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 Ricoh GXR A16 24-85mm F3.5-5.5 and Panasonic GX8 side-by-side from the front, back and top in their relative dimensions. Ricoh GXR A16 24-85mm F3.5-5.5 has external dimensions of 114 x 75 x 93 mm (4.49 x 2.95 x 3.66″) and weighs 550 g (including batteries). 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).
Below you can see the front view size comparison of Ricoh GXR A16 24-85mm F3.5-5.5 and Panasonic GX8. Ricoh GXR A16 24-85mm F3.5-5.5 is 19mm narrower and 3mm shorter than Panasonic GX8 but it is also 30mm thicker. As you can tell, actually this is not a fair size comparison since Ricoh GXR A16 24-85mm F3.5-5.5 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 Ricoh GXR A16 24-85mm F3.5-5.5 and Panasonic GX8.
Now lets look at the top view comparison of Ricoh GXR A16 24-85mm F3.5-5.5 and Panasonic GX8.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic GX8 is 63g lighter than the Ricoh GXR A16 24-85mm F3.5-5.5 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.
Thanks to the weather sealed body of GX8, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to GXR A16 24-85mm F3.5-5.5.
