Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FX48 is 17g lighter than the Sony S950 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither Panasonic Lumix DMC-FX48 (Lumix DMC-FX40) nor Sony Cyber-shot DSC-S950 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Sony S950's 2.7" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
