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 SZ-30MR and Sony HX30V side-by-side from the front, back and top in their relative dimensions. Olympus SZ-30MR has external dimensions of 106 x 69 x 40 mm (4.17 x 2.72 x 1.57″) and weighs 226 g (0.50 lb / 7.97 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Olympus SZ-30MR and the Sony HX30V. Sony HX30V is 7mm shorter and 5mm thinner than Olympus SZ-30MR but it is also 1mm wider.
Now lets look at the top view comparison of Olympus SZ-30MR and Sony HX30V.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus SZ-30MR is 28g lighter than the Sony HX30V but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus SZ-30MR nor Sony Cyber-shot DSC-HX30V 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
Olympus SZ-30MR and Sony HX30V'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.
