Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS30 is significantly lighter (56g ) than the Sony HX30V which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS30 (Lumix DMC-TZ40) nor Sony Cyber-shot DSC-HX30V provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Panasonic ZS30 and Sony HX30V's LCD screens have the same diagonal size of 3.00 inches.
