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 Panasonic ZS70 and Nikon D7000 side-by-side from the front, back and top in their relative dimensions. Panasonic ZS70 has external dimensions of 112 x 67 x 41 mm (4.41 x 2.64 x 1.61″) and weighs 322 g (0.71 lb / 11.36 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Panasonic ZS70 and the Nikon D7000. Panasonic ZS70 is clearly the smaller of the two cameras. Its body is 20mm narrower, 38mm shorter and 36mm thinner than Nikon D7000. As you can tell, actually this is not a fair size comparison since Panasonic ZS70 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 Panasonic ZS70 and Nikon D7000.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS70 is significantly lighter (458g ) 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.
Weather Sealing
Thanks to the weather-sealed body of the D7000, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the ZS70.
LCD Screen Size and Features
Panasonic ZS70 and Nikon D7000's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic ZS70 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 ZS70.
