Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FX78 is 14g lighter than the Pentax W80 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the W80, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the FX78.
LCD Screen Size and Features
Panasonic FX78's 3.50" LCD screen is slightly larger than Pentax W80's 2.5 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
