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 Sony A6100 and Sony NEX-7 side-by-side from the front, back and top in their relative dimensions. Sony A6100 has external dimensions of 120 x 67 x 59 mm (4.72 x 2.64 x 2.32″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries). Sony NEX-7 has external dimensions of 120 x 67 x 43 mm (4.72 x 2.64 x 1.69″) and weighs 400 g (0.88 lb / 14.11 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A6100 is 4g lighter than the Sony NEX-7 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Sony A6100 and Sony NEX-7 have the same Sony E lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Sony Alpha a6100 nor Sony Alpha NEX-7 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Sony A6100 and Sony NEX-7's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
