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-2 iHS and Panasonic G7 side-by-side from the front, back and top in their relative dimensions. Olympus XZ-2 iHS has external dimensions of 113 x 65 x 48 mm (4.45 x 2.56 x 1.89″) and weighs 346 g (0.76 lb / 12.20 oz) (including batteries). Panasonic G7 has external dimensions of 125 x 86 x 77 mm (4.92 x 3.39 x 3.03″) and weighs 410 g (0.90 lb / 14.46 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus XZ-2 iHS and the Panasonic G7. Olympus XZ-2 iHS is clearly the smaller of the two cameras. Its body is 12mm narrower, 21mm shorter and 29mm thinner than Panasonic G7. As you can tell, actually this is not a fair size comparison since Olympus XZ-2 iHS has a built-in lens but Panasonic G7 doesn't. Once you put a lens on G7, its thickness will increase significantly.
Now lets look at the top view comparison of Olympus XZ-2 iHS and Panasonic G7.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus XZ-2 iHS is significantly lighter (64g ) than the Panasonic G7 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 G7, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Olympus XZ-2 iHS nor Panasonic Lumix DMC-G7 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-2 iHS and Panasonic G7's LCD screens have the same diagonal size of 3.00 inches.
Olympus XZ-2 iHS features a
Tilting-only screen which is mostly only good for shooting from waist or over-the-head levels. On the other hand, Panasonic G7 sports a
Fully Articulated screen which is more flexible and useful, especially for taking selfies and video.
