2 December 2005 -

A firmware update is now available for
the Olympus E-500 digital SLR. Changes to the previous version
include addition of a three-step adjustable button timer, a white
balance off option and a security mode to protect against the
unintentional erasing of both JPG and RAW versions of the one
image.

Dedicated to ensuring users enjoy the best possible photography
experience, Olympus now releases firmware version 1.1 for the
Olympus E-500 digital SLR. Improvements over the previous firmware
include:

# Button timer: Besides three and five seconds, photographers can
now increase the time interval between when a button is pressed and
when the camera reverts back to the current mode, to eight seconds.
This provides for more time to make necessary adjustment in
difficult situations and lets the camera be better customised to
personal preferences.

# Enhanced one-touch WB functions
In addition to one-touch WB, test picture, my mode and
preview -customers can now select WB OFF mode. By choosing this
function, the WB button is disabled in order to avoid any
unintentional activation.

# Security step
When erasing both RAW and JPG files of one image, a new security
step has been added. The camera will display a warning message to
alert users that both images will be deleted. This additional step
ensures data will not be lost unintentionally.

The Olympus E-500 version 1.1 firmware update is available now for
download. Simply open the Olympus Master software, connect the
camera via USB to the computer and log onto the internet. Choose
the Update Camera function from the Online Service menu in the
Olympus Master software and the update will be initiated
immediately.
