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 Canon 1D MIV 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). Canon 1D MIV has external dimensions of 156 x 157 x 80 mm (6.14 x 6.18 x 3.15″) and weighs 1230 g (2.71 lb / 43.39 oz) (including batteries).
Below you can see the front view size comparison of Canon ELPH 150 IS and Canon 1D MIV. Canon ELPH 150 IS is clearly the smaller of the two cameras. Its body is 61mm narrower, 100mm shorter and 56mm thinner than Canon 1D MIV. As you can tell, actually this is not a fair size comparison since Canon ELPH 150 IS has a built-in lens but Canon 1D MIV doesn't. Once you put a lens on 1D MIV, its thickness will increase significantly.
Here is the back view size comparison of Canon ELPH 150 IS and Canon 1D MIV.
Now lets look at the top view comparison of Canon ELPH 150 IS and Canon 1D MIV.
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 (1088g ) than the Canon 1D MIV 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 1D MIV, the total kit will weigh much higher.
Thanks to the weather sealed body of 1D MIV, 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.
LCD Screen Size and Features
Canon 1D MIV's 3.00" LCD screen is slightly larger than Canon ELPH 150 IS's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
