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 Pentax RZ10 and Nikon P7800 side-by-side from the front, back and top in their relative dimensions. Pentax RZ10 has external dimensions of 97 x 61 x 33 mm (3.82 x 2.4 x 1.3″) and weighs 178 g (0.39 lb / 6.28 oz) (including batteries). Nikon P7800 has external dimensions of 119 x 78 x 50 mm (4.69 x 3.07 x 1.97″) and weighs 399 g (0.88 lb / 14.07 oz) (including batteries).
Below you can see the front view size comparison of Pentax RZ10 and Nikon P7800. Pentax RZ10 is clearly the smaller of the two cameras. Its body is 22mm narrower, 17mm shorter and 17mm thinner than Nikon P7800.
Here is the back view size comparison of Pentax RZ10 and Nikon P7800.
Now lets look at the top view comparison of Pentax RZ10 and Nikon P7800.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Pentax RZ10 is significantly lighter (221g ) than the Nikon P7800 which may become a big advantage especially on long walking trips.
With its weather sealed body, we believe that RZ10 has a big advantage over P7800 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon P7800's 3" LCD screen is slightly larger than Pentax RZ10's 2.7" screen.
Moreover, Nikon P7800 sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Pentax RZ10 has a fixed type screen which provides almost no flexibility in shooting positions compared to P7800.
