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-850 iHS and Panasonic G3 side-by-side from the front, back and top in their relative dimensions. Olympus TG-850 iHS has external dimensions of 110 x 64 x 28 mm (4.33 x 2.52 x 1.09″) and weighs 218 g (0.48 lb / 7.69 oz) (including batteries). Panasonic G3 has external dimensions of 115 x 84 x 47 mm (4.53 x 3.31 x 1.85″) and weighs 336 g (0.74 lb / 11.85 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus TG-850 iHS and the Panasonic G3. Olympus TG-850 iHS is clearly the smaller of the two cameras. Its body is 5mm narrower, 20mm shorter and 19mm thinner than Panasonic G3. As you can tell, actually this is not a fair size comparison since Olympus TG-850 iHS has a built-in lens but Panasonic G3 doesn't. Once you put a lens on G3, its thickness will increase significantly.
Here is the back view size comparison of the Olympus TG-850 iHS and Panasonic G3.
Now lets look at the top view comparison of Olympus TG-850 iHS and Panasonic G3.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-850 iHS is significantly lighter (118g ) than the Panasonic G3 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 G3, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the TG-850 iHS, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the G3.
LCD Screen Size and Features
Olympus TG-850 iHS and Panasonic G3's LCD screens have the same diagonal size of 3.00 inches.
Olympus TG-850 iHS features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Panasonic G3 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
