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 Pentax Q7 and Nikon P7700 side-by-side from the front, back and top in their relative dimensions. Pentax Q7 has external dimensions of 102 x 58 x 34 mm (4.02 x 2.28 x 1.34″) and weighs 200 g (0.44 lb / 7.05 oz) (including batteries). Nikon P7700 has external dimensions of 119 x 73 x 50 mm (4.69 x 2.87 x 1.97″) and weighs 392 g (0.86 lb / 13.83 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax Q7 and the Nikon P7700. Pentax Q7 is clearly the smaller of the two cameras. Its body is 17mm narrower, 15mm shorter and 16mm thinner than Nikon P7700. As you can tell, actually this is not a fair size comparison since Nikon P7700 has a built-in lens but Pentax Q7 doesn't. Once you put a lens on Q7, its thickness will increase significantly.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax Q7 is significantly lighter (192g ) than the Nikon P7700 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 Q7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Pentax Q7 nor Nikon Coolpix P7700 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Pentax Q7 and Nikon P7700's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon P7700 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. Pentax Q7's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P7700.
