The comfort and flexibility of continuous live previews directly on the
LCD is available to digital SLR users for the first time. This
ground-breaking innovation - which started with the E-330 enables
framing of shots without the need to look through the viewfinder. Users
can therefore see what’s going on around them while they shoot and also
use the camera in situations where it is difficult to frame using the
viewfinder. This means that macro photographers needn’t lie in the mud
to frame ground-level subjects any more, and portrait photographers can
keep constant eye contact with their model or client. It makes
capturing shots from unusual angles, such as in crowds, effortless.

Fulltime Live Preview |
Fulltime
Live View utilises a second image sensor mounted in the viewfinder’s
optical path to transfer the image to the 2.5”/6.4cm multi-angle LCD.
Because this CCD is placed after a half transmissive mirror, then the
view via the optical view finder is also available. So, depending of on
the shooting environment, the photographer can choose which viewing
option to use. Because the side swinging mirror will stay in the usual
position full AF functionality is available.
Especially for portrait photographers, two passport frames are incorporated for perfect framing.

Support for sure exposure correction |
Until
now, it was impossible to check the results of exposure correction
before taking the picture, but Live Preview has made it possible. As
this function allows the user to confirm the correction effect
intuitively, even users with no knowledge of exposure can easily
exploit the advantages of SLR shooting. Those users who are familiar
with exposure correction can also benefit since it will allow them to
make adjustments more quickly while viewing the LCD monitor, without
having to check the white balance after every shot.

Macro Live Preview |
The
Macro Live View locks the mirror in the up position and uses the
camera’s Live MOS sensor to enable a Macro Live View with a 100% field
of view. This mode is especially helpful for visual focusing on macro
subjects, providing the freedom of complete manual focus control via
the main Live MOS Sensor. A selected section of the image can be
enlarged by 10x to ensure focusing accuracy.

How Live View works |
Live
View is made possible by moving the mirror upwards and displaying the
image on the LCD at the back of the camera as the image sensor “sees”
it. Both automatic and manual focusing modes are supported. For
autofocus, the mirror is flipped down momentarily and then - once the
AF sensor which sits behind the mirror has taken its reading - back up
again.
With Live View in operation, the image sensor is
permanently ON, so a type of sensor was needed that consumes little
power while at the same time delivers the high image quality of the
Full Frame Transfer CCD. Olympus incorporated a proven Live MOS sensor
technology, and then simplified the sensor construction by radically
improving the materials and processing technology. The result is a
sensor with low power consumption as well as low heat and noise
generation. Enjoy Generation 2 of the Olympus E-System! |
