Since you like 24mm, that's going to make finding a camera a lot easier. I've owned the Ricoh GX100 & GX200, but they're long in the tooth now. Lumix FX6 is 25mm and cheap. Casio Exilim EX-H10, H15 and FH100 are all 24-240mm. Sony W380, WX1 are bright f2.4 lenses.Canon 10S, 930S but I've not used them. The lightest by far would be the Sony W380, I think. Lumix LX3 is brightest at f2??
I'm sure there's other 24mm cameras out there, but I bet I've named nearly half of them. You should be sure to play with a Casio Exilim, preferably the Exilim FH100, whatever you end up buying in the end. Model numbers may be different in your part of the world.
