Panasonic G1 vs Sony RX10 III
The Panasonic Lumix DMC-G1 and the Sony Cyber-shot DSC-RX10 III are two digital cameras that were announced, respectively, in September 2008 and March 2016. The G1 is a mirrorless interchangeable lens camera, while the RX10 III is a fixed lens compact. The cameras are based on a Four Thirds (G1) and an one-inch (RX10 III) sensor. The Panasonic has a resolution of 12 megapixels, whereas the Sony provides 20 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-G1 and the Sony Cyber-shot DSC-RX10 III? 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 physical size and weight of the Panasonic G1 and the Sony RX10 III are illustrated 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 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 RX10 III is notably larger (20 percent) than the Panasonic G1. It is noteworthy in this context that the RX10 III is splash and dust-proof, while the G1 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 III has a lens built in, whereas the G1 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 G1 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the G1 gets 410 shots out of its DMW-BLB13 battery, while the RX10 III can take 420 images on a single charge of its NP-FW50 power pack. The power pack in the RX10 III 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 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. 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 G1 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 G1 has a native 4:3 aspect ratio, while the one in the RX10 III offers a 3:2 aspect.
Despite having a smaller sensor, the RX10 III offers a higher resolution of 20 megapixels, compared with 12 MP of the G1. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.33μm for the G1). However, it should be noted that the RX10 III is much more recent (by 7 years and 6 months) than the G1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Sony RX10 III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX10 III for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Panasonic G1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Panasonic Lumix DMC-G1 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Sony Cyber-shot DSC-RX10 III are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.
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 RX10 III offers substantially better image quality than the G1 (overall score 17 points higher). The advantage is based on 2 bits higher color depth, 2.3 EV in additional dynamic range, and -0 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 also of capturing video footage. The RX10 III indeed provides for movie recording, while the G1 does not. The highest resolution format that the RX10 III can use is 4K/30p.
Beyond 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 RX10 III offers a substantially higher resolution than the one in the G1 (2359k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Panasonic G1, the Sony RX10 III, and comparable cameras.

One feature that is present on the RX10 III, but is missing on the G1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The G1 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 RX10 III does not have a selfie-screen.
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, the RX10 III is one of those camera that have an additional 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 G1 writes its imaging data to SDHC cards, while the RX10 III uses SDXC or Memory Stick PRO Duo cards. The RX10 III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1 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-G1 and Sony Cyber-shot DSC-RX10 III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX10 III offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G1 does not provide wifi capability.
The RX10 III is a recent model that features in the current product line-up of Sony. In contrast, the G1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G1 was succeeded by the Panasonic G2. 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 conclusions can be drawn? Is there a clear favorite between the Panasonic G1 and the Sony RX10 III? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Panasonic Lumix DMC-G1:
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.

If the count of relative strengths (bullet points above) is taken as a measure, the RX10 III is the clear winner of the contest (18 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 G1 and the Sony RX10 III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom 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 incomplete and does no justice, for example, to the way the G1 or the RX10 III 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
