Patent 2011239020 from Ricoh is for a GXR unit with image stabilization:

Patent 2011232461 filed by Canon in Japan is for calculating the flash shooting distance based on the color temperature. From the patent application:

With the strobe device used as a light source, the guide number had determined the flashing tube by main capacitor energy. Therefore, the operation and the display were able to do easily range of the sensitivity (gain) which is the film information of a camera, and the strobe light which becomes correct exposure according to a diaphragm of a lens. Therefore, since a user was made to know range before speed light photography, it was able to reduce that underexposure occurred in a taken image.

    Sorry, it’s fixed now – the site was not hacked, just my own stupidity. You may have to refresh your browser to get the latest version/update.

    The 10/12mm Olympus patents just seem to be variations on a theme – they chose the 12/2, so don’t wait with baited breath for a 10mm ultra wide.
