Re: slightly off-topic...or not (re cameras)
I have a Lumix DMC-FX07, 7 Megapixel. It has a very nice Leica lens attached. The most useful facility (and this is why I bought it) is that it has a black and white mode. I use this for checking tonal values and relationships before hauling out the 5x4 or 10x8. It also has a reasonably sized histogram facility which helps. Only records in JPEG however.
