Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon P500 and Panasonic GH4 side-by-side from the front, back and top in their relative dimensions. Nikon P500 has external dimensions of 116 x 84 x 10 mm (4.57 x 3.31 x 4.06″) and weighs 494 g (1.09 lb / 17.43 oz) (including batteries). Panasonic GH4 has external dimensions of 133 x 93 x 84 mm (5.24 x 3.66 x 3.31″) and weighs 560 g (1.23 lb / 19.75 oz) (including batteries).
Below you can see the front view size comparison of Nikon P500 and Panasonic GH4. Nikon P500 is 17mm narrower and 9mm shorter than Panasonic GH4 but it is also 19mm thicker. As you can tell, actually this is not a fair size comparison since Nikon P500 has a built-in lens but Panasonic GH4 doesn't. Once you put a lens on GH4, its thickness will increase significantly.
Here is the back view size comparison of Nikon P500 and Panasonic GH4.
Now lets look at the top view comparison of Nikon P500 and Panasonic GH4.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon P500 is 66g lighter than the Panasonic GH4 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 GH4, the total kit will weigh much higher.
Thanks to the weather sealed body of GH4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to P500.
