Lenses behave differently when used with the Nikon N90s. The
imager in the camera provides a smaller image area than 35 mm film.
DCS 410 and DCS 420 (all models) — The imager produces a field of
view equal to using a lens with 2.6 times the focal length of the
lens in use as indicated in the representative lenses listed in the
following figure. For example, an 18 mm lens performs approxi-
mately like a 50 mm lens.
A standard AF Nikkor lens . . . performs approximately like this lens.
