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 SX730 HS and Canon G7 X MIII side-by-side from the front, back and top in their relative dimensions. 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). Canon G7 X MIII has external dimensions of 105 x 61 x 41 mm (4.13 x 2.4 x 1.61″) and weighs 304 g (0.67 lb / 10.72 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX730 HS and the Canon G7 X MIII. Canon G7 X MIII is 5mm narrower and 3mm shorter than Canon SX730 HS but it is also 1mm thicker.
Here is the back view size comparison of the Canon SX730 HS and Canon G7 X MIII.
Now lets look at the top view comparison of Canon SX730 HS and Canon G7 X MIII.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX730 HS is 4g lighter than the Canon G7 X MIII but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Canon PowerShot SX730 HS nor Canon PowerShot G7 X Mark III provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.
