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 SX720 HS and Canon SX730 HS side-by-side from the front, back and top in their relative dimensions. Canon SX720 HS has external dimensions of 110 x 64 x 36 mm (4.33 x 2.52 x 1.42″) and weighs 270 g (0.60 lb / 9.52 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 Canon SX720 HS and the Canon SX730 HS. Canon SX720 HS has the same height and width with Canon SX730 HS. On the other hand, with a thickness of 36mm, it is 4mm thinner.
Here is the back view size comparison of the Canon SX720 HS and Canon SX730 HS.
Now lets look at the top view comparison of Canon SX720 HS 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 SX720 HS is 30g lighter than the Canon SX730 HS but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot SX720 HS nor Canon PowerShot SX730 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Canon SX720 HS and Canon SX730 HS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon SX730 HS features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon SX720 HS has a fixed type screen which provides less flexibility in shooting positions compared to SX730 HS.
