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 L840 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 L840 has external dimensions of 114 x 89 x 96 mm (4.49 x 3.5 x 3.78″) and weighs 538 g (1.19 lb / 18.98 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic GX8 and the Nikon L840. Panasonic GX8 is 11mm shorter and 33mm thinner than Nikon L840 but it is also 19mm wider. As you can tell, actually this is not a fair size comparison since Nikon L840 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 L840.
Now lets look at the top view comparison of Panasonic GX8 and Nikon L840.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic GX8 is 51g lighter than the Nikon L840 but we don't think this will make a significant difference.
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 L840 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Panasonic GX8 and Nikon L840's LCD screens have the same diagonal size of 3.00 inches.
Nikon L840 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.
