The “B” setting is useful in flash photo
graphy for lightening the subject’s back

Flashes other than the Canon Speedlites
When flashes other than the four special
Canon Speedlites are used with the A-1, the
digital readout will include the same infor
mation as in manual override. See p. 65.
However, since the aperture displayed has no
meaning in this case, it might cause less con
fusion to switch off the viewfinder display
lever.
