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 Sony HX30V and Olympus TG-4 side-by-side from the front, back and top in their relative dimensions. Sony HX30V has external dimensions of 107 x 62 x 35 mm (4.21 x 2.44 x 1.38″) and weighs 254 g (0.56 lb / 8.96 oz) (including batteries). Olympus TG-4 has external dimensions of 112 x 66 x 31 mm (4.41 x 2.6 x 1.22″) and weighs 247 g (0.54 lb / 8.71 oz) (including batteries).
Below you can see the front-view size comparison of the Sony HX30V and the Olympus TG-4. Sony HX30V is 5mm narrower and 4mm shorter than Olympus TG-4 but it is also 4mm thicker.
Here is the back view size comparison of the Sony HX30V and Olympus TG-4.
Now lets look at the top view comparison of Sony HX30V and Olympus TG-4.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-4 is 7g lighter than the Sony HX30V but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the TG-4, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the HX30V.
LCD Screen Size and Features
Sony HX30V and Olympus TG-4's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
