Just as I was done shooting with the HS10, Fujifilm released a
firmware update to improve sharpness as well as a couple other issues. This is after the update, which takes only a few seconds to do and is as easy as downloading the file, putting the file on an SD card, inserting it in the camera, and pressing a couple buttons. The update seems to have only made a slight improvement to sharpness, most noticeable at ISO 400-1,600. (Though it seems to have increased color noise above these sensitivities.) It doesn't turn it into an entirely different camera, but the update is worth doing.
