The camera does have a light sensor for metering that has it's own little window at the front of the camera.
There is no meter read-out as there is in most SLR's. There is no exposure information at all - except for a blinking light in the viewfinder if the exposure is going to be really long. It's an auto-everything P&S.
It does take excellent pictures, every bit as sharp and well exposed as I get with a Nikon SLR.
