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 F660EXR and Olympus E-P5 side-by-side from the front, back and top in their relative dimensions. Fujifilm F660EXR has external dimensions of 104 x 59 x 33 mm (4.09 x 2.32 x 1.3″) and weighs 217 g (0.48 lb / 7.65 oz) (including batteries). Olympus E-P5 has external dimensions of 122 x 69 x 37 mm (4.8 x 2.72 x 1.46″) and weighs 420 g (0.93 lb / 14.82 oz) (including batteries).
Below you can see the front-view size comparison of the Fujifilm F660EXR and the Olympus E-P5. Fujifilm F660EXR is clearly the smaller of the two cameras. Its body is 18mm narrower, 10mm shorter and 4mm thinner than Olympus E-P5. As you can tell, actually this is not a fair size comparison since Fujifilm F660EXR has a built-in lens but Olympus E-P5 doesn't. Once you put a lens on E-P5, its thickness will increase significantly.
Here is the back view size comparison of the Fujifilm F660EXR and Olympus E-P5.
Now lets look at the top view comparison of Fujifilm F660EXR and Olympus E-P5.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm F660EXR is significantly lighter (203g ) than the Olympus E-P5 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 E-P5, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Fujifilm FinePix F660EXR nor Olympus PEN E-P5 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 F660EXR and Olympus E-P5's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus E-P5 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Fujifilm F660EXR has a fixed type screen which provides less flexibility in shooting positions compared to E-P5.
