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 Panasonic G7 and Olympus E-M1 side-by-side from the front, back and top in their relative dimensions. 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). Olympus E-M1 has external dimensions of 130 x 94 x 63 mm (5.13 x 3.68 x 2.48″) and weighs 497 g (1.10 lb / 17.53 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic G7 and the Olympus E-M1. Panasonic G7 is 5mm narrower and 8mm shorter than Olympus E-M1 but it is also 14mm thicker.
Here is the back view size comparison of the Panasonic G7 and Olympus E-M1.
Now lets look at the top view comparison of Panasonic G7 and Olympus E-M1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic G7 is significantly lighter (87g ) than the Olympus E-M1 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Panasonic G7 and Olympus E-M1 have the same Micro Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Thanks to the weather-sealed body of the E-M1, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the G7.
LCD Screen Size and Features
Panasonic G7 and Olympus E-M1's LCD screens have the same diagonal size of 3.00 inches.
Olympus E-M1 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.
