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 Kodak Astro AZ651 and Nikon P520 side-by-side from the front, back and top in their relative dimensions. Kodak Astro AZ651 has external dimensions of 125 x 114 x 89 mm and weighs 567 g (including batteries). Nikon P520 has external dimensions of 125 x 84 x 102 mm (4.92 x 3.31 x 4.02″) and weighs 550 g (1.21 lb / 19.40 oz) (including batteries).
Below you can see the front-view size comparison of the Kodak Astro AZ651 and the Nikon P520. Kodak Astro AZ651 is clearly the smaller of the two cameras. Its body is 125mm narrower, 84mm shorter and 102mm thinner than Nikon P520.
Now lets look at the top view comparison of Kodak Astro AZ651 and Nikon P520.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P520 is 17g lighter than the Kodak Astro AZ651 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Kodak Pixpro Astro Zoom AZ651 nor Nikon Coolpix P520 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
