Using Non-CPU Lenses (Non-CPU Lens Data)

Non-CPU lenses ( Non-CPU lenses and Other Accessories ) can be used in exposure modes A and M. Aperture is set using the lens aperture ring. Entering lens data using the [Non-CPU lens data] item in the setup menu grants access to the following CPU lens functions.

  • Entering the focal length:

    • allows use of power zoom with optional flash units and

    • allows lens focal length to be listed, with an asterisk (“*”), in the playback photo info display.

  • Entering the maximum aperture:

    • allows the aperture value to be displayed in the top control panel and viewfinder,

    • allows flash level to be adjusted for changes in aperture in auto aperture (qA) mode, and

    • allows aperture to be listed, with an asterisk (“*”), in the playback photo info display.

  • Entering both the focal length and the maximum aperture allows use of:

    • color matrix metering (Note that color matrix metering may not produce the desired results with some lenses, including Reflex-NIKKOR lenses. In these cases [Center-weighted metering] or [Spot metering] can be used instead.)

  • Entering both the focal length and the maximum aperture improves the precision of:

    • [Center-weighted metering],

    • [Spot metering], and

    • i-TTL flash control

Teleconverters and Zoom Lenses

  • If the correct focal length is not available, for example because you are using a teleconverter or zoom lens, choose the next largest value.

  • The maximum aperture for teleconverters is the combined maximum aperture of the teleconverter and the lens.
