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 S9900w and Olympus PEN-F side-by-side from the front, back and top in their relative dimensions. Fujifilm S9900w has external dimensions of 123 x 87 x 116 mm (4.84 x 3.43 x 4.57″) and weighs 670 g (1.48 lb / 23.63 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 S9900w and the Olympus PEN-F. Olympus PEN-F is 15mm shorter and 79mm thinner than Fujifilm S9900w but it is also 2mm wider. As you can tell, actually this is not a fair size comparison since Fujifilm S9900w 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 S9900w and Olympus PEN-F.
Now lets look at the top view comparison of Fujifilm S9900w 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 (243g ) than the Fujifilm S9900w 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 S9900w 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 S9900w and Olympus PEN-F's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus PEN-F 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. Fujifilm S9900w's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to PEN-F.
