I'm so disappointment. Last week, I bought a Panasonic Lumix DMC-FX33. Really excited about it. But the pictures from this weekend let me down. It's a known issue that the image quality is a little low, but I didn't realize that it could be so low that my untrained eyes could tell the difference easily. Following are two pictures of the same tree, one taken by my Panasonic and the other by our Olympus. Granted, they are not exactly the same image, but it seems obvious that Olympus is able to bring up a lot more details than Panasonic.

Following is one of my favorites:

This is as good as I could get by using the Scenery mode. The one from IA Auto mode (which I mostly use for its simplicity) is worse. We would have been able to get a crystal clear shot of the ridge line with the Olympus.
Fortunately, the vendor where I bought it from is a reputable one and has no problem with giving me full refund for my return. But that puts me back in the position of camera shopping (I hate shopping!). What should I get now?
I have been looking into Canon PowerShot SD870IS. But now I don't know what to believe when I read the reviews (the reviews for Lumix DMC-FX33 were pretty good too).
What I'm looking for: small, light weight, good at taking action shots, and good at low light conditions (for riding in forests, e.g.)
What I do not care about: Mega Pixels (I never crop pictures, no time for it), size of LCD screen
F'ueco? F4?
