Panasonic SZ5 has external dimensions of 104 x 58 x 21 mm (4.09 x 2.28 x 0.83″) and weighs 136 g (0.30 lb / 4.80 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic SZ5 is significantly lighter (419g ) than the Nikon P510 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-SZ5 nor Nikon Coolpix P510 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 SZ5 and Nikon P510's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon P510 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 Panasonic SZ5 has a fixed type screen which provides less flexibility in shooting positions compared to P510.
