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 H90 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 H90 has external dimensions of 105 x 60 x 34 mm (4.13 x 2.36 x 1.34″) and weighs 222 g (0.49 lb / 7.83 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus SZ-30MR and the Sony H90. Sony H90 is clearly the smaller of the two cameras. Its body is 1mm narrower, 9mm shorter and 6mm thinner than Olympus SZ-30MR.
Now lets look at the top view comparison of Olympus SZ-30MR and Sony H90.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony H90 is 4g lighter than the Olympus SZ-30MR but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Olympus SZ-30MR nor Sony Cyber-shot DSC-H90 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 H90'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.
