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 Canon SX620 HS and Leica Q-P side-by-side from the front, back and top in their relative dimensions. Canon SX620 HS has external dimensions of 97 x 57 x 28 mm (3.81 x 2.24 x 1.1″) and weighs 182 g (0.40 lb / 6.42 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 SX620 HS nor Leica Q-P provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Canon SX620 HS and Leica Q-P's LCD screens have the same diagonal size of 3.00 inches.
