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 Fujifilm X-A2 and Panasonic GF8 side-by-side from the front, back and top in their relative dimensions. Fujifilm X-A2 has external dimensions of 117 x 67 x 40 mm (4.61 x 2.64 x 1.57″) and weighs 350 g (0.77 lb / 12.35 oz) (including batteries). Panasonic GF8 has external dimensions of 107 x 65 x 33 mm (4.21 x 2.56 x 1.3″) and weighs 266 g (0.59 lb / 9.38 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm X-A2 and the Panasonic GF8. Panasonic GF8 is clearly the smaller of the two cameras. Its body is 10mm narrower, 2mm shorter and 7mm thinner than Fujifilm X-A2.
Here is the back view size comparison of the Fujifilm X-A2 and Panasonic GF8.
Now lets look at the top view comparison of Fujifilm X-A2 and Panasonic GF8.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic GF8 is significantly lighter (84g ) than the Fujifilm X-A2 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since Fujifilm X-A2 has an APS-C sized sensor and Panasonic GF8 has a smaller Four Thirds sensor, Panasonic GF8's lenses for a similar focal length and aperture will generally be lighter and smaller than the Fujifilm X-A2 lenses.
Weather Sealing
Unfortunately neither the Fujifilm X-A2 nor Panasonic Lumix DMC-GF8 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
