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

Panasonic S1 has external dimensions of 99 x 59 x 21 mm (3.9 x 2.32 x 0.83″) and weighs 117 g (0.26 lb / 4.13 oz) (including batteries).

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 Canon PowerShot S110 nor Panasonic Lumix DMC-S1 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 S110's 3.00" LCD screen is slightly larger than Panasonic S1's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
