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 FE-5020 and Olympus E-PL1s side-by-side from the front, back and top in their relative dimensions. Olympus FE-5020 has external dimensions of 93 x 56 x 25 mm (3.66 x 2.2 x 0.98″) and weighs 137 g (0.30 lb / 4.83 oz) (including batteries). Olympus E-PL1s has external dimensions of 115 x 72 x 42 mm (4.53 x 2.83 x 1.65″) and weighs 334 g (0.74 lb / 11.78 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus FE-5020 and the Olympus E-PL1s. Olympus FE-5020 is clearly the smaller of the two cameras. Its body is 22mm narrower, 16mm shorter and 17mm thinner than Olympus E-PL1s. As you can tell, actually this is not a fair size comparison since Olympus FE-5020 has a built-in lens but Olympus E-PL1s doesn't. Once you put a lens on E-PL1s, its thickness will increase significantly.
Here is the back view size comparison of the Olympus FE-5020 and Olympus E-PL1s.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus FE-5020 is significantly lighter (197g ) than the Olympus E-PL1s 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-PL1s, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the FE-5020 has a big advantage over the E-PL1s which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Olympus FE-5020 and Olympus E-PL1s's LCD screens have the same diagonal size of 2.70 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
