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 D300 and Nikon D300S side-by-side from the front, back and top in their relative dimensions. Nikon D300 has external dimensions of 147 x 114 x 74 mm (5.79 x 4.49 x 2.91″) and weighs 925 g (2.04 lb / 32.63 oz) (including batteries). Nikon D300S has external dimensions of 147 x 114 x 74 mm (5.79 x 4.49 x 2.91″) and weighs 938 g (2.07 lb / 33.09 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon D300 and the Nikon D300S. In this case, we can see that Nikon D300 and Nikon D300S have the exact same height, width and thickness.
Here is the back view size comparison of the Nikon D300 and Nikon D300S.
Now lets look at the top view comparison of Nikon D300 and Nikon D300S.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon D300 is 13g lighter than the Nikon D300S but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Nikon D300 and Nikon D300S have the same Nikon F lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Both the D300 and the D300S have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Nikon D300 and Nikon D300S's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
