The Olympus E-300 is an 8 megapixel digital SLR
manufactured by Olympus
of Japan
and based on the Four Thirds System
. Announced at Photokina 2004, it became available at the end of 2004. It was the second camera (after the Olympus E-1
) to use the Four Thirds System, and the first intended for the consumer markethttp://www.shutterbug.com/test_reports/0505olympus/.
"hump". Instead, a Porro prism
system was used; it fitted sideways within the camera, with a sideways-swinging mirror, and located the viewfinder eyepiece to the left (seen from behind) relative to the lens centerline. The body was largely of ABS
plastic over a metal frame; the lens mount was metal, and there was a metal covered area on the left top of the camera. This area also contained the onboard flash, which popped up and forward at the touch of a button. The onboard flash popup mechanism is manual. In low light scenarios the flash will not pop up automatically but the photographer must press the button and pop it up before taking the photo.
The E-300 uses Olympus' patented Supersonic Wave Filter
dust reduction system
to shake dust from the sensor during startup and when requested by the user; this largely eliminates the problem of dust accumulation on the surface of the image sensor.
The E-300 was replaced by the Olympus E-330
, a similar model with live preview
, in January 2006.

Features
The camera's appearance was unique, as it lacked the ubiquitous SLR pentaprismPentaprism
A pentaprism is a five-sided reflecting prism used to deviate a beam of light by 90°. The beam reflects inside the prism twice, allowing the transmission of an image through a right angle without inverting it as an ordinary right-angle prism or mirror would.The reflections inside the prism are not...

Supersonic Wave Filter
The Supersonic Wave Filter is a dust reduction system developed by Olympus to overcome the negative effect of dust particles landing on the image sensor of digital SLRs. DSLRs are particularly vulnerable to this issue, since the interior of the camera is exposed during lens changes unlike other...
