Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon ELPH 150 IS and Nikon Df side-by-side from the front, back and top in their relative dimensions. Canon ELPH 150 IS has external dimensions of 95 x 57 x 24 mm (3.74 x 2.24 x 0.94″) and weighs 142 g (0.31 lb / 5.01 oz) (including batteries). Nikon Df has external dimensions of 144 x 110 x 67 mm (5.67 x 4.33 x 2.64″) and weighs 760 g (1.68 lb / 26.81 oz) (including batteries).
Below you can see the front view size comparison of Canon ELPH 150 IS and Nikon Df. Canon ELPH 150 IS is clearly the smaller of the two cameras. Its body is 49mm narrower, 53mm shorter and 43mm thinner than Nikon Df. As you can tell, actually this is not a fair size comparison since Canon ELPH 150 IS has a built-in lens but Nikon Df doesn't. Once you put a lens on Df, its thickness will increase significantly.
Here is the back view size comparison of Canon ELPH 150 IS and Nikon Df.
Now lets look at the top view comparison of Canon ELPH 150 IS and Nikon Df.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 150 IS is significantly lighter (618g ) than the Nikon Df 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 Df, the total kit will weigh much higher.
Thanks to the weather sealed body of Df, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to ELPH 150 IS.
