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 Sony RX10 IV and Canon 70D side-by-side from the front, back and top in their relative dimensions. Sony RX10 IV has external dimensions of 133 x 94 x 145 mm (5.24 x 3.7 x 5.71″) and weighs 1095 g (2.41 lb / 38.62 oz) (including batteries). Canon 70D has external dimensions of 139 x 104 x 79 mm (5.47 x 4.11 x 3.09″) and weighs 755 g (1.66 lb / 26.63 oz) (including batteries).
Below you can see the front-view size comparison of the Sony RX10 IV and the Canon 70D. Sony RX10 IV is 6mm narrower and 10mm shorter than Canon 70D but it is also 66mm thicker. As you can tell, actually this is not a fair size comparison since Sony RX10 IV has a built-in lens but Canon 70D doesn't. Once you put a lens on 70D, its thickness will increase significantly.
Here is the back view size comparison of the Sony RX10 IV and Canon 70D.
Now lets look at the top view comparison of Sony RX10 IV and Canon 70D.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon 70D is significantly lighter (340g ) than the Sony RX10 IV 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 70D, the total kit will weigh much higher.
Weather Sealing
Both the RX10 IV and the 70D have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Sony RX10 IV and Canon 70D's LCD screens have the same diagonal size of 3.00 inches.
Sony RX10 IV features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Canon 70D sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
