Newly developed 7.5-Megapixel Live MOS sensor
The E-330 boasts a new image sensor that operates with lower power consumption,while maintaining superior image quality through its high-resolution, full-frame CCD. Compared to the conventional CMOS sensor, the optical aspect ratio produced by the Live MOS sensor in each pixel is larger, so photographic expression in more subtle tonal gradations is enabled, from the highlights to the shadows, and noise reduction has been enhanced. In addition, blue color reproducibility and the separation characteristics of the reds and greens have been greatly expanded. The vivid blues of the sky, the greens of foliage, and skin tones are accurately reproduced.

Reste à attendre les prochains tests pour voir si il ne s'agit que de "promesses de vendeur"...
En tous cas, le capteur CCD du E-300 fourni par Kodak ne tenait pas ses promesses pour les hautes valeurs de gain ISO.
