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 TG-820 iHS and Sony NEX-6 side-by-side from the front, back and top in their relative dimensions. Olympus TG-820 iHS has external dimensions of 101 x 65 x 26 mm (3.98 x 2.56 x 1.02″) and weighs 206 g (0.45 lb / 7.27 oz) (including batteries). Sony NEX-6 has external dimensions of 120 x 67 x 43 mm (4.72 x 2.64 x 1.69″) and weighs 345 g (0.76 lb / 12.17 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus TG-820 iHS and the Sony NEX-6. Olympus TG-820 iHS is clearly the smaller of the two cameras. Its body is 19mm narrower, 2mm shorter and 17mm thinner than Sony NEX-6. As you can tell, actually this is not a fair size comparison since Olympus TG-820 iHS has a built-in lens but Sony NEX-6 doesn't. Once you put a lens on NEX-6, its thickness will increase significantly.
Here is the back view size comparison of the Olympus TG-820 iHS and Sony NEX-6.
Now lets look at the top view comparison of Olympus TG-820 iHS and Sony NEX-6.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-820 iHS is significantly lighter (139g ) than the Sony NEX-6 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 NEX-6, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the TG-820 iHS, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the NEX-6.
LCD Screen Size and Features
Olympus TG-820 iHS and Sony NEX-6's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony NEX-6 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 Olympus TG-820 iHS has a fixed type screen which provides less flexibility in shooting positions compared to NEX-6.
