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 G6 and Panasonic FP2 side-by-side from the front, back and top in their relative dimensions. Panasonic G6 has external dimensions of 122 x 85 x 71 mm (4.8 x 3.35 x 2.8″) and weighs 390 g (0.86 lb / 13.76 oz) (including batteries). Panasonic FP2 has external dimensions of 99 x 59 x 19 mm (3.9 x 2.32 x 0.75″) and weighs 151 g (0.33 lb / 5.33 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic G6 and the Panasonic FP2. Panasonic FP2 is clearly the smaller of the two cameras. Its body is 23mm narrower, 26mm shorter and 52mm thinner than Panasonic G6. As you can tell, actually this is not a fair size comparison since Panasonic FP2 has a built-in lens but Panasonic G6 doesn't. Once you put a lens on G6, its thickness will increase significantly.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FP2 is significantly lighter (239g ) than the Panasonic G6 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on G6, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-G6 nor Panasonic Lumix DMC-FP2 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
Panasonic G6's 3.00" LCD screen is slightly larger than Panasonic FP2's 2.7 screen.
Moreover, Panasonic G6 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 FP2 has a fixed type screen which provides almost no flexibility in shooting positions compared to G6.
