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 A9 and Panasonic ZS200 side-by-side from the front, back and top in their relative dimensions. Sony A9 has external dimensions of 127 x 96 x 63 mm (5 x 3.78 x 2.48″) and weighs 673 g (1.48 lb / 23.74 oz) (including batteries). Panasonic ZS200 has external dimensions of 111 x 66 x 45 mm (4.37 x 2.6 x 1.77″) and weighs 340 g (0.75 lb / 11.99 oz) (including batteries).
Below you can see the front-view size comparison of the Sony A9 and the Panasonic ZS200. Panasonic ZS200 is clearly the smaller of the two cameras. Its body is 16mm narrower, 30mm shorter and 18mm thinner than Sony A9. As you can tell, actually this is not a fair size comparison since Panasonic ZS200 has a built-in lens but Sony A9 doesn't. Once you put a lens on A9, its thickness will increase significantly.
Here is the back view size comparison of the Sony A9 and Panasonic ZS200.
Now lets look at the top view comparison of Sony A9 and Panasonic ZS200.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS200 is significantly lighter (333g ) than the Sony A9 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 A9, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the A9 has a big advantage over the ZS200 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A9 and Panasonic ZS200's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony A9 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 Panasonic ZS200 has a fixed type screen which provides less flexibility in shooting positions compared to A9.
