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 D4 and Fujifilm S9400W side-by-side from the front, back and top in their relative dimensions. Nikon D4 has external dimensions of 160 x 157 x 91 mm (6.3 x 6.18 x 3.58″) and weighs 1340 g (2.95 lb / 47.27 oz) (including batteries). Fujifilm S9400W has external dimensions of 123 x 87 x 116 mm (4.84 x 3.43 x 4.57″) and weighs 670 g (1.48 lb / 23.63 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon D4 and the Fujifilm S9400W. Fujifilm S9400W is 37mm narrower and 70mm shorter than Nikon D4 but it is also 25mm thicker. As you can tell, actually this is not a fair size comparison since Fujifilm S9400W has a built-in lens but Nikon D4 doesn't. Once you put a lens on D4, its thickness will increase significantly.
Here is the back view size comparison of the Nikon D4 and Fujifilm S9400W.
Now lets look at the top view comparison of Nikon D4 and Fujifilm S9400W.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm S9400W is significantly lighter (670g ) than the Nikon D4 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 D4, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the D4 has a big advantage over the S9400W which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon D4's 3.20" LCD screen is slightly larger than Fujifilm S9400W's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
