Which camera, Canon or otherwise, would be one step down from, or the immediate technological predecessor to, the S90?
i.e. ultra compact, good high ISO and low light capability, preferably can shoot in RAW, and with manual controls.
Ultra-compact is the main requirement. Canon G series and Leicasonic LX3 are too big.
The point is: what's the closest thing to the S90 for less money?
