met de 80-400mm, ook de 150-500mm van Sigma:
A comparison of the new 80-400mm versus the 70-200 with 2x or versus other offerings like the
Sigma 120-400, 50-500 and 150-500 also reveals this lens significantly superior to those
options. The Sigma lenses are dispatched easily with this lens being sharper in all regimes and
all parts of the frame. It really isn't close at all. Some have also asked how it compares to the
Canon 100-400. The new Nikon 80-400 is superior to this very old lens in every category
except build strength which easily goes to the all metal Canon lens. But optically and especially
in auto-focus speed there is no comparison. It also easily outperforms the Nikon 70-200 f/2.8G
VR2 with 2x III teleconverter in all regimes. At 280mm, the 70-200 f/2.8G VR2 with the 1.4x II
shot at f/5.6 is slightly superior in the center and significantly superior on the edge for sharpness
and resolution to the 80-400 at f/5.6. At f/8 the centers are equal but the FX corners are still
superior using the 70-200/1.4x combo.
