Panasonic G9 versus Panasonic GH5
The Panasonic Lumix DC-G9 and the Panasonic Lumix DC-GH5 are two enthusiast cameras that were officially introduced, respectively, in November 2017 and January 2017. Both the G9 and the GH5 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 20.2 megapixel.
An illustration of the physical size and weight of the Panasonic G9 and the Panasonic GH5 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the G9 – represents the basis for the calculations across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH5 is somewhat larger (3 percent) than the Panasonic G9. Moreover, the GH5 is markedly heavier (10 percent) than the G9. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G9 was launched at a somewhat lower price (by 15 percent) than the GH5, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20.2 megapixel. This similarity in sensor specs implies that both the G9 and the GH5 have the same pixel density, as well as the same pixel size. It should, however, be noted that the G9 is a somewhat more recent model (by 10 months) than the GH5, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
Unlike the GH5, the G9 has the capacity to capture high quality composite images (80.6MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/60p).
Apart from body and sensor, cameras can and do differ across a range of features. The G9 and the GH5 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 3680k dots. The adjacent table lists some of the other core features of the Panasonic G9 and Panasonic GH5 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the G9 and the GH5 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GH5 replaced the earlier Panasonic GH4, while the G9 followed on from the Panasonic G85.
So what is the bottom line? Is the Panasonic G9 better than the Panasonic GH5 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Panasonic Lumix DC-G9:
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Easier setting verification: Has an LCD display on top to control shooting parameters.
- Faster burst: Shoots at higher frequency (20 vs 12 flaps/sec) to capture the decisive moment.
- More affordable: Was introduced into a lower priced segment (15 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 10 months after the GH5).
Advantages of the Panasonic Lumix DC-GH5:
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
- More heavily discounted: Has been on the market for longer (launched in January 2017).
If the number of relative strengths (bullet points above) is taken as a guide, the G9 emerges as the winner of the contest (5 : 3 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G9 or the GH5 handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
