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 Panasonic FZ80 and Nikon P600 side-by-side from the front, back and top in their relative dimensions. Panasonic FZ80 has external dimensions of 130 x 94 x 119 mm (5.12 x 3.7 x 4.69″) and weighs 616 g (1.36 lb / 21.73 oz) (including batteries). Nikon P600 has external dimensions of 125 x 85 x 107 mm (4.92 x 3.35 x 4.21″) and weighs 565 g (1.25 lb / 19.93 oz) (including batteries).
Below you can see the front view size comparison of Panasonic FZ80 and Nikon P600. Nikon P600 is clearly the smaller of the two cameras. Its body is 5mm narrower, 9mm shorter and 12mm thinner than Panasonic FZ80.
Here is the back view size comparison of Panasonic FZ80 and Nikon P600.
Now lets look at the top view comparison of Panasonic FZ80 and Nikon P600.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon P600 is 51g lighter than the Panasonic FZ80 but we don't think this will make a significant difference.
Unfortunately neither Panasonic Lumix DMC-FZ80 (Lumix DMC-FZ82) nor Nikon Coolpix P600 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Bridge Cameras with Weather Sealing
LCD Screen Size and Features
Panasonic FZ80 and Nikon P600's LCD screens has the same diagonal size of 3".
On the other hand, Nikon P600 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. Panasonic FZ80's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to P600.
