Both Olympus and Panasonic agreed to develop technology and key components in accordance with the Four Thirds System and in January 2005. A mirror box unit and Live CMOS sensor is seen in both the cameras which takes the SLRS capabilities a step further. A quicreturn mirror, viewfinder, and AE sensor are all incorporated in the mirror box and the Live CMOS sensor offers image quality higher than the CCD sensor consumes powelower than a CMOS sensor. This makes viewing of images on the LCD last longer as low battery is consumed. The Olympus E-330 offesfull-time Live View framing via a rear-mounted LCD monitor and sports a style which is new to the digital world.

The Panasonic DMC-L1 uses Live MOS sensor and proprietary Venus Engine III image-processing LSI for high processing and greater image quality. It also combines the operational feel of an analog camera and is extremely user friendly.
