Maybe users of Canon and Lumix can post their photos down here as well and we can do a comparison in this thread. Of course, there are different ways of taking the photos and at different settings, but just for reference yah.
Taken with my old FZ50 (which I sold away already). My verdict is that FZ50 gives good coulours in well lit conditions and has good IS. Reasons I switched to DSLR were the shutter lag and poor ISO performance of the prosumers.
Larger versions of the photos below can be found in my Flickr account. The FZ50 photos and D80 photos in my flickr are all together so you may have to look at the picture info to differentiate them.
