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 GX85 and Olympus TG-810 side-by-side from the front, back and top in their relative dimensions. Panasonic GX85 has external dimensions of 122 x 71 x 44 mm (4.8 x 2.8 x 1.73��) and weighs 426 g (0.94 lb / 15.03 oz) (including batteries). Olympus TG-810 has external dimensions of 100 x 65 x 26 mm (3.94 x 2.56 x 1.02″) and weighs 215 g (0.47 lb / 7.58 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic GX85 and the Olympus TG-810. Olympus TG-810 is clearly the smaller of the two cameras. Its body is 22mm narrower, 6mm shorter and 18mm thinner than Panasonic GX85. As you can tell, actually this is not a fair size comparison since Olympus TG-810 has a built-in lens but Panasonic GX85 doesn't. Once you put a lens on GX85, its thickness will increase significantly.
Here is the back view size comparison of the Panasonic GX85 and Olympus TG-810.
Now lets look at the top view comparison of Panasonic GX85 and Olympus TG-810.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-810 is significantly lighter (211g ) than the Panasonic GX85 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 GX85, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the TG-810, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the GX85.
LCD Screen Size and Features
Panasonic GX85 and Olympus TG-810's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic GX85 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-810 has a fixed type screen which provides less flexibility in shooting positions compared to GX85.
