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 SD4500 IS and Panasonic TS3 side-by-side from the front, back and top in their relative dimensions. Canon SD4500 IS has external dimensions of 101 x 59 x 22 mm (3.98 x 2.32 x 0.87″) and weighs 190 g (0.42 lb / 6.70 oz) (including batteries). Panasonic TS3 has external dimensions of 103 x 64 x 27 mm (4.06 x 2.52 x 1.06″) and weighs 197 g (0.43 lb / 6.95 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SD4500 IS and the Panasonic TS3. Canon SD4500 IS is clearly the smaller of the two cameras. Its body is 2mm narrower, 5mm shorter and 5mm thinner than Panasonic TS3.
Now lets look at the top view comparison of Canon SD4500 IS and Panasonic TS3.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SD4500 IS is 7g lighter than the Panasonic TS3 but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the TS3, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the SD4500 IS.
LCD Screen Size and Features
Canon SD4500 IS's 3.00" LCD screen is slightly larger than Panasonic TS3's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
