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 Nikon D4s and Panasonic FZ47 side-by-side from the front, back and top in their relative dimensions. Nikon D4s has external dimensions of 160 x 157 x 91 mm (6.3 x 6.18 x 3.58″) and weighs 1350 g (2.98 lb / 47.62 oz) (including batteries). Panasonic FZ47 has external dimensions of 120 x 80 x 92 mm (4.72 x 3.15 x 3.62″) and weighs 498 g (1.10 lb / 17.57 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon D4s and the Panasonic FZ47. Panasonic FZ47 is 40mm narrower and 77mm shorter than Nikon D4s but it is also 1mm thicker. As you can tell, actually this is not a fair size comparison since Panasonic FZ47 has a built-in lens but Nikon D4s doesn't. Once you put a lens on D4s, its thickness will increase significantly.
Here is the back view size comparison of the Nikon D4s and Panasonic FZ47.
Now lets look at the top view comparison of Nikon D4s and Panasonic FZ47.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FZ47 is significantly lighter (852g ) than the Nikon D4s 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 D4s, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the D4s has a big advantage over the FZ47 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon D4s's 3.20" LCD screen is slightly larger than Panasonic FZ47's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
