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 Sony A7S and Samsung HZ25W side-by-side from the front, back and top in their relative dimensions. Sony A7S has external dimensions of 127 x 94 x 48 mm (5 x 3.7 x 1.89″) and weighs 489 g (1.08 lb / 17.25 oz) (including batteries). Samsung HZ25W has external dimensions of 116 x 83 x 92 mm (4.57 x 3.27 x 3.62″) and weighs 428 g (0.94 lb / 15.10 oz) (including batteries).
Below you can see the front view size comparison of Sony A7S and Samsung HZ25W. Samsung HZ25W is 11mm narrower and 11mm shorter than Sony A7S but it is also 44mm thicker. As you can tell, actually this is not a fair size comparison since Samsung HZ25W has a built-in lens but Sony A7S doesn't. Once you put a lens on A7S, 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.
Samsung HZ25W is 61g lighter than the Sony A7S 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 A7S, the total kit will weigh much higher.
Weather Sealing
With its weather sealed body, we believe that A7S has a big advantage over HZ25W which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A7S and Samsung HZ25W's LCD screens has the same diagonal size of 3.
On the other hand, Sony A7S 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 Samsung HZ25W has a fixed type screen which provides less flexibility in shooting positions compared to A7S.
Both Sony A7S and Samsung HZ25W have 12.0 MP resolution sensors but Sony A7S's sensor is Full frame (35.8 x 23.9 mm ) and Samsung HZ25W's sensor is 1/2.3" (6.08 x 4.56 mm ).
Since Sony A7S's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Samsung HZ25W.
Below you can see the A7S and HZ25W sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7S and Samsung HZ25W Cameras
As seen above, Sony A7S has a 30.9x Larger sensor area than Samsung HZ25W. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
