Panasonic GH3 vs Sony RX1
The Panasonic Lumix DMC-GH3 and the Sony Cyber-shot DSC-RX1 are two enthusiast cameras that were revealed to the public in September 2012. The GH3 is a mirrorless interchangeable lens camera, while the RX1 is a fixed lens compact. The cameras are based on a Four Thirds (GH3) and a full frame (RX1) sensor. The Panasonic has a resolution of 15.9 megapixels, whereas the Sony provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GH3 and the Sony Cyber-shot DSC-RX1? 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.
The side-by-side display below illustrates the physical size and weight of the Panasonic GH3 and the Sony RX1. 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 measures 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 Sony RX1 is considerably smaller (41 percent) than the Panasonic GH3. It is worth mentioning in this context that the GH3 is splash and dust resistant, while the RX1 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1 has a lens built in, whereas the GH3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the GH3 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the GH3 gets 540 shots out of its DMW-BLF19 battery, while the RX1 can take 270 images on a single charge of its NP-BX1 power pack. The power pack in the RX1 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Panasonic GH3 features a Four Thirds sensor and the Sony RX1 a full frame sensor. The sensor area in the RX1 is 279 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 GH3 has a native 4:3 aspect ratio, while the one in the RX1 offers a 3:2 aspect.
With 24MP, the RX1 offers a higher resolution than the GH3 (15.9MP), but the RX1 nevertheless has larger individual pixels (pixel pitch of 5.96μm versus 3.76μm for the GH3) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Sony RX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Panasonic GH3 are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.
The Panasonic Lumix DMC-GH3 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 consideration, the RX1 offers substantially better image quality than the GH3 (overall score 22 points higher). The advantage is based on 2.4 bits higher color depth, 1.9 EV in additional dynamic range, and 1.6 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH3 has an electronic viewfinder (1746k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX1 relies on live view and the rear LCD for framing. That said, the RX1 can be equipped with an optional viewfinder – the FDA-EV1MK. The following table reports on some other key feature differences and similarities of the Panasonic GH3, the Sony RX1, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GH3 has a touchscreen, while the RX1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The GH3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the RX1 does not have a selfie-screen.
The Panasonic GH3 has 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.
The GH3 writes its imaging data to SDXC cards, while the RX1 uses SDXC or Memory Stick PRO Duo cards. The GH3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the RX1 cannot take advantage of Ultra High Speed SD cards.
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 DMC-GH3 and Sony Cyber-shot DSC-RX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH3 offers wifi support, while the RX1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Panasonic GH3 (unlike the RX1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the GH3 and the RX1 have been discontinued, but can regularly be found used on eBay. The RX1 was replaced by the Sony RX1R, while the GH3 was followed by the Panasonic GH4. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.
So what is the bottom line? Is the Panasonic GH3 better than the Sony RX1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Panasonic Lumix DMC-GH3:
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- 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.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Longer lasting: Can take more shots (540 versus 270) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
Arguments in favor of the Sony Cyber-shot DSC-RX1:
- More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
- Better image quality: Scores substantially higher (22 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.4 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
- More detailed LCD: Has a higher resolution rear screen (1229k vs 614k dots).
- Ready to shoot: Has an integrated lens, whereas the GH3 necessitates an extra lens.
- More compact: Is smaller (113x65mm vs 133x93mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the GH3).
- Easier travel charging: Can be conveniently charged via its USB port.
If the count of individual advantages (bullet points above) is taken as a guide, the GH3 is the clear winner of the match-up (13 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 GH3 and the Sony RX1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GH3 or the RX1. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

The above review scores should be interpreted 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
