A Lens f-number
The f-number given in lens names is the maximum aperture of the lens.
A Compatible Non-CPU Lenses
When using non-CPU lenses and accessories, rotate the camera mode dial to A or M and set
aperture using the lens aperture ring. In other modes, the shutter-release is disabled. Non-
CPU lens data (0 149) can be used to enable many of the features available with CPU
lenses, including color matrix metering; if no data are provided, center-weighted metering
will be used in place of color matrix metering, while if the maximum aperture is not
provided, the camera aperture display will show the number of stops from maximum
aperture and the actual aperture value must be read off the lens aperture ring.
