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 Panasonic G100 and Olympus TG-850 iHS side-by-side from the front, back and top in their relative dimensions. Panasonic G100 has external dimensions of 116 x 83 x 54 mm (4.57 x 3.27 x 2.13″) and weighs 352 g (0.78 lb / 12.42 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Panasonic G100 and the Olympus TG-850 iHS. Olympus TG-850 iHS is clearly the smaller of the two cameras. Its body is 6mm narrower, 19mm shorter and 26mm thinner than Panasonic G100. As you can tell, actually this is not a fair size comparison since Olympus TG-850 iHS has a built-in lens but Panasonic G100 doesn't. Once you put a lens on G100, its thickness will increase significantly.
Here is the back view size comparison of the Panasonic G100 and Olympus TG-850 iHS.
Now lets look at the top view comparison of Panasonic G100 and Olympus TG-850 iHS.
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 (134g ) than the Panasonic G100 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 G100, 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 G100.
LCD Screen Size and Features
Panasonic G100 and Olympus TG-850 iHS'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 G100 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
