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 S6100 and Pentax Q7 side-by-side from the front, back and top in their relative dimensions. Nikon S6100 has external dimensions of 98 x 58 x 27 mm (3.86 x 2.28 x 1.06″) and weighs 175 g (0.39 lb / 6.17 oz) (including batteries). Pentax Q7 has external dimensions of 102 x 58 x 34 mm (4.02 x 2.28 x 1.34″) and weighs 200 g (0.44 lb / 7.05 oz) (including batteries).
Below you can see the front view size comparison of Nikon S6100 and Pentax Q7. Nikon S6100 is 4mm narrower and 7mm thinner than Nikon S6100 but they have the same height of 58mm. As you can tell, actually this is not a fair size comparison since Nikon S6100 has a built-in lens but Pentax Q7 doesn't. Once you put a lens on Q7, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon S6100 is 25g lighter than the Pentax Q7 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 Q7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Nikon Coolpix S6100 nor Pentax Q7 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
