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 Ricoh PX and Nikon P7800 side-by-side from the front, back and top in their relative dimensions. Ricoh PX has external dimensions of 100 x 55 x 21 mm (3.94 x 2.17 x 0.83″) and weighs 156 g (0.34 lb / 5.50 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 the Ricoh PX and the Nikon P7800. Ricoh PX is clearly the smaller of the two cameras. Its body is 19mm narrower, 23mm shorter and 29mm thinner than Nikon P7800.
Here is the back view size comparison of the Ricoh PX and Nikon P7800.
Now lets look at the top view comparison of Ricoh PX and Nikon P7800.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Ricoh PX is significantly lighter (243g ) than the Nikon P7800 which may become a big advantage especially on long walking trips.
Weather Sealing
With its weather-sealed body, we believe that the PX has a big advantage over the P7800 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon P7800's 3.00" LCD screen is slightly larger than Ricoh PX'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, Ricoh PX has a fixed type screen which provides almost no flexibility in shooting positions compared to P7800.
