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 G9 and Sony A65 side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A65 is 36g lighter than the Panasonic G9 but we don't think this will make a significant difference.
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 Sony A65 has an APS-C sized sensor and Panasonic G9 has a smaller Four Thirds sensor, Panasonic G9's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A65 lenses.
Weather Sealing
With its weather-sealed body, we believe that the G9 has a big advantage over the A65 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Panasonic G9 and Sony A65'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.
