Size and weight are big decision factors when you are trying to find the ideal camera for your needs.

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 FujiFilm FinePix F70EXR (FinePix F75EXR) nor Canon PowerShot G15 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
Canon G15's 3.00" LCD screen is slightly larger than FujiFilm F70EXR's 2.7" screen.
