THE
AUTOFOCUS
All
I can say is that the autofocus is lightning fast. The "IF" in
the lens denomination has nothing conditional in it, it means
certain, precise and ultra fast "Internal Focusing". After using
consumer lenses on a F4s for close to 10 years the speed is almost
incredible. Whether one who is not a photojournalist really needs
it at this focal length range is another issue, with which I will
not spoil the fun.

The
AF-S 17-35mm f/2.8D ED IF lens mounted on a Nikon F5
|
It
has 10 elements in 13 groups, however 2 of the elements are ED,
and 3 are aspherical. That accounts for increased sharpness,
no chromatic distortion and other aberrations common to ultra
wide angles. Obviously an excellent design.
The
pictures below were taken with an F5 mounted on a tripod, all
shot at f/8 in sequence, on Kodak Supra 400, focused on the green
building, not at hyperfocal distances.
