Thanks for all your comments. I have tried all kinds of settings but cannot get any sharper shots. It was a little hazy, but not too bad that day (Hong Kong is always hazy!). Do you think maybe there's something wrong with my camera? Or could it be due to the fact that I was shooting with max zoom (i.e. 10x at 370mm)? (I use Canon's Pro90, settings were exposure compensation -1/3, saturation high, sharpness and contrast normal).
