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 Canon 1D MII and Nikon P500 side-by-side from the front, back and top in their relative dimensions. Canon 1D MII has external dimensions of 156 x 158 x 80 mm (6.14 x 6.22 x 3.15″) and weighs 1565 g (3.45 lb / 55.20 oz) (including batteries). Nikon P500 has external dimensions of 116 x 84 x 10 mm (4.57 x 3.31 x 4.06″) and weighs 494 g (1.09 lb / 17.43 oz) (including batteries).
Below you can see the front-view size comparison of the Canon 1D MII and the Nikon P500. Nikon P500 is 40mm narrower and 74mm shorter than Canon 1D MII but it is also 23mm thicker. As you can tell, actually this is not a fair size comparison since Nikon P500 has a built-in lens but Canon 1D MII doesn't. Once you put a lens on 1D MII, its thickness will increase significantly.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P500 is significantly lighter (1071g ) than the Canon 1D MII which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on 1D MII, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the 1D MII has a big advantage over the P500 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon P500's 3.00" LCD screen is slightly larger than Canon 1D MII's 2 screen.
In addition to the size advantage, Nikon P500 LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Canon 1D MII has a fixed type screen which provides less flexibility in shooting positions compared to P500.
