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 Sony HX300 and Nikon P510 side-by-side from the front, back and top in their relative dimensions. Sony HX300 has external dimensions of 130 x 93 x 103 mm (5.1 x 3.67 x 4.06″) and weighs 623 g (including batteries). Nikon P510 has external dimensions of 120 x 83 x 102 mm (4.72 x 3.27 x 4.02″) and weighs 555 g (1.22 lb / 19.58 oz) (including batteries).
Below you can see the front-view size comparison of the Sony HX300 and the Nikon P510. Nikon P510 is clearly the smaller of the two cameras. Its body is 10mm narrower, 10mm shorter and 1mm thinner than Sony HX300.
Here is the back view size comparison of the Sony HX300 and Nikon P510.
Now lets look at the top view comparison of Sony HX300 and Nikon P510.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P510 is 68g lighter than the Sony HX300 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-HX300 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.
