Nikon D700 manual Non-CPU Lenses, 210, Focal Length Not Listed, Zoom Lenses

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 SB-900, SB-800, and SB-600 Speedlights (available separately)

•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 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
