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 Casio EX-10 and Panasonic GX7 side-by-side from the front, back and top in their relative dimensions. Casio EX-10 has external dimensions of 120 x 68 x 49 mm (4.72 x 2.67 x 1.91″) and weighs 384 g (0.85 lb / 13.55 oz) (including batteries). Panasonic GX7 has external dimensions of 123 x 71 x 55 mm (4.83 x 2.78 x 2.15″) and weighs 402 g (0.89 lb / 14.18 oz) (including batteries).
Below you can see the front-view size comparison of the Casio EX-10 and the Panasonic GX7. Casio EX-10 is clearly the smaller of the two cameras. Its body is 3mm narrower, 3mm shorter and 6mm thinner than Panasonic GX7. As you can tell, actually this is not a fair size comparison since Casio EX-10 has a built-in lens but Panasonic GX7 doesn't. Once you put a lens on GX7, its thickness will increase significantly.
Here is the back view size comparison of the Casio EX-10 and Panasonic GX7.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Casio EX-10 is 18g lighter than the Panasonic GX7 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 GX7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Casio Exilim EX-10 nor Panasonic Lumix DMC-GX7 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
