Picked this up somewhere - the Nikon D2H allows the usage of non-CPU lenses.
Quote:-
Another new feature on the D2H is the ability to enter data in the shooting menu when using a non-CPU Nikkor lens. Inputting information about the attached non-CPU lens (i.e., focal distance and aperture number) enables the following functions with these types of older Nikkor lenses:
Functions that are available after inputting the focal distance: Automatic zooming of the speedlight; displaying of the focal distance in the playback screen (focal distance is marked with an asterisk).
Functions that are available after inputting the aperture setting: Display of the lens' aperture setting (on the top control panel and in the lower part of the viewfinder); automatic external flash control linked to the aperture setting; aperture setting display in the playback screen (aperture number is marked with an asterisk).
Functions that are available after inputting both the focal distance and aperture setting:
RGB multipattern metering; 3D Multi-Sensor Balanced Fill-Flash.
The lens information can be entered in the "lens information manual setting" of the shooting menu, or by using the function button and main control dial
Available focal distance settings: 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, 1,000, 1,200, 1,400, 1,600, 2,000, 2,400, 2,800, 3,200 and 4,000mm.
Available aperture settings: 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 and 22.
