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 A580 and Fujifilm S1 side-by-side from the front, back and top in their relative dimensions. 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). Fujifilm S1 has external dimensions of 133 x 91 x 110 mm (5.24 x 3.58 x 4.33″) and weighs 680 g (1.50 lb / 23.99 oz) (including batteries).
Below you can see the front-view size comparison of the Sony A580 and the Fujifilm S1. Fujifilm S1 is 4mm narrower and 13mm shorter than Sony A580 but it is also 26mm thicker. As you can tell, actually this is not a fair size comparison since Fujifilm S1 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 the Sony A580 and Fujifilm S1.
Now lets look at the top view comparison of Sony A580 and Fujifilm S1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A580 is 81g lighter than the Fujifilm S1 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 A580, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the S1, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the A580.
LCD Screen Size and Features
Sony A580 and Fujifilm S1's LCD screens have the same diagonal size of 3.00 inches.
Sony A580 features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Fujifilm S1 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
