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 SX70 HS and Panasonic GX8 side-by-side from the front, back and top in their relative dimensions. Canon SX70 HS has external dimensions of 127 x 91 x 117 mm (5 x 3.58 x 4.61″) and weighs 608 g (1.34 lb / 21.45 oz) (including batteries). Panasonic GX8 has external dimensions of 133 x 78 x 63 mm (5.24 x 3.07 x 2.48″) and weighs 487 g (1.07 lb / 17.18 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SX70 HS and the Panasonic GX8. Panasonic GX8 is 13mm shorter and 54mm thinner than Canon SX70 HS but it is also 6mm wider. As you can tell, actually this is not a fair size comparison since Canon SX70 HS has a built-in lens but Panasonic GX8 doesn't. Once you put a lens on GX8, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX70 HS and Panasonic GX8.
Now lets look at the top view comparison of Canon SX70 HS and Panasonic GX8.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic GX8 is significantly lighter (121g ) than the Canon SX70 HS 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 GX8, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the GX8, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the SX70 HS.
LCD Screen Size and Features
Canon SX70 HS and Panasonic GX8's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Fully Articulating screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. Fully articulating screens are also useful for taking Selfies and video.
