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

Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-ZS45 (Lumix DMC-TZ57) nor FujiFilm FinePix JZ300 (FinePix JZ305) 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 ZS45's 3.00" LCD screen is slightly larger than FujiFilm JZ300'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, FujiFilm JZ300 has a fixed type screen which provides less flexibility in shooting positions compared to ZS45.
