Sony A7R III vs Panasonic G7: 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 Sony A7R III and Panasonic G7 side-by-side from the front, back and top in their relative dimensions. Sony A7R III has external dimensions of 127 x 96 x 74 mm (5 x 3.78 x 2.91″) and weighs 657 g (1.45 lb / 23.17 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 Sony A7R III and Panasonic G7. Panasonic G7 is 2mm narrower and 10mm shorter than Sony A7R III but it is also 3mm thicker.

Now lets look at the top view comparison of Sony A7R III 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 (247g ) than the Sony A7R III 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 A7R III has a Full frame sensor and Panasonic G7 has a smaller Four Thirds sensor, Panasonic G7's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A7R III lenses.

Weather Sealing

With its weather sealed body, we believe that A7R III has a big advantage over G7 which doesn't provide any kind of environmental sealing.

LCD Screen Size and Features

Sony A7R III and Panasonic G7's LCD screens has the same diagonal size of 3.

Sony A7R III 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 Selfie shots and video.
Sony A7R III vs Panasonic G7: Sensor Comparison

Sony A7R III has a 42.0MP Full frame (35.9 x 24 mm ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, Panasonic G7 has a 16.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor .

Sony A7R III's sensor provides 26MP more than Panasonic G7's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely. On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.

Another difference between these two cameras is that Sony A7R III'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 A7R III and G7 sensor size comparison.

Sensor Size and Resolution Comparison image of Sony A7R III and Panasonic G7 Cameras


As seen above, Sony A7R III has a 3.8x Larger sensor area than Panasonic G7. 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.

Sony A7R III vs Panasonic G7 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 A7R III has an advantage over Panasonic G7. There are 128 lenses for Sony A7R III's Sony E mount, on the other hand there are only 107 lenses for Panasonic G7's Micro Four Thirds lens mount.

Another important factor is the availability of image stabilization. Sony A7R III 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. A7R III's built-in Image stabilization system is effective to compensate vibration up to 5.0-stops according to CIPA standards.
