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, select exposure mode g or
h and set aperture using the lens aperture ring.
In other modes, the
shutter-release is disabled.
Non-CPU lens data (0 212) 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.
