Weight is another important factor especially when deciding on a camera that you want to carry with you all day.

Unfortunately neither Panasonic Lumix DMC-FX48 (Lumix DMC-FX40) nor Sony Cyber-shot DSC-HX100V provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Sony HX100V's 3" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
In addition to the size advantage, Sony HX100V LCD screen also has a Tilting feature
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Panasonic FX48 has a fixed type screen which provides less flexibility in shooting positions compared to HX100V.
