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 Sony TX20 and Olympus E-P5 side-by-side from the front, back and top in their relative dimensions. Sony TX20 has external dimensions of 96 x 56 x 18 mm (3.78 x 2.2 x 0.71″) and weighs 133 g (0.29 lb / 4.69 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 Sony TX20 and the Olympus E-P5. Sony TX20 is clearly the smaller of the two cameras. Its body is 26mm narrower, 13mm shorter and 19mm thinner than Olympus E-P5. As you can tell, actually this is not a fair size comparison since Sony TX20 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 Sony TX20 and Olympus E-P5.
Now lets look at the top view comparison of Sony TX20 and Olympus E-P5.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX20 is significantly lighter (287g ) 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
With its weather-sealed body, we believe that the TX20 has a big advantage over the E-P5 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony TX20 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 Sony TX20 has a fixed type screen which provides less flexibility in shooting positions compared to E-P5.
