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 F900EXR nor Canon PowerShot SD940 IS / Digital IXUS 120 IS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Fujifilm F900EXR's 3.00" LCD screen is slightly larger than Canon SD940 IS's 2.7" screen.
