Casio have rather confusingly released not one, but two firmware updates for the 8.1 megapixel EX-Z850 camera. You can now choose from either v1.10, which just adds SDHC memory card support, or v1.1B, which also includes better HQ Mode movie quality, but with a 40% narrower field of view angle than the previous firmware version. Choices choices…

V1.10
SDHC memory card support
The field of view angle or image quality of this version is the same as the previous firmware version.

V1.1B
SDHC memory card support
Better HQ Mode movie quality (less digital noise, smoother lines) than the previous firmware version
Approximately 40% narrower field of view angle than the previous firmware version for HQ Mode

Differences between Version 1.10 and Version 1.1B
Version 1.1B HQ Mode movie quality is better, with less digital noise and smoother lines than the previous firmware version. This update also makes the field of view angle 40% narrower than the previous firmware version.
Version 1.10 does not affect HQ Mode movie quality or the field of view angle.
