I'm also not massively impressed by the other controls. As I mentioned, the buttons and the tiny D-pad are squashed together at the right-hand end of the rear panel, and the position of the video recording button the one with the red dot in the picture below) means that it's very easy to press it accidentally. The buttons are also poorly labelled, with symbols etched into them. Chrome etching on a chrome button is difficult enough to make out in good light; in dim lighting it's almost impossible to see.
In terms of its main features, the Z1 represents something of a step backwards from the fairly sophisticated recent models like the Z80 and Z85, and is closer to the much simpler Z19. It has the usual handy side bar shooting menu, with quick control over common shooting settings, including image size, flash mode, ISO setting, white balance and exposure compensation. Naturally it has Casio's Best Shot scene mode function, with no less than 23 scene programs, however it lacks advanced features such as the auto-shutter system, high speed shooting or any sort of mechanical image stabilisation. All it has is an auto ISO-boost, which helps to counteract camera shake by increasing the shutter speed.
It does a good face detection system, but again it lacks the Friends and Family face recognition found on some other models. The video mode also looks a bit mediocre compared the HD video and high-speed recording of models like the FC100, with a maximum resolution of 640 x 480 at 30fps, although it does have a YouTube mode, and the supplied software includes a YouTube uploader. I'm not sure that this is a big selling point though, since as far as I know YouTube will accept video clips in a wide range of formats, and also has its own uploader.
