I-R review in ZS20/TZ30 is up.
Some of these reviews nitpick the most ridiculous little things. Some of the "cons" they list are seriously non-issues for most people. I love this little camera; particularly its form factor. Is it a substitute for my Canon 40D? Of course not. Is the image quality of the ZS15 a bit better? Perhaps so, but not so much that you'd even notice it unless you're pixel peeping. But I think it's PERFECT as a pocketable/vacationing camera.
