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 SP-610UZ and Canon G16 side-by-side from the front, back and top in their relative dimensions. Olympus SP-610UZ has external dimensions of 107 x 73 x 73 mm (4.21 x 2.87 x 2.87″) and weighs 405 g (0.89 lb / 14.29 oz) (including batteries). Canon G16 has external dimensions of 109 x 76 x 40 mm (4.29 x 2.99 x 1.57″) and weighs 356 g (0.78 lb / 12.56 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SP-610UZ and the Canon G16. Olympus SP-610UZ is 2mm narrower and 3mm shorter than Canon G16 but it is also 33mm thicker.
Here is the back view size comparison of the Olympus SP-610UZ and Canon G16.
Now lets look at the top view comparison of Olympus SP-610UZ and Canon G16.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon G16 is 49g lighter than the Olympus SP-610UZ but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus SP-610UZ nor Canon PowerShot G16 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Olympus SP-610UZ and Canon G16's LCD screens have the same diagonal size of 3.00 inches.
