The Panasonic Lumix DMC-FZ10 is no better nor worse than the Olympus C-750 in terms of purple fringing. At my office we tested my Panasonic FZ10 against an associate's Olympus C-750 and both ultra zooms did great....yes purple fringing was there on both cameras...but it can be compensated for by using Aperture Priority or Manual mode and setting the lens on both camera to f4 or smaller. I like the image stablized Leica lens of the Panasonic as it yields consistantly sharper images than my associate's Olmpus C-750 but if both cameras were on a tripod and timer I would say they are equally great at taking images.

As far as finding the Panasonic Lumix DMC-FZ10 in stores...its a lot harder to find. I eventually found mine at a local Ritz Camera shop...but had to order the extra proprietary batteries online as the local store didn't have any.
