Camera Test: Casio Exilim EX-Z100079767622206CasioEX-Z1000The 10.1-megapixel Casio Exilim EX-Z1000 (street $290) is the biggest member of the Exilim tribe in pure pixel power, but what do you get for all those extra pixels that you don't get in the 8MP EX-Z850 and 6MP EX-Z600 and S600? One thing is a very nice LCD layout option on the large 2.8" display, with all the technical details on the right rail, instead of atop the image. Ooh la la. The 3x zoom (38-114mm equivalent) Ex-Z1000 has excellent color accuracy, especially in manual mode, which Casio excels at throughout this line. You also get the eBay scene mode, which is in many Exilim cameras, but it seems a bit silly to buy a 10MP camera based on the fact that it can shoot low-resolution for the Web. You get very fast autofocus. It doesn't feel quite as fast as the 6-megapixel EX-Z600 and EX-Z600, but it is still surprisingly fast for a pocket camera. What you do not get is a major dramatic leap in resolution from the 8MP Exilim EX-Z850. At the lowest sensitivity, ISO 50, the EX-Z1000 only scores 210 points higher with a score of 1840, and at maximum ISO 400, the resolution is 1475, 85 points higher than the 8-megapixel model. Yes, that's right, the camera tops out at ISO 400; but it manages to keep noise at bay throughout this limited range. We'd rather see cameras with realistic ISO ratings to handle noise, rather than including high ISOs that the camera cannot actually handle.
