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 WX220 and Sony NEX-C3 side-by-side from the front, back and top in their relative dimensions. Sony WX220 has external dimensions of 92 x 52 x 22 mm (3.62 x 2.05 x 0.87″) and weighs 121 g (0.27 lb / 4.27 oz) (including batteries). Sony NEX-C3 has external dimensions of 110 x 60 x 33 mm (4.33 x 2.36 x 1.3″) and weighs 225 g (0.50 lb / 7.94 oz) (including batteries).
Below you can see the front-view size comparison of the Sony WX220 and the Sony NEX-C3. Sony WX220 is clearly the smaller of the two cameras. Its body is 18mm narrower, 8mm shorter and 11mm thinner than Sony NEX-C3. As you can tell, actually this is not a fair size comparison since Sony WX220 has a built-in lens but Sony NEX-C3 doesn't. Once you put a lens on NEX-C3, its thickness will increase significantly.
Here is the back view size comparison of the Sony WX220 and Sony NEX-C3.
Now lets look at the top view comparison of Sony WX220 and Sony NEX-C3.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony WX220 is significantly lighter (104g ) than the Sony NEX-C3 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-C3, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-WX220 nor Sony Alpha NEX-C3 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 WX220 and Sony NEX-C3's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony NEX-C3 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 Sony WX220 has a fixed type screen which provides less flexibility in shooting positions compared to NEX-C3.
