Lenses

Autofocus is supported only with AF-S and AF-I CPU lenses, which are equipped with an

autofocus motor. IX Nikkor CPU lenses can not be used; other CPU lenses (including AF

lenses not equipped with an autofocus motor) can be used in manual focus mode. CPU

lenses can be identified by the presence of CPU contacts ( 45), AF-S and AF-I lenses by

“AF-S” or “AF-I” at the beginning of the lens name.

The following CPU lenses can be used with the D40.

Type G and D Lenses
Type G and D AF-S and AF-I CPU lenses ( 45) are recommended for use with the D40. Type G and D
lenses support 3D color matrix metering II ( 45). Vibration reduction is available with Type G and D
VR lenses only.
Non-CPU Lenses
The non-CPU lenses listed below may be used, but only when the camera is in mode M. Selecting
another mode disables the shutter release. Aperture must be adjusted manually via the lens aperture
ring; the camera autofocus system, metering, electronic analog exposure display, and TTL flash control
can not be used. Except where otherwise noted, the electronic range finder can be used with lenses
that have a maximum aperture of f/5.6 or faster.
