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 FZ1000 II and Sony A6400 side-by-side from the front, back and top in their relative dimensions. Panasonic FZ1000 II has external dimensions of 136 x 97 x 132 mm (5.35 x 3.82 x 5.2″) and weighs 808 g (1.78 lb / 28.50 oz) (including batteries). Sony A6400 has external dimensions of 120 x 67 x 50 mm (4.72 x 2.64 x 2.36″) and weighs 403 g (0.89 lb / 14.22 oz) (including batteries).
Below you can see the front view size comparison of Panasonic FZ1000 II and Sony A6400. Sony A6400 is clearly the smaller of the two cameras. Its body is 16mm narrower, 30mm shorter and 82mm thinner than Panasonic FZ1000 II. As you can tell, actually this is not a fair size comparison since Panasonic FZ1000 II has a built-in lens but Sony A6400 doesn't. Once you put a lens on A6400, its thickness will increase significantly.
Here is the back view size comparison of Panasonic FZ1000 II and Sony A6400.
Now lets look at the top view comparison of Panasonic FZ1000 II and Sony A6400.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony A6400 is significantly lighter (405g ) than the Panasonic FZ1000 II 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 A6400, the total kit will weigh much higher.
Thanks to the weather sealed body of A6400, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to FZ1000 II.
