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 FS15 and Fujifilm XQ2 side-by-side from the front, back and top in their relative dimensions. Panasonic FS15 has external dimensions of 97 x 54 x 22 mm (3.82 x 2.13 x 0.87″) and weighs 136 g (0.30 lb / 4.80 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 Panasonic Lumix DMC-FS15 nor Fujifilm XQ2 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
Fujifilm XQ2's 3.00" LCD screen is slightly larger than Panasonic FS15's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
