Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Panasonic LX100 and Canon SX270 HS side-by-side from the front, back and top in their relative dimensions. Panasonic LX100 has external dimensions of 115 x 66 x 55 mm (4.53 x 2.6 x 2.17″) and weighs 393 g (0.87 lb / 13.86 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX270 HS is significantly lighter (160g ) than the Panasonic LX100 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LX100 nor Canon PowerShot SX270 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Panasonic LX100 and Canon SX270 HS's LCD screens have the same diagonal size of 3.00 inches.
