Zoom : 12X Optical and 4X digital

Recently got my hand on the Canon Poweshot S5 IS camera. This camera is positioned as an 'SLR like' camera but not quite SLR. I found myself in one of the tall buildings in Noida, India and realised that this is a good test of zoom capability of this camera. Here is a series of pictures from the same place, in same direction, increasing the zoom with every picture.
