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-ZR10 and Nikon 1 S1 side-by-side from the front, back and top in their relative dimensions. Casio EX-ZR10 has external dimensions of 102 x 69 x 27 mm (4.02 x 2.72 x 1.06″) and weighs 176 g (0.39 lb / 6.21 oz) (including batteries). Nikon 1 S1 has external dimensions of 102 x 61 x 30 mm (4.02 x 2.4 x 1.18″) and weighs 197 g (0.43 lb / 6.95 oz) (including batteries).
Below you can see the front-view size comparison of the Casio EX-ZR10 and the Nikon 1 S1. As you can tell, actually this is not a fair size comparison since Casio EX-ZR10 has a built-in lens but Nikon 1 S1 doesn't. Once you put a lens on 1 S1, its thickness will increase significantly.
Here is the back view size comparison of the Casio EX-ZR10 and Nikon 1 S1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Casio EX-ZR10 is 21g lighter than the Nikon 1 S1 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 1 S1, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Casio Exilim EX-ZR10 nor Nikon 1 S1 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
