Canon A-1 - Manual (Page 91)

DATA BACK A
Within seconds, the A-1's back cover can be
exchanged for the Data Back A, which,
again, becomes an integral part of the
camera's electronic system. As you press the
shutter release, the day, month and year will
be recorded clearly but unobtrusively in the
lower right hand corner of every picture, i.e.,
unless you decide to leave it blank. Since
letters and Roman numerals are also avail-
able, the Data Back can serve as a convenient
coding system as well.
Various Accessories for Close-ups
and Photomacrography
Canon offers a whole gamut of accessories
which give you unlimited possibilities in
close-ups, photomacrography and photo-
micrography. At the center of the system
stands the elegant, versatile Auto Bellows
featuring a built-in focusing rail, immediate
lens reversal and automatic diaphragm
coupling with the Canon Double Cable
Release. For higher magnifications with
excellent image quality there are the special-
ly aberration-corrected Macro and Macro-
photo lenses. A Macro Stage and four
duplicators provide the maximum of ease in
shooting difficult subjects.
Of course, close-up lenses and reversing rings
are also offered along with three sets of ex-
tension tubes. The remarkable set of exten-
sion tubes FD-U permit full-aperture meter-
ing, automatic diaphragm coupling and AE
photography with the A-1. There is also a
Bellow FL. Even with manual accessories,
the Macro Auto Ring and Double Cable
Release preserve automatic diaphragm coupl-
ing. Canon's extra-large, ultra-stable Copy
Stand 5, the smaller Copy Stand 4, a small,
collapsible copy stand, camera supports, a
Focusing Rail, cable releases and micro-
scope adaptors round out Canon's up-to-
date, integrated, comprehensive close-up
system.
