Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic FX48 and Olympus E-5 side-by-side from the front, back and top in their relative dimensions. Panasonic FX48 has external dimensions of 95 x 53 x 22 mm (3.74 x 2.09 x 0.87″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries). Olympus E-5 has external dimensions of 143 x 117 x 75 mm (5.63 x 4.61 x 2.95″) and weighs 800 g (1.76 lb / 28.22 oz) (including batteries).
Below you can see the front view size comparison of Panasonic FX48 and Olympus E-5. Panasonic FX48 is clearly the smaller of the two cameras. Its body is 48mm narrower, 64mm shorter and 53mm thinner than Olympus E-5. As you can tell, actually this is not a fair size comparison since Panasonic FX48 has a built-in lens but Olympus E-5 doesn't. Once you put a lens on E-5, its thickness will increase significantly.
Here is the back view size comparison of Panasonic FX48 and Olympus E-5.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic FX48 is significantly lighter (650g ) than the Olympus E-5 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-5, the total kit will weigh much higher.
Thanks to the weather sealed body of E-5, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to FX48.
LCD Screen Size and Features
Olympus E-5's 3" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
Moreover, Olympus E-5 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. On the other hand, Panasonic FX48 has a fixed type screen which provides almost no flexibility in shooting positions compared to E-5.
