Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-GH6 and the Panasonic Lumix DC-S1R II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Panasonic GH6 and the Panasonic S1R II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH6 and the Panasonic S1R II are of equal size. However, the S1R II is slightly lighter (3 percent) than the GH6. 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

The power pack in the S1R II can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The GH6 was launched at a markedly lower price (by 33 percent) than the S1R II, which puts it into a different market segment. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 GH6 features a Four Thirds sensor and the Panasonic S1R II a full frame sensor. The sensor area in the S1R II is 280 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the GH6 has a native 4:3 aspect ratio, while the one in the S1R II offers a 3:2 aspect.

With 44.2MP, the S1R II offers a higher resolution than the GH6 (25MP), but the S1R II nevertheless has larger individual pixels (pixel pitch of 4.40μm versus 3.00μm for the GH6) due to its larger sensor. Moreover, the S1R II is a much more recent model (by 3 years and 2 months) than the GH6, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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.

The resolution advantage of the Panasonic S1R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1R II for good quality output (200 dots per inch) amounts to 40.7 x 27.1 inches or 103.4 x 68.9 cm, for very good quality (250 dpi) 32.6 x 21.7 inches or 82.7 x 55.1 cm, and for excellent quality (300 dpi) 27.1 x 18.1 inches or 69 x 45.9 cm. The corresponding values for the Panasonic GH6 are 28.9 x 21.7 inches or 73.4 x 55.1 cm for good quality, 23.1 x 17.3 inches or 58.7 x 44.1 cm for very good quality, and 19.3 x 14.5 inches or 48.9 x 36.7 cm for excellent quality prints.

The S1R II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Both cameras have the capacity to capture high quality composite images by combining multiple shots after shifting the sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Panasonic Lumix DC-GH6 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-25600. The corresponding ISO settings for the Panasonic Lumix DC-S1R II are ISO 80 to ISO 51200, with the possibility to increase the ISO range to 40-102400.

In terms of underlying technology, the GH6 is build around a CMOS sensor, while the S1R II uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the S1R II provides a better video resolution than the GH6. It can shoot movie footage at 8K/30p, while the GH6 is limited to 5.7K/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the S1R II offers a substantially higher resolution than the one in the GH6 (5760k vs 3680k dots). The adjacent table lists some of the other core features of the Panasonic GH6 and Panasonic S1R II along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic GH6 and the Panasonic S1R II both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the GH6 and the S1R II write their files to CFexpress (type B) or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Panasonic Lumix DC-GH6 and Panasonic Lumix DC-S1R II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the GH6 and the S1R II are recent models that are part of the current product line-up. The GH6 replaced the earlier Panasonic GH5 II, while the S1R II followed on from the Panasonic S1R. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.

Review summary

So what is the bottom line? Which of the two cameras – the Panasonic GH6 or the Panasonic S1R II – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Panasonic Lumix DC-GH6:

• Faster burst: Shoots at higher frequency (14 vs 9 flaps/sec) to capture the decisive moment.
• More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in February 2022).

Arguments in favor of the Panasonic Lumix DC-S1R II:

• More detail: Has more megapixels (44.2 vs 25MP), which boosts linear resolution by 35%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher definition movie capture (8K/30p vs 5.7K/60p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 3680k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.76x).
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• Easier travel charging: Can be conveniently charged via its USB port.
• More modern: Reflects 3 years and 2 months of technical progress since the GH6 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the S1R II is the clear winner of the contest (12 : 3 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Panasonic GH6 and the Panasonic S1R II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GH6 or the S1R II. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
