Thank you for the link kbrog : it was very useful partly because of pictures examples. There's also a review about FZ35. I think it's always better to compare reviews from the same source.

In fact, it seems that both cameras can use filters and that a cheap adapter would allow me to use my old ones. So I've no good reasons to stick to Fujifilm which seems "behind" the two other candidates.

To charge the batteries in a car, a simple cable, that I own yet, is enough. That was my biggest concern with the Lumix, because I shoot a lot when wandering. Its lens semmes better than Canon, and it produces RAW files. It has no plug for external flash, but with 1600 ISO and stabilisation, is it really a problem ?
