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 GX8 and Sony RX10 IV side-by-side from the front, back and top in their relative dimensions. Panasonic GX8 has external dimensions of 133 x 78 x 63 mm (5.24 x 3.07 x 2.48″) and weighs 487 g (1.07 lb / 17.18 oz) (including batteries). Sony RX10 IV has external dimensions of 133 x 94 x 145 mm (5.24 x 3.7 x 5.71″) and weighs 1095 g (2.41 lb / 38.62 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic GX8 and the Sony RX10 IV. Panasonic GX8 has the same height with Sony RX10 IV. On the other hand, with a width of 78mm, it is 16 narrower and also with a thickness of 63mm, it is 82mm thinner than Sony RX10 IV. As you can tell, actually this is not a fair size comparison since Sony RX10 IV has a built-in lens but Panasonic GX8 doesn't. Once you put a lens on GX8, its thickness will increase significantly.
Here is the back view size comparison of the Panasonic GX8 and Sony RX10 IV.
Now lets look at the top view comparison of Panasonic GX8 and Sony RX10 IV.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic GX8 is significantly lighter (608g ) than the Sony RX10 IV 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 GX8, the total kit will weigh much higher.
Weather Sealing
Both the GX8 and the RX10 IV have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Panasonic GX8 and Sony RX10 IV's LCD screens have the same diagonal size of 3.00 inches.
Sony RX10 IV features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Panasonic GX8 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
