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 D500 and Canon SX730 HS side-by-side from the front, back and top in their relative dimensions. Nikon D500 has external dimensions of 147 x 115 x 81 mm (5.79 x 4.53 x 3.19″) and weighs 860 g (1.90 lb / 30.34 oz) (including batteries). Canon SX730 HS has external dimensions of 110 x 64 x 40 mm (4.33 x 2.52 x 1.57″) and weighs 300 g (0.66 lb / 10.58 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon D500 and the Canon SX730 HS. Canon SX730 HS is clearly the smaller of the two cameras. Its body is 37mm narrower, 51mm shorter and 41mm thinner than Nikon D500. As you can tell, actually this is not a fair size comparison since Canon SX730 HS has a built-in lens but Nikon D500 doesn't. Once you put a lens on D500, its thickness will increase significantly.
Here is the back view size comparison of the Nikon D500 and Canon SX730 HS.
Now lets look at the top view comparison of Nikon D500 and Canon SX730 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX730 HS is significantly lighter (560g ) than the Nikon D500 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 D500, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the D500 has a big advantage over the SX730 HS which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Nikon D500's 3.20" LCD screen is slightly larger than Canon SX730 HS's 3 screen.
Both cameras feature
Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
