Olympus has revamped its Four Thirds system E-500 and E-400 digital SLRs to reveal the 10-million-pixel E-510 and E-410, each featuring a Live MOS sensor.

Olympus has also confirmed to AP that the long-awaited successor to Olympus?s E-1 pro-spec model will be launched in ?late summer? following an announcement due to be made as we went to press. However, a spokesman would not comment on speculation that this will be called the ?E-2?.

Revealed just days ahead of the PMA photo trade show in Las Vegas is the E-510 (pictured)which will cost around £600 (body only). It will also come in a kit with a 14-42mm lens priced around £700 and with both a 14-42mm and 40-150mm lens in a kit costing around £800.

While, the E-410 will carry a body only price tag of around £500; or £600 including a 14-42mm lens; and around £700 for the double zoom kit.

Unlike the E-410, the E-510 boasts an ?electromechanical? image stabilization feature (?sensor-shift? type) which moves the image sensor to help compensate for any camera shake detected by the camera?s ?gyro sensors?.

Both models have Hi-Speed USB connectivity for downloading images and a new ?faster? image processing engine (TruePic III) compared to previous models, designed to deliver ?excellent noise performance?.

The cameras are not due out in the UK until June.

Full details will appear in an upcoming issue of AP.
