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 Sony NEX-5R 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). Sony NEX-5R has external dimensions of 111 x 59 x 39 mm (4.37 x 2.32 x 1.54″) and weighs 276 g (0.61 lb / 9.74 oz) (including batteries).
Below you can see the front view size comparison of Nikon S6100 and Sony NEX-5R. Nikon S6100 is clearly the smaller of the two cameras. Its body is 13mm narrower, 1mm shorter and 12mm thinner than Sony NEX-5R. As you can tell, actually this is not a fair size comparison since Nikon S6100 has a built-in lens but Sony NEX-5R doesn't. Once you put a lens on NEX-5R, 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 significantly lighter (101g ) than the Sony NEX-5R which may become a big advantage especially on long walking trips.
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 NEX-5R, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Nikon Coolpix S6100 nor Sony Alpha NEX-5R provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon S6100 and Sony NEX-5R's LCD screens has the same diagonal size of 3.00".
On the other hand, Sony NEX-5R features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over the head levels whereas the Nikon S6100 has a fixed type screen which provides less flexibility in shooting positions compared to NEX-5R.
