Casio has updated the firmware for the Exilim EX-Z700 (top photo, above) and EX-70 (bottom) to provide support for the new high capacity SDHC memory cards that currently tops out at 8GB.
The new firmware (Version 1.01) will enable the EX-Z700 and EX-Z70 to accept SDHC cards with capacities of 8GB and beyond.
Firmware is a neat way to enhance the functionality of a device by updating its software instead of tweaking its hardware.
If you own these cameras, you may download the firmware updates from here: EX-Z70, EX-Z700.
