Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic ZS1 and Canon G11 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS1 has external dimensions of 103 x 60 x 33 mm (4.06 x 2.36 x 1.3″) and weighs 229 g (0.50 lb / 8.08 oz) (including batteries). Canon G11 has external dimensions of 112 x 76 x 48 mm (4.41 x 2.99 x 1.89″) and weighs 375 g (0.83 lb / 13.23 oz) (including batteries).

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS1 is significantly lighter (146g ) than the Canon G11 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Canon PowerShot G11 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G11's 2.8" LCD screen is slightly larger than Panasonic ZS1's 2.7" screen.
Moreover, Canon G11 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Panasonic ZS1 has a fixed type screen which provides almost no flexibility in shooting positions compared to G11.
