Non-Cpu Lenses - Nikon D800E User Manual

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:
• Power zoom can be used with optional flash units (0 382)
• 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

Focal Length Not Listed
If the correct focal length is not listed, choose the closest value greater
than the actual focal length of the lens.

Teleconverters and Zoom Lenses
The maximum aperture for teleconverters is the combined maximum
aperture of the teleconverter and the lens. Note that lens data are not
adjusted when non-CPU lenses are zoomed in or out. The data for
different focal lengths can be entered as separate lens numbers, or the
data for the lens can be edited to reflect the new values for lens focal
length and maximum aperture each time zoom is adjusted.
