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 P7800 and Panasonic ZS45 side-by-side from the front, back and top in their relative dimensions. Nikon P7800 has external dimensions of 119 x 78 x 50 mm (4.69 x 3.07 x 1.97″) and weighs 399 g (0.88 lb / 14.07 oz) (including batteries).

Now lets look at the top view comparison of Nikon P7800 and Panasonic ZS45.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic ZS45 is significantly lighter (150g ) than the Nikon P7800 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix P7800 nor Panasonic Lumix DMC-ZS45 (Lumix DMC-TZ57) 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
Nikon P7800 and Panasonic ZS45's LCD screens have the same diagonal size of 3.00 inches.
Panasonic ZS45 features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Nikon P7800 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
