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 L120 and Nikon 1 J1 side-by-side from the front, back and top in their relative dimensions. Nikon L120 has external dimensions of 110 x 77 x 78 mm (4.33 x 3.03 x 3.07″) and weighs 431 g (0.95 lb / 15.20 oz) (including batteries). Nikon 1 J1 has external dimensions of 106 x 61 x 30 mm (4.17 x 2.4 x 1.18″) and weighs 234 g (0.52 lb / 8.25 oz) (including batteries).
Below you can see the front view size comparison of Nikon L120 and Nikon 1 J1. Nikon 1 J1 is clearly the smaller of the two cameras. Its body is 4mm narrower, 16mm shorter and 48mm thinner than Nikon L120. As you can tell, actually this is not a fair size comparison since Nikon L120 has a built-in lens but Nikon 1 J1 doesn't. Once you put a lens on 1 J1, 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 1 J1 is significantly lighter (197g ) than the Nikon L120 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 1 J1, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Nikon Coolpix L120 nor Nikon 1 J1 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
