EXPO SURE C OMP ENSA TIO N You can, of cours e, m ake exp osure cor- recti on s by operating the ca mera manually, but the A- 1 is als o e quipp ed wi th oth er devices which allow you t o co rr ect th e exposure w hile in an A E mod e.

Exposure M emory Sw itch The A- 1 also off ers an exposure m e mory switch f or correcting the exposur e in the AE mode. Essentially, this switch assures cor rect exposure by e xposing the p ict ure f or your subject no matter what the surround ings are.
Cha ngi ng the A SA Se t ting There is another way to correct exposure which can be used whether you ar e in the manual or the AE m ode. That is to change the ASA film speed set ting on the camera. A film with an ASA r ating twice that of another f ilm requir es only half t he amount of li ght for corr ect exposure as com pared with the other film.
Mult iple Exposures Making two or more exposures on the same fram e is an exciting technique which is very sim ple to per form with the A - 1 . After m aki ng the fi rst expos ur e, do not tur n the f il m advance le ver but r etur n it to its r et ract ed position clos e to the cam e ra bod y .
Multiple exposures are not possible when the Motor Drive MA or Power Winder A or A2 is mounted on the A- 1 and in operat ion. They ar e possible even when these accessori es a re mounted if you switch the m of f and advan ce the film manually.

This will p robably be one of tho se occasi ons when you will r elease the stop-down lever and return the lens to “A” b efore taking a shot.
Lens Signal Coupling There ar e several levers and pins at the r ear of an FD lens which tr an smi t signals be- tween the lens and the ca mera body. Usually it is not necess ary to know what they ar e , but someti mes, when you mus t operate t he aperture manually for non -coupled acces- sorie s fo r in stan ce , it i s.
