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 TX30 and Olympus E-PL6 side-by-side from the front, back and top in their relative dimensions. Sony TX30 has external dimensions of and weighs 141 g (including batteries). Olympus E-PL6 has external dimensions of 111 x 64 x 38 mm (4.37 x 2.52 x 1.5″) and weighs 325 g (0.72 lb / 11.46 oz) (including batteries).
Below you can see the front-view size comparison of the Sony TX30 and the Olympus E-PL6. Sony TX30 is clearly the smaller of the two cameras. Its body is 15mm narrower, 5mm shorter and 23mm thinner than Olympus E-PL6. As you can tell, actually this is not a fair size comparison since Sony TX30 has a built-in lens but Olympus E-PL6 doesn't. Once you put a lens on E-PL6, its thickness will increase significantly.
Here is the back view size comparison of the Sony TX30 and Olympus E-PL6.
Now lets look at the top view comparison of Sony TX30 and Olympus E-PL6.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony TX30 is significantly lighter (184g ) than the Olympus E-PL6 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-PL6, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the TX30 has a big advantage over the E-PL6 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony TX30's 3.30" LCD screen is slightly larger than Olympus E-PL6's 3" screen.
