Panasonic G9 vs Nikon D7100 Comparison Overview

Here we are comparing two cameras with different body types: Panasonic G9, which was introduced in November 2017 is a Advanced Mirrorless camera with a 20.0MP Four Thirds sensor whereas Nikon D7100, which was introduced in April 2013 is a Advanced DSLR camera with a 24.0MP APS-C sensor. As you can see, D7100 is 4 years older than G9. Let's see if this age difference between two cameras makes a big difference.

Despite some fundamental differences of these two body types, Mirrorless cameras are becoming serious alternatives to DSLR cameras thanks to their size/weight advantages and recent improvements in their focus speeds , which makes this comparison even more interesting.

Here is a brief look at the main features of the Panasonic G9 and Nikon D7100 before getting into our more detailed comparison.

Common Weaknesses of Panasonic Lumix DC-G9 and Nikon D7100

Panasonic G9 vs Nikon D7100: Physical Specs and Body Features Comparison

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 Nikon D7100 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). Nikon D7100 has external dimensions of 136 x 107 x 76 mm (5.35 x 4.21 x 2.99″) and weighs 765 g (1.69 lb / 26.98 oz) (including batteries).

Below you can see the front-view size comparison of the Panasonic G9 and the Nikon D7100. Nikon D7100 is 1mm narrower and 16mm thinner than Panasonic G9 but it is also 10mm taller.

Now lets look at the top view comparison of Panasonic G9 and Nikon D7100.

Top View Comparison image of the Panasonic G9 and the Nikon D7100 Size

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day. Panasonic G9 is significantly lighter (107g ) than the Nikon D7100 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 Nikon D7100 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 Nikon D7100 lenses.

Weather Sealing

Both the G9 and the D7100 have weather sealings in their bodies, making them resistant to water and dust.

LCD Screen Size and Features

Nikon D7100's 3.20" LCD screen is slightly larger than Panasonic G9's 3 screen.

On the other hand, Panasonic G9 sports a Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Nikon D7100 has a fixed type screen which provides almost no flexibility in shooting positions compared to G9.

Panasonic G9 vs Nikon D7100: Sensor Comparison

Panasonic G9 has a 20.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor . On the other hand, Nikon D7100 has a 24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor .

Another similarity between these two cameras is that both Nikon D7100 and Panasonic G9 sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.

Below you can see the G9 and D7100 sensor size comparison.

Sensor Size and Resolution Comparison image of Panasonic G9 and Nikon D7100 Cameras

As seen above, Nikon D7100 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 Nikon D7100 Comparison of Available Lenses

Which camera has more lenses?

The number of available lenses is a big deciding factor when choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that the Nikon D7100 has an advantage over the Panasonic G9 There are 316 lenses for the Nikon D7100's Nikon F mount, but on the other hand, there are only 123 lenses for the 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 for compensating vibration up to 6.5-stops according to CIPA standards.
On the other hand, Nikon D7100 doesn't have this feature so you have to buy a lens with optical stabilization feature. Currently there are 107 lenses for Nikon F mount with Optical Image Stabilization features.
