Canon A-1 - Manual (Page 7)

Wide Metering Range
With its extensive film sensitivity range
(ASA 6-12800) and 16 shutter speeds
(1/1000-30 sec.), the A-1 offers a wide AE
metering range from EV18 (f/16, 1/1000
sec.) all the way down to EV-2 (f/1.4, 8 sec.)
with ASA 100 film and an f/1.4 speed lens.
Provided that you can even focus your
subject in the viewfinder in a very dark
situation, it is most likely that you will be
able to meter it as well, even in an AE mode.
This is especially advantageous in such
dimly-lit situations as those in night scenes
and photomacrography.
Other Special Features
Add to these features the A-1's single-lever
multiple exposure operation and its two-
interval self-timer with an LED warning.
Switching one small lever before winding the
film sets the A-1 for a multiple exposure.
The film and even the frame counter remain
stationary for unlimited multiple exposures.
You can set the self-timer for a time-lag of
either two or ten seconds during which an
easily visible LED flashes. Flashing frequen-
cy increases as a warning prior to shutter
release.
Finally, seemingly small features, but big
advantages in photography, include the A-1's
detachable action grip, its 120°-stroke film
advance lever with a 30 stand-off, its
eyepiece shutter and its shutter button lock
(main switch).
The System
Beginning with accessories which are integral
parts of the A-1 system, Canon offers the
Speedlite 199A and the Motor Drive MA.
Either the specified Canon Speedlite 577G,
533G, 199A, 188A, 177A, 155A or 133A
can be mounted on the A-1 for AE flash
photography with automatic setting of
shutter speed and aperture. With the Motor
Drive MA, continuous shooting at up to five
frames per second is possible, and the A-1
also accepts the Power Winders A and A2.
Like the AE-1, the A-1 can also use the
Data Back A, a date imprinting mechanism
that will couple to both power winder and
Speedlite. Plus, you have your choice of
accessories from Canon's extensive SLR
system. From its famous, high resolution FD
lenses to its complete line of systemized
accessories for close-ups, photomacrography
and photomicrography, Canon offers high-
quality equipment for all photographic
fields.
