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 Olympus E-PL8 and Panasonic GF8 side-by-side from the front, back and top in their relative dimensions. Olympus E-PL8 has external dimensions of 115 x 67 x 38 mm (4.53 x 2.64 x 1.5″) and weighs 357 g (0.79 lb / 12.59 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).

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 (91g ) than the Olympus E-PL8 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 both Olympus E-PL8 and Panasonic GF8 have the same Micro Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Olympus PEN E-PL8 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.
