Non-CPU Lenses
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. If the
focal length of the lens is known:
• Automatic power zoom can be used with optional SB-800 and SB-600 Speed-
lights
• Lens focal length is listed (with an asterisk) in the playback photo info display
When the maximum aperture of the lens is known:
• The aperture value is displayed in the control panel and viewfi nder
• 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, in-
cluding Refl ex-Nikkor lenses)
• Improves the precision of center-weighted and spot metering and i-TTL Bal-
anced Fill-Flash for Digital SLR
