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 Panasonic TS25 and Sony A580 side-by-side from the front, back and top in their relative dimensions. Panasonic TS25 has external dimensions of 104 x 58 x 20 mm (4.09 x 2.28 x 0.79″) and weighs 144 g (0.32 lb / 5.08 oz) (including batteries). Sony A580 has external dimensions of 137 x 104 x 84 mm (5.39 x 4.09 x 3.31″) and weighs 599 g (1.32 lb / 21.13 oz) (including batteries).
Below you can see the front view size comparison of Panasonic TS25 and Sony A580. Panasonic TS25 is clearly the smaller of the two cameras. Its body is 33mm narrower, 46mm shorter and 64mm thinner than Sony A580. As you can tell, actually this is not a fair size comparison since Panasonic TS25 has a built-in lens but Sony A580 doesn't. Once you put a lens on A580, its thickness will increase significantly.
Here is the back view size comparison of Panasonic TS25 and Sony A580.
Now lets look at the top view comparison of Panasonic TS25 and Sony A580.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Panasonic TS25 is significantly lighter (455g ) than the Sony A580 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 A580, the total kit will weigh much higher.
LCD Screen Size and Features
Sony A580's 3" LCD screen is slightly larger than Panasonic TS25's 2.7" screen.
In addition to the size advantage, Sony A580 LCD screen also has a Tilting feature
where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Panasonic TS25 has a fixed type screen which provides less flexibility in shooting positions compared to A580.
