Casio has added two new digital camera to its EXILIM Z-series but has hardly opened its mouth on the specs of both the cameras. The newly announced digicams are the Casio Exilim EX-Z7 and the Casio Exilim EX-Z6. Unfortunately, we are low on info about both the devices. All the little we know about the EX-Z7 is that is comes equipped with the standard 7.2-megapixel resolution, 2.5-inch TFT color screen, 3x optical zoom, an Anti-shake DSP to compensate for the camera shake. No words on pricing and availability. The EX-Z6 boasts 6-megapixel resolutions and comes rocking a 2.5-inch TFT color monitor with a 3x optical zoom lens. Well, it might also come stuffed with the Anti-shake DSP. But, we are really short on the details on both the cameras.
