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 Q and Nikon P100 side-by-side from the front, back and top in their relative dimensions. Pentax Q has external dimensions of 98 x 57 x 31 mm (3.86 x 2.24 x 1.22″) and weighs 180 g (0.40 lb / 6.35 oz) (including batteries). Nikon P100 has external dimensions of 114 x 83 x 99 mm (4.49 x 3.27 x 3.9″) and weighs 481 g (1.06 lb / 16.97 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax Q and the Nikon P100. Pentax Q is clearly the smaller of the two cameras. Its body is 16mm narrower, 26mm shorter and 68mm thinner than Nikon P100. As you can tell, actually this is not a fair size comparison since Nikon P100 has a built-in lens but Pentax Q doesn't. Once you put a lens on Q, 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 Q is significantly lighter (301g ) than the Nikon P100 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 Q, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Pentax Q nor Nikon Coolpix P100 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 Q and Nikon P100's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon P100 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 Pentax Q has a fixed type screen which provides less flexibility in shooting positions compared to P100.
