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 WG-1 GPS and Nikon P7800 side-by-side from the front, back and top in their relative dimensions. Pentax WG-1 GPS has external dimensions of 116 x 59 x 29 mm (4.55 x 2.3 x 1.12″) and weighs 167 g (0.37 lb / 5.89 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 WG-1 GPS and Nikon P7800. Pentax WG-1 GPS is clearly the smaller of the two cameras. Its body is 3mm narrower, 19mm shorter and 21mm thinner than Nikon P7800.
Here is the back view size comparison of Pentax WG-1 GPS and Nikon P7800.
Now lets look at the top view comparison of Pentax WG-1 GPS and Nikon P7800.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Pentax WG-1 GPS is significantly lighter (232g ) than the Nikon P7800 which may become a big advantage especially on long walking trips.
LCD Screen Size and Features
Nikon P7800's 3" LCD screen is slightly larger than Pentax WG-1 GPS'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 WG-1 GPS has a fixed type screen which provides almost no flexibility in shooting positions compared to P7800.
