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 P300 and Panasonic G5 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 G5 has external dimensions of 120 x 83 x 71 mm (4.72 x 3.27 x 2.8″) and weighs 396 g (0.87 lb / 13.97 oz) (including batteries).
Below you can see the front view size comparison of Nikon P300 and Panasonic G5. Nikon P300 is clearly the smaller of the two cameras. Its body is 17mm narrower, 25mm shorter and 39mm thinner than Panasonic G5. As you can tell, actually this is not a fair size comparison since Nikon P300 has a built-in lens but Panasonic G5 doesn't. Once you put a lens on G5, 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 P300 is significantly lighter (207g ) than the Panasonic G5 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 G5, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Nikon Coolpix P300 nor Panasonic Lumix DMC-G5 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 P300 and Panasonic G5's LCD screens has the same diagonal size of 3".
On the other hand, Panasonic G5 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. Nikon P300's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to G5.
