Olympus E-510 DSLR Camera

The E-510 body and lens mount conform to the “Four Thirds System” standard, providing compatibility with other lenses for that system. Four-Thirds is a digital SLR standard using a crop factor of 2x; this means that Four-Thirds lenses can be made smaller and cheaper, but that the cameras exhibit somewhat worse high ISO performance.

As with all E-system cameras, the E-510 uses Olympus’ 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.
