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 7D MII 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 7D MII has external dimensions of 149 x 112 x 78 mm (5.87 x 4.41 x 3.07″) and weighs 910 g (2.01 lb / 32.10 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX730 HS and the Canon 7D MII. Canon SX730 HS is clearly the smaller of the two cameras. Its body is 39mm narrower, 48mm shorter and 38mm thinner than Canon 7D MII. As you can tell, actually this is not a fair size comparison since Canon SX730 HS has a built-in lens but Canon 7D MII doesn't. Once you put a lens on 7D MII, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX730 HS and Canon 7D MII.
Now lets look at the top view comparison of Canon SX730 HS and Canon 7D MII.
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 (610g ) than the Canon 7D 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 7D MII, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the 7D MII, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the SX730 HS.
LCD Screen Size and Features
Canon SX730 HS and Canon 7D MII'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 7D MII has a fixed type screen which provides less flexibility in shooting positions compared to SX730 HS.
