Samsung's ST550 has received plenty of attention for being the first compact camera to have a second LCD display on the front. But this is only one of a number of highly innovative features that make this £250 snapper much more interesting than the average 12.2-megapixel compact.
We've got to start with that second LCD display, and we're pleased to say that it's not just a gimmick. Anyone who's tried setting up a self-portrait will know how difficult it is to come up with a good shot when you can't see your expression, or your hair's gone wrong, or your thumb's in the way of the lens. It really is quite a novelty to be able to see what you and your companions look like as you set up the shot. Just point the camera towards you, then tap the front to activate the display. That tap also activates the face-detection system.
That's not all this extra display does. It can display a countdown when you're using the self-timer, show an animated cartoon to distract very small children while you're taking their picture, and even tell your subjects when to smile, by displaying a smiling face when you press the shutter button halfway down.
We've all managed without front-mounted LCDs until now, but the ST550 demonstrates that something that might sound like a pointless gadget can actually be extremely useful.
It's round the back that the ST550 is really interesting, though. It has a whopping, 89mm (3.5-inch) touchscreen interface with a difference. It's a 'haptic' display that produces a vibration when you activate an icon. This makes for a much more tactile experience than usual.
