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 Nikon P300 and Panasonic 3D1 side-by-side from the front, back and top in their relative dimensions. Nikon P300 has external dimensions of 103 x 58 x 32 mm (4.06 x 2.28 x 1.26″) and weighs 189 g (0.42 lb / 6.67 oz) (including batteries). Panasonic 3D1 has external dimensions of 108 x 58 x 24 mm (4.25 x 2.28 x 0.94″) and weighs 193 g (0.43 lb / 6.81 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon P300 and the Panasonic 3D1.
Here is the back view size comparison of the Nikon P300 and Panasonic 3D1.
Now lets look at the top view comparison of Nikon P300 and Panasonic 3D1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P300 is 4g lighter than the Panasonic 3D1 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix P300 nor Panasonic Lumix DMC-3D1 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
Panasonic 3D1's 3.50" LCD screen is slightly larger than Nikon P300's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
