Non-CPU Lens
By specifying lens data (lens focal length and maximum aperture),
you can gain access to a variety of CPU lens functions when using a
non-CPU lens.
Available functions
• If the focal length of the lens is known:
Automatic power zoom can be used with attached Speedlight
• When the maximum aperture of the lens is known:
The aperture value is displayed in the top LCD panel and viewfinder .
Auto Aperture flash can be used with attached Speedlights (x 155).
• Specifying both the focal length and maximum aperture of the lens:
Enables Color Matrix Metering (x 62).
Functions for improved accuracy
• Specifying both the focal length and maximum aperture of the lens improves
accuracy in: Center-Weighted and Spot Metering (x 63), i-TTL Balanced Fill-Flash*
(x 150), Multi-Sensor Balanced Fill-Flash* (x 154).
* Set the metering system other than Spot.
Available focal length and aperture
• Focal lengths:
6, 8, 13, 15, 16, 18, 20, 24, 25, 28, 35, 43, 45, 50, 55, 58, 70, 80, 85, 86, 100,
105, 135, 180, 200, 300, 360, 400, 500, 600, 800, 1000, 1200, 1400, 1600,
2000, 2400, 2800, 3200, and 4000mm
• Apertures:
f/1.2, 1.4, 1.8, 2, 2.5, 2.8, 3.3, 3.5, 4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9.5, 11, 13,15, 16,
19, 22
Available non-CPU lens
• Non-CPU lens data can be specified with AI Nikkor lenses. Non-AI lens does not
function accurately even when the lens data are specified. To use non-AI lens, select
a lens number in which no focus length and maximum aperture are specified.
Available focal lengths and apertures
• If the corresponding focal length is not listed, choose the closest value greater than
the actual focal length of the lens. If you are using a Speedlight in this condition,
adjust the zoom head position manually.
Zooming with zoom lenses
• Lens data are not adjusted when non-CPU lenses are zoomed in or out. After
changing the zoom position, select new values for the lens focal length and
maximum aperture.
