The Casio Z2000 was announced at the Consumer Electronics Show in early January, and is closely related to the Z2200 -- a model which the company hasn't actually announced or added to its product pages on its various global websites. The sole differences between the EXILIM Z2000 and Z2200 are related to their image sensors, with the Z2000 using a 1/2.3"-type 14.1 megapixel CCD imager, and the Z2200 dropping the sensor resolution ever so slightly to twelve megapixels. (The smart zoom function -- which essentially just crops the image -- also varies in strength slightly depending on the resolution). Each camera couples its respective imager to a 5x optical zoom lens, and offers a 3.0" LCD for framing and reviewing images. A reasonably generous 73.8MB of built-in memory is available in either camera, along with an SD / SDHC card slot. Power comes from an NP-110 rechargeable rated as good for 580 shots on a charge in either model.
The new firmware release for both cameras sees the version number boosted from v1.00 to v1.01, and Casio hasn't provided any information as to what's been changed, noting only that it has "improved certain operation". Casio Z2000 owners can get their firmware update here, while Z2200 owners will find their own update here.
