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 Nikon P500 and Pentax K-01 side-by-side from the front, back and top in their relative dimensions. Nikon P500 has external dimensions of 116 x 84 x 10 mm (4.57 x 3.31 x 4.06″) and weighs 494 g (1.09 lb / 17.43 oz) (including batteries). Pentax K-01 has external dimensions of 122 x 79 x 58 mm (4.8 x 3.11 x 2.28″) and weighs 561 g (1.24 lb / 19.79 oz) (including batteries).
Below you can see the front view size comparison of Nikon P500 and Pentax K-01. Pentax K-01 is 5mm shorter and 45mm thinner than Nikon P500 but it is also 6mm wider. As you can tell, actually this is not a fair size comparison since Nikon P500 has a built-in lens but Pentax K-01 doesn't. Once you put a lens on K-01, 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.
Nikon P500 is 67g lighter than the Pentax K-01 but we don't think this will make a significant difference.
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 K-01, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Nikon Coolpix P500 nor Pentax K-01 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon P500 and Pentax K-01's LCD screens has the same diagonal size of 3".
On the other hand, Nikon P500 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 K-01 has a fixed type screen which provides less flexibility in shooting positions compared to P500.
