Taking Photographs—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 attached Speedlights
• Lens focal length is listed (with an asterisk) in the playback photo info dis-
play
When the maximum aperture of the lens is known:
• The aperture value is displayed in the top 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,
including Refl ex-Nikkor lenses)
• Improves the precision of center-weighted and spot metering, i-TTL Bal-
anced Fill-Flash for Digital SLR, and Multi-Sensor Balanced Fill-Flash for
Digital SLR
