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-870 and Panasonic G5 side-by-side from the front, back and top in their relative dimensions. Olympus TG-870 has external dimensions of 113 x 64 x 28 mm (4.45 x 2.52 x 1.1″) and weighs 221 g (0.49 lb / 7.80 oz) (including batteries). Panasonic G5 has external dimensions of 120 x 83 x 71 mm (4.72 x 3.27 x 2.8″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus TG-870 and the Panasonic G5. Olympus TG-870 is clearly the smaller of the two cameras. Its body is 7mm narrower, 19mm shorter and 43mm thinner than Panasonic G5. As you can tell, actually this is not a fair size comparison since Olympus TG-870 has a built-in lens but Panasonic G5 doesn't. Once you put a lens on G5, its thickness will increase significantly.
Here is the back view size comparison of the Olympus TG-870 and Panasonic G5.
Now lets look at the top view comparison of Olympus TG-870 and Panasonic G5.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-870 is significantly lighter (175g ) than the Panasonic G5 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 G5, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the TG-870, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the G5.
LCD Screen Size and Features
Olympus TG-870 and Panasonic G5's LCD screens have the same diagonal size of 3.00 inches.
Olympus TG-870 features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Panasonic G5 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
