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 ELPH 190 IS and Sony A7c side-by-side from the front, back and top in their relative dimensions. Canon ELPH 190 IS has external dimensions of 95 x 57 x 24 mm (3.74 x 2.24 x 0.94″) and weighs 138 g (0.30 lb / 4.87 oz) (including batteries). Sony A7c has external dimensions of 124 x 71 x 60 mm (4.88 x 2.8 x 2.36″) and weighs 509 g (1.12 lb / 17.95 oz) (including batteries).
Below you can see the front-view size comparison of the Canon ELPH 190 IS and the Sony A7c. Canon ELPH 190 IS is clearly the smaller of the two cameras. Its body is 29mm narrower, 14mm shorter and 36mm thinner than Sony A7c. As you can tell, actually this is not a fair size comparison since Canon ELPH 190 IS has a built-in lens but Sony A7c doesn't. Once you put a lens on A7c, its thickness will increase significantly.
Here is the back view size comparison of the Canon ELPH 190 IS and Sony A7c.
Now lets look at the top view comparison of Canon ELPH 190 IS and Sony A7c.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 190 IS is significantly lighter (371g ) than the Sony A7c 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 A7c, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the A7c, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the 190 IS.
