Nikon D7000 User Manual page 22

By specifying lens data (lens focal length and maximum aperture), the user can gain
access to a variety of CPU lens functions when using a non-CPU lens (_ 270). If the
focal length of the lens is known:
• Power zoom can be used with SB-900, SB-800, SB-700, and SB-600 flash units
(available separately)
• Lens focal length is listed (with an asterisk) in the playback photo info display
If the maximum aperture of the lens is known:
• The aperture value is displayed in the control panel and viewfinder
• Flash level is adjusted for changes in aperture
• Aperture is listed (with an asterisk) in the playback photo info display
Specifying both the focal length and maximum aperture of the lens:
• Enables color matrix metering (note that it may be necessary to use center-
weighted or spot metering to achieve accurate results with some lenses, including
Reflex-NIKKOR lenses)
• Improves the precision of center-weighted and spot metering and i-TTL balanced
fill-flash for digital SLR
The camera can store data for up to nine non-CPU lenses. To enter or edit data for a
