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 HS20 EXR and Olympus PEN-F side-by-side from the front, back and top in their relative dimensions. FujiFilm HS20 EXR has external dimensions of 131 x 91 x 126 mm (5.16 x 3.58 x 4.96″) and weighs 730 g (1.61 lb / 25.75 oz) (including batteries). Olympus PEN-F has external dimensions of 125 x 72 x 37 mm (4.92 x 2.83 x 1.46″) and weighs 427 g (0.94 lb / 15.06 oz) (including batteries).
Below you can see the front-view size comparison of the FujiFilm HS20 EXR and the Olympus PEN-F. Olympus PEN-F is clearly the smaller of the two cameras. Its body is 6mm narrower, 19mm shorter and 89mm thinner than FujiFilm HS20 EXR. As you can tell, actually this is not a fair size comparison since FujiFilm HS20 EXR has a built-in lens but Olympus PEN-F doesn't. Once you put a lens on PEN-F, its thickness will increase significantly.
Here is the back view size comparison of the FujiFilm HS20 EXR and Olympus PEN-F.
Now lets look at the top view comparison of FujiFilm HS20 EXR and Olympus PEN-F.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus PEN-F is significantly lighter (303g ) than the FujiFilm HS20 EXR 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 PEN-F, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the FujiFilm FinePix HS20 EXR (FinePix HS22 EXR) nor Olympus PEN-F 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 HS20 EXR and Olympus PEN-F's LCD screens have the same diagonal size of 3.00 inches.
FujiFilm HS20 EXR features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Olympus PEN-F sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
