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

Weather Sealing
Thanks to the weather-sealed body of the WG-1 GPS, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the ZS45.
LCD Screen Size and Features
Panasonic ZS45's 3.00" LCD screen is slightly larger than Pentax WG-1 GPS's 2.7" screen.
In addition to the size advantage, Panasonic ZS45 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, Pentax WG-1 GPS has a fixed type screen which provides less flexibility in shooting positions compared to ZS45.
