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 Olympus 1 and Canon SX40 HS side-by-side from the front, back and top in their relative dimensions. Olympus 1 has external dimensions of 116 x 87 x 57 mm (4.57 x 3.43 x 2.24″) and weighs 402 g (0.89 lb / 14.18 oz) (including batteries). Canon SX40 HS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 600 g (1.32 lb / 21.16 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus 1 and the Canon SX40 HS. Olympus 1 is clearly the smaller of the two cameras. Its body is 7mm narrower, 5mm shorter and 51mm thinner than Canon SX40 HS.
Here is the back view size comparison of the Olympus 1 and Canon SX40 HS.
Now lets look at the top view comparison of Olympus 1 and Canon SX40 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus 1 is significantly lighter (198g ) than the Canon SX40 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Olympus Stylus 1 nor Canon PowerShot SX40 HS provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Olympus 1's 3.00" LCD screen is slightly larger than Canon SX40 HS's 2.7 screen.
