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 Samsung HZ35W and Olympus E-PM2 side-by-side from the front, back and top in their relative dimensions. Samsung HZ35W has external dimensions of 107 x 61 x 28 mm (4.21 x 2.4 x 1.1″) and weighs 245 g (0.54 lb / 8.64 oz) (including batteries). Olympus E-PM2 has external dimensions of 110 x 64 x 34 mm (4.33 x 2.52 x 1.34″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung HZ35W and the Olympus E-PM2. Samsung HZ35W is clearly the smaller of the two cameras. Its body is 3mm narrower, 3mm shorter and 6mm thinner than Olympus E-PM2. As you can tell, actually this is not a fair size comparison since Samsung HZ35W has a built-in lens but Olympus E-PM2 doesn't. Once you put a lens on E-PM2, its thickness will increase significantly.
Now lets look at the top view comparison of Samsung HZ35W and Olympus E-PM2.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung HZ35W is 24g lighter than the Olympus E-PM2 but we don't think this will make a significant difference.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on E-PM2, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Samsung HZ35W (WB650) nor Olympus PEN E-PM2 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
Samsung HZ35W and Olympus E-PM2'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.
