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 Nikon S810c 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). Nikon S810c has external dimensions of 113 x 64 x 28 mm (4.45 x 2.52 x 1.1″) and weighs 216 g (0.48 lb / 7.62 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic GX8 and the Nikon S810c. Nikon S810c is clearly the smaller of the two cameras. Its body is 20mm narrower, 14mm shorter and 35mm thinner than Panasonic GX8. As you can tell, actually this is not a fair size comparison since Nikon S810c 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 Nikon S810c.
Now lets look at the top view comparison of Panasonic GX8 and Nikon S810c.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S810c is significantly lighter (271g ) than the Panasonic GX8 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
With its weather-sealed body, we believe that the GX8 has a big advantage over the S810c which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon S810c's 3.70" LCD screen is slightly larger than Panasonic GX8's 3" screen.
On the other hand, Panasonic GX8 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Nikon S810c has a fixed type screen which provides almost no flexibility in shooting positions compared to GX8.
