The OM system has a get back to basics ideology, of-
fering what we feel are the best optics, metering and
user features to give the photographer the ability to
achieve their own creative ends. These OM cameras are
for those who feel that to truly create the image you
desire, you need to control all the variables.
The rugged and durable titanium bodies of the OM4Ti,
OM4T and OM3Ti are backed by a group of 37 Zuiko
Lenses, a variety of Flashes, Drives, and other accesso-
ries. They give the photographer the perfect light weight
camera for their photographic applications. Both Cam-
eras offer the superior TTL/OTF Flash system pioneered
by Olympus, plus multi-spot metering, average meter-
ing, highlight and shadow compensation, and manual
exposure controls. The OM4Ti and OM4T also offer
OTF metering and spot and multi-spot metering in the
automatic mode.
The OM3Ti, OM4Ti and OM4T use an advanced flex-
ible exposure control system. When pressing only the
shutter button, the meter system used to take a picture
is the average center-weighted meter. Although the cen-
ter- weighted meter is excellent for general daylight ex-
posures, it may not meet the needs of every photographic
situation. To overcome difficult exposure situations,
Olympus added spot metering to these OM cameras.
Reading only 2% of the image area this metering sys-
tem is one of the most accurate meters on the market
today.
Taking the advantage of spot metering to the next level
Olympus allows the photographer the ability to read
and use multiple-spot meter settings. By reading mul-
tiple areas of the image, total creative control for each
individual image is returned to the photographer. These
OM cameras can take up to 8 spot readings, indicating
with a diamond dot above each reading on the
viewfinder graph. When faced with a particularly tough
2
light condition, the multi spot metering system is the
answer.
All meters are designed to read light as an 18% gray,
which works well most of the time. Film has approxi-
mately a 5 stop exposure range from black to white,
with 18% gray being at the theoretical center of this
exposure range. When photographing white or black,
the meter tries to adjust to gray causing the camera to
over or under expose. To overcome this inherent prob-
lem, Olympus added highlight and shadow exposure
controls to these OM cameras.
When photographing a white or a bright subject the high-
light control is used in conjunction with the spot meter
of the camera.Highlight adjust the exposure by +2.3
stops giving you white with detail.
Without using the highlight control, the camera under-
exposes by the same 2.3 stops creating a gray appear-
ing image.
The situation is reversed when photographing black, the
meter will over expose by 2.6 stops. Like a white or
bright subject, the cameras metering will result in a gray
appearing image. The shadow control automatically
adjusts the exposure by -2.6 stops creating rich black
with detail.
The OM 4Ti, OM4T and 3Ti also have an exposure com-
pensation dial, allowing over and under exposure con-
trol from +2 to -2 stops in 1/3 stop increments. This
control can be used with either the center-weighted or
spot meters for creative control.
The dedicated flashes for the OM system also work with
the unique OM metering system to allow flash expo-
sure through the lens. The TTL flash system works with
all the T series OM flashes and the F-280 OM flash. By
reading the light striking the film the camera gives the
most accurate flash exposures, even in difficult expo-
sure situations, with a variety of apertures. This Meter-
ing advantage works on the OM3Ti in the Manual TTL
flash mode and in the automatic exposure mode on the
OM4T and OM4Ti.
The OM4T, OM4Ti, and 3Ti also feature High speed
full syncro flash with the F-280 flash. When connected
to these cameras the flash offers flash synchronization
from 1/60 second to 1/2000 of a second, as well as nor-
mal TTL flash at 1/60 second. The Super FP flash mode
with its long duration flash is designed for fill in flash,
3
close up photography or to create flash and motion at
the longer 1/60 second exposure.
These OM bodies also have a viewfinder designed for
accurate image reproduction. Matched to a mounted
transparency and being 100% centered and 97% of the
image area, they are ideal when you need the accuracy
of “what-you-see-is-what-you-get” with your SLR.
Both the OM 4Ti and 3Ti also have easy to read LCD’s.
In the automatic mode on the OM4Ti and OM4T you
see a shutter speed scale from 1 to 1/2000 second, with
an LCD bar made of rectangles indicating the existing
exposure. The Diamonds indicate spot exposure read-
ings, automatically averaged by the camera. When used
in the manual mode or with the OM3Ti you will see the
selected shutter speed, with a pair of arrows and the
same broken LCD bar, indicating when you have a cor-
rect exposure.
