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 XZ-10 and Panasonic GF7 side-by-side from the front, back and top in their relative dimensions. Olympus XZ-10 has external dimensions of 102 x 61 x 34 mm (4.03 x 2.41 x 1.35″) and weighs 221 g (0.49 lb / 7.80 oz) (including batteries). Panasonic GF7 has external dimensions of 107 x 65 x 33 mm (4.21 x 2.56 x 1.3″) and weighs 266 g (0.59 lb / 9.38 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus XZ-10 and the Panasonic GF7. Olympus XZ-10 is 5mm narrower and 4mm shorter than Panasonic GF7 but it is also 1mm thicker. As you can tell, actually this is not a fair size comparison since Olympus XZ-10 has a built-in lens but Panasonic GF7 doesn't. Once you put a lens on GF7, its thickness will increase significantly.
Here is the back view size comparison of the Olympus XZ-10 and Panasonic GF7.
Now lets look at the top view comparison of Olympus XZ-10 and Panasonic GF7.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus XZ-10 is significantly lighter (45g ) than the Panasonic GF7 which may become a big advantage especially on long walking trips.
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 GF7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Olympus Stylus XZ-10 nor Panasonic Lumix DMC-GF7 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 XZ-10 and Panasonic GF7's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Panasonic GF7 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Olympus XZ-10 has a fixed type screen which provides less flexibility in shooting positions compared to GF7.
