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 340 HS and Olympus 5010 side-by-side from the front, back and top in their relative dimensions. Canon ELPH 340 HS has external dimensions of 100 x 58 x 22 mm (3.93 x 2.27 x 0.88″) and weighs 147 g (0.32 lb / 5.19 oz) (including batteries). Olympus 5010 has external dimensions of 95 x 56 x 20 mm (3.74 x 2.2 x 0.79″) and weighs 126 g (0.28 lb / 4.44 oz) (including batteries).
Below you can see the front-view size comparison of the Canon ELPH 340 HS and the Olympus 5010. Olympus 5010 is clearly the smaller of the two cameras. Its body is 5mm narrower, 2mm shorter and 2mm thinner than Canon ELPH 340 HS.
Here is the back view size comparison of the Canon ELPH 340 HS and Olympus 5010.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus 5010 is significantly lighter (21g ) than the Canon ELPH 340 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 340 HS (IXUS 265 HS) nor Olympus Stylus 5010 (mju 5010) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon ELPH 340 HS's 3.00" LCD screen is slightly larger than Olympus 5010's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
