Panasonic GH5 versus Sony RX10 III
The Panasonic Lumix DC-GH5 and the Sony Cyber-shot DSC-RX10 III are two enthusiast cameras that were officially introduced, respectively, in January 2017 and March 2016. The GH5 is a mirrorless interchangeable lens camera, while the RX10 III is a fixed lens compact. The cameras are based on a Four Thirds (GH5) and an one-inch sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Sony provides 20 MP.
An illustration of the physical size and weight of the Panasonic GH5 and the Sony RX10 III is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the GH5 – 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 Sony RX10 III is somewhat smaller (8 percent) than the Panasonic GH5. 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 and possibly misleading, as the RX10 III has a lens build in, whereas the GH5 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the GH5 and their specifications in the Micro Four Thirds Lens Catalog.
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 RX10 III was launched at a lower price than the GH5, despite having a lens build in. 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 sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GH5 features a Four Thirds sensor and the Sony RX10 III an one-inch sensor. The sensor area in the RX10 III is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the GH5 has a native 4:3 aspect ratio, while the one in the RX10 III offers a 3:2 aspect.
With 20.2MP, the GH5 offers a higher resolution than the RX10 III (20MP), but the GH5 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX10 III) due to its larger sensor. Moreover, the GH5 is a somewhat more recent model (by 9 months) than the RX10 III, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GH5 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
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"). Of the two cameras under review, the GH5 has a notably higher overall DXO score than the RX10 III (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.4 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GH5 provides a higher frame rate than the RX10 III. It can shoot video footage at 4K/60p, while the Sony is limited to 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GH5 offers a substantially higher resolution than the one in the RX10 III (3680k vs 2359k dots). The adjacent table lists some of the other core features of the Panasonic GH5 and Sony RX10 III along with similar information for a selection of comparators.

The GH5 is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX10 III has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX10 III was succeeded by the Sony RX10 IV.
So how do things add up? Which of the two cameras – the Panasonic GH5 or the Sony RX10 III – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Panasonic Lumix DC-GH5:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
- Better video: Provides higher movie framerates (4K/60p vs 4K/30p).
- More detailed viewfinder: Has a higher resolution electronic viewfinder (3680k vs 2359k dots).
- 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 1229k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More modern: Is somewhat more recent (announced 9 months after the RX10 III).
Reasons to prefer the Sony Cyber-shot DSC-RX10 III:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier setting verification: Has a control panel on top to check shooting parameters.
- Ready to shoot: Has an integrated lens, whereas the GH5 necessitates an extra lens.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced at a lower price, despite coming with a build-in lens.
- More heavily discounted: Has been on the market for longer (launched in March 2016).
If the number of relative strengths (bullet points above) is taken as a guide, the GH5 is the clear winner of the match-up (13 : 6 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 says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GH5 and the RX10 III in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
