Sony has today announced a couple of updates to its T-Series of slim digital cameras, replacing the DSC-T100 and DSC-T20. First off we have the DSC-T200 with 8.0 Megapixels and 5x optical zoom. Taking up pretty much the whole of the camera's rear we find a 3.5" touch screen which may be used to choose between focus targets identified by the Face-Detection system. Sony also has an interesting twist on this now-common feature - smile detection! The DSC-T70 carries mostly the same specification but downsizes the zoom and monitor to 3x and 3.0" respectively.
