Panasonic G9 vs Sony a5000: Physical Specs and Body features Comparison

Size and weight is a big decision factor when you are trying to find the ideal camera for your needs. In this section, We are going to illustrate Panasonic G9 and Sony a5000 side-by-side from the front, back and top in their relative dimensions. Panasonic G9 has external dimensions of 137 x 97 x 92 mm (5.39 x 3.82 x 3.62″) and weighs 658 g (1.45 lb / 23.21 oz) (including batteries). Sony a5000 has external dimensions of 110 x 63 x 36 mm (4.33 x 2.48 x 1.42″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries).

Below you can see the front view size comparison of Panasonic G9 and Sony a5000. Sony a5000 is clearly the smaller of the two cameras. Its body is 27mm narrower, 34mm shorter and 56mm thinner than Panasonic G9.

Now lets look at the top view comparison of Panasonic G9 and Sony a5000.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Sony a5000 is significantly lighter (389g ) than the Panasonic G9 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 have to also take into account the lenses that you will be using with these bodies. Since Sony a5000 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 a5000 lenses.

Weather Sealing

With its weather sealed body, we believe that G9 has a big advantage over a5000 which doesn't provide any kind of environmental sealing.

LCD Screen Size and Features

Panasonic G9 and Sony a5000's LCD screens has the same diagonal size of 3.00".

Sony a5000 features a Tilting only screen which is mostly only good for shooting from waist or over the head levels. On the other hand, Panasonic G9 sports a Fully Articulated screen which is more flexible and useful especially for taking Selfie shots and video.
Panasonic G9 vs Sony a5000: Sensor Comparison

Both Panasonic G9 and Sony a5000 have 20.0 MP resolution sensors but Panasonic G9's sensor is Four Thirds (17.3 x 13 mm ) and Sony a5000's sensor is APS-C (23.2 x 15.4 mm ).

Since Sony a5000's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Panasonic G9.

Another difference between these two cameras is that Panasonic G9's sensor lacks anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

Below you can see the G9 and a5000 sensor size comparison.

Sensor Size and Resolution Comparison image of Panasonic G9 and Sony a5000 Cameras


As seen above, Sony a5000 has a 1.6x Larger sensor area than Panasonic G9. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.

Panasonic G9 vs Sony a5000 Comparison of Available Lenses
Which camera has more lenses?

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Sony a5000 has an advantage over Panasonic G9 There are 184 lenses for Sony a5000's Sony E mount, on the other hand there are only 119 lenses for Panasonic G9's Micro Four Thirds lens mount.

Another important factor is the availability of image stabilization. Panasonic G9 has a big advantage in this regard because it has a sensor based image stabilization (IS) which means that all the lenses mounted to this body will be stabilized. G9's built-in Image stabilization system is effective to compensate vibration up to 6.5-stops according to CIPA standards.
On the other hand, Sony a5000 doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 36 lenses for Sony E mount with Optical Image Stabilization features.
