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 A900 and Panasonic S1H side-by-side from the front, back and top in their relative dimensions. Sony A900 has external dimensions of 156 x 117 x 82 mm (6.14 x 4.61 x 3.23″) and weighs 895 g (1.97 lb / 31.57 oz) (including batteries). Panasonic S1H has external dimensions of 151 x 114 x 110 mm (5.94 x 4.49 x 4.33″) and weighs 1052 g (2.32 lb / 37.11 oz) (including batteries).
Below you can see the front-view size comparison of the Sony A900 and the Panasonic S1H. Panasonic S1H is 5mm narrower and 3mm shorter than Sony A900 but it is also 28mm thicker.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A900 is significantly lighter (157g ) than the Panasonic S1H which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Sony A900 and Panasonic S1H have the same Full frame sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
Weather Sealing
Both the A900 and the S1H have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Panasonic S1H's 3.20" LCD screen is slightly larger than Sony A900's 3" screen.
Moreover, Panasonic S1H sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Sony A900 has a fixed type screen which provides almost no flexibility in shooting positions compared to S1H.
