The photo quality from the ZS5 is very good with the understanding that this is a compact camera--regardless of its features. Photos shot at ISO 80 and 100 are great, they're sharp with nice color and fine detail. When you jump to ISO 200, photo subjects get slightly softer, but the images are still very good. At ISO 400, noise starts creating color issues including yellow blotching, though detail remains good. When you go up to ISO 800, its photos get pretty bad; they're soft and yellowy with visible noise. Forget about using ISO 1,600 unless you're shooting in black and white and don't mind graininess. In other words, if you're looking for great low-light photo quality or if you typically do a lot of heavy cropping, the ZS5 will disappoint you.
