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 FZ300 and Panasonic G7 side-by-side from the front, back and top in their relative dimensions. Panasonic FZ300 has external dimensions of 132 x 92 x 117 mm (5.2 x 3.62 x 4.61″) and weighs 691 g (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 Panasonic FZ300 and the Panasonic G7. Panasonic G7 is clearly the smaller of the two cameras. Its body is 7mm narrower, 6mm shorter and 40mm thinner than Panasonic FZ300. As you can tell, actually this is not a fair size comparison since Panasonic FZ300 has a built-in lens but Panasonic G7 doesn't. Once you put a lens on G7, its thickness will increase significantly.
Here is the back view size comparison of the Panasonic FZ300 and Panasonic G7.
Now lets look at the top view comparison of Panasonic FZ300 and Panasonic G7.
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 (281g ) than the Panasonic FZ300 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
With its weather-sealed body, we believe that the FZ300 has a big advantage over the G7 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Panasonic FZ300 and Panasonic G7's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Fully Articulating screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. Fully articulating screens are also useful for taking Selfies and video.
