Sanyo Japan today announced two new 'Xacti' digital cameras, the four megapixel DSC-S4 and the three megapixel DSC-S3. These two entry level compact digital cameras have an identical body design and appear to utilize the same lens but because of the different size of the CCD in each the DSC-S4 only achieves 2.8x optical zoom compared to the DSC-S3's 3.0x optical zoom. The DSC-S3's price works out at around US$300, the DSC-S4 at around $380.
