Like the J10, the J12 is an incredibly simple camera with a very basic specification. It has a 1/2.5-inch 8.2MP sensor, a 3x zoom lens with a focal length range equivalent to 38-113mm, and a rather small (by current standards) 2.5-inch LCD monitor with a fairly restricted viewing angle and a resolution of only 114k dots. It has none of the advanced features that we've come to take for granted, such as image stabilisation, contrast enhancement or face detection, or even basic things like a choice of metering modes or autofocus options. It practically goes without saying that of course it has no manual exposure or focusing functions.
User control is limited to a few simple menu options, including white balance, ISO setting, exposure compensation and burst mode. It doesn't even have a proper continuous shooting mode, offering instead a simple three-shot burst. However at least the menu system and the D-pad used to navigate it are less fiddly than on the previous model, and operate smoothly.
There's not much else I can say about this camera that wasn't already covered in my review of the J10. The zoom control is still a rocker switch and is still stepped, with six increments between minimum and maximum. Like most recent Fujifilm cameras it has a multi-purpose card slot that can take SD/SDHC as well as xD-Picture cards.
