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 Sony A35 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). Sony A35 has external dimensions of 124 x 92 x 85 mm (4.88 x 3.62 x 3.35″) and weighs 415 g (0.91 lb / 14.64 oz) (including batteries).
Below you can see the front view size comparison of Nikon L120 and Sony A35. Nikon L120 is clearly the smaller of the two cameras. Its body is 14mm narrower, 15mm shorter and 7mm thinner than Sony A35. As you can tell, actually this is not a fair size comparison since Nikon L120 has a built-in lens but Sony A35 doesn't. Once you put a lens on A35, its thickness will increase significantly.
Here is the back view size comparison of Nikon L120 and Sony A35.
Now lets look at the top view comparison of Nikon L120 and Sony A35.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A35 is 16g lighter than the Nikon L120 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 A35, the total kit will weigh much higher.
Unfortunately neither Nikon Coolpix L120 nor Sony SLT-A35 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.
