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 Nikon D3S and Samsung WB30F side-by-side from the front, back and top in their relative dimensions. Nikon D3S has external dimensions of 160 x 157 x 88 mm (6.3 x 6.18 x 3.46″) and weighs 1240 g (2.73 lb / 43.74 oz) (including batteries). Samsung WB30F has external dimensions of 98 x 58 x 17 mm (3.86 x 2.28 x 0.67″) and weighs 128 g (0.28 lb / 4.52 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon D3S and the Samsung WB30F. Samsung WB30F is clearly the smaller of the two cameras. Its body is 62mm narrower, 99mm shorter and 71mm thinner than Nikon D3S. As you can tell, actually this is not a fair size comparison since Samsung WB30F has a built-in lens but Nikon D3S doesn't. Once you put a lens on D3S, its thickness will increase significantly.
Now lets look at the top view comparison of Nikon D3S and Samsung WB30F.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung WB30F is significantly lighter (1112g ) than the Nikon D3S 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 D3S, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the D3S has a big advantage over the WB30F which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon D3S and Samsung WB30F's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
