FLASH PHOTO GROUP
Flash is your own private "sun" when you take
pictures at night, indoors, or outdoors for day-
light fill-in. At the moment of flash, you can even
catch the movement of subjects that your own
eyes are unable to follow.
At present the OM System Flashphoto Group ren-
ders choice of 5 different flash units, including
the Electronic Flash T32 and T20. TheT32 offers
high performance — a maximum ASA 100 guide
number of 32 (in meters) or 104 (in feet) with an
angle that virtually covers the picture area of a
24mm super-wide angle lens, and is provided with
a built-in bounce mechanism. The T20 is extreme-
ly compact and features a maximum ASA 100
guide number of 20 (in meters) or 66 (in feet)
with an angle that covers the picture area of a
35mm wide angle lens. The T32 (or T20), when
used with the OM-2, is an OTF (off-the-film) ful-
ly automatic electronic flash unit. Even the dial
settings (auto/manual switching, aperture setting
and ASA film speed setting) required of conven-
tional "auto" flash units are unnecessary. By re-
versing the back plate of the flash unit, it can be
used as a normal auto/manual flash unit for use
with the OM-1, permitting 3 aperture values of
F4, F5.6 and F8 (with T20, two apertures of F4
and F8) at ASA 100 for normal auto flash as well
as two manual settings — GN16 (on T32 only)
and GN32 (GN 20 with T20).
