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 Panasonic S1H 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). Panasonic S1H has external dimensions of 151 x 114 x 110 mm (5.94 x 4.49 x 4.33″) and weighs 1052 g (2.32 lb / 37.11 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX720 HS and the Panasonic S1H. Canon SX720 HS is clearly the smaller of the two cameras. Its body is 41mm narrower, 50mm shorter and 74mm thinner than Panasonic S1H. As you can tell, actually this is not a fair size comparison since Canon SX720 HS has a built-in lens but Panasonic S1H doesn't. Once you put a lens on S1H, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX720 HS and Panasonic S1H.
Now lets look at the top view comparison of Canon SX720 HS and Panasonic S1H.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SX720 HS is significantly lighter (782g ) than the Panasonic S1H 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 S1H, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the S1H, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the SX720 HS.
LCD Screen Size and Features
Panasonic S1H's 3.20" LCD screen is slightly larger than Canon SX720 HS's 3 screen.
Moreover, Panasonic S1H sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Canon SX720 HS has a fixed type screen which provides almost no flexibility in shooting positions compared to S1H.
