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 Nikon D7000 and Sony HX400V side-by-side from the front, back and top in their relative dimensions. Nikon D7000 has external dimensions of 132 x 105 x 77 mm (5.2 x 4.13 x 3.03″) and weighs 780 g (1.72 lb / 27.51 oz) (including batteries). Sony HX400V has external dimensions of 130 x 93 x 103 mm (5.1 x 3.67 x 4.06″) and weighs 660 g (1.46 lb / 23.28 oz) (including batteries).
Below you can see the front view size comparison of Nikon D7000 and Sony HX400V. Sony HX400V is 2mm narrower and 12mm shorter than Nikon D7000 but it is also 26mm thicker. As you can tell, actually this is not a fair size comparison since Sony HX400V has a built-in lens but Nikon D7000 doesn't. Once you put a lens on D7000, its thickness will increase significantly.
Now lets look at the top view comparison of Nikon D7000 and Sony HX400V.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony HX400V is significantly lighter (120g ) than the Nikon D7000 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 D7000, the total kit will weigh much higher.
With its weather sealed body, we believe that D7000 has a big advantage over HX400V which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon D7000 and Sony HX400V's LCD screens has the same diagonal size of 3".
On the other hand, Sony HX400V 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 Nikon D7000 has a fixed type screen which provides less flexibility in shooting positions compared to HX400V.
