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.
