Sometimes when I turn off the E-3, I feel a slight vibration or hear a
noise. Why is that?
When the camera is powered down, slight vibration and noise occur as the Supersonic
Wave Drive (SWD™) motor resets the image sensor to its default position. The E-3
takes this action when shooting with the Image Stabilizer function set to I.S. 1 or I.S.
2. In either mode, the camera moves the sensor during shooting in order to counter the
effects of camera shake. When the power is turned off, the camera moves the sensor
back into the default position.
When Image Stabilizer is set to OFF, the sensor does not move during shooting and
so does not need to be reset. However, if shooting with a zoom lens, some noise may
still be heard when the camera is powered off as the lens resets its focus to infinity.
If both Image Stabilizer and Lens Reset are set to OFF, the camera will power down
in silence.
What is the difference between the I.S. 1 and I.S. 2 image stabilizer?
In I.S. 1, the Image Stabilizer corrects for camera shake on both the horizontal and
vertical planes. In I.S. 2, the Image Stabilizer only corrects for vertical camera shake.
This is to allow a photographer to use a low shutter speed and pan horizontally for creative
effect. Situations in which this technique can be applied include tracking rapidly moving
subjects such as flying birds, running wildlife, racing cars, and athletes with the intention of
blurring the background for a visual effect in the image. The result would be a sharply
defined subject against a blurred background that might otherwise appear cluttered.
I have a lens from another manufacturer that has built-in optical
image stabilization. Will I get more image stabilization if I mount it
on the E-3 and enable its Image Stabilizer?
In such a scenario, it is recommended to use one or the other, but not both image
stabilizers simultaneously. If both lens and body image stabilization are being used at
the same time, the combination may be counter-productive because the camera image
stabilization would be trying to compensate for the lens image stabilization and not be
able to arrive at a stabilized image.
What are the P, A, S and M modes and how are they used?
The P, A, S and M modes are shooting modes. These modes allow the photographer
creative flexibility by enabling more control over shutter speed and f-stop settings. The
shooting modes enable total access to the menu options, unlike the AUTO and Scene
modes found in Olympus consumer DSLRs. They are also the modes required for use
with E-System flash accessories.
Briefly, the shooting modes and their applications are as follows:
•
P (Program shooting) – This mode allows shooting using an aperture and shutter
speed set by the camera. However, the Program Shift function allows some
creative control. When powered on with this mode selected, the E-3 displays P in
the upper left of the Control Panel screen. Rotating the main dial or the sub dial
changes the P to Ps, which is Program Shift. This permits the selection of a shutter
speed or aperture other than the default while maintaining the same exposure. If a
higher shutter speed is selected, a wider aperture will be set. If a slower shutter
speed is selected, a smaller aperture will be set. In effect, it is an AUTO mode that
accepts input from the photographer.
