Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX1R II and the Panasonic Lumix DMC-GF1? 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 Sony RX1R II and the Panasonic GF1 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 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 Panasonic GF1 is notably larger (15 percent) than the Sony RX1R II. In this context, it is worth noting that neither the RX1R II nor the GF1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R II has a lens built in, whereas the GF1 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 GF1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the RX1R II gets 220 shots out of its Sony NP-BX1 battery, while the GF1 can take 380 images on a single charge of its Panasonic DMW-BLB13 power pack. The power pack in the RX1R II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Any camera decision will naturally be influenced heavily by the price. 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. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX1R II features a full frame sensor and the Panasonic GF1 a Four Thirds sensor. The sensor area in the GF1 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the RX1R II has a native 3:2 aspect ratio, while the one in the GF1 offers a 4:3 aspect.

With 42.2MP, the RX1R II offers a higher resolution than the GF1 (12MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 4.33μm for the GF1) due to its larger sensor. Moreover, the RX1R II is a much more recent model (by 6 years and 1 month) than the GF1, and its sensor will 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 RX1R II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX1R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Panasonic GF1 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 Sony Cyber-shot DSC-RX1R II has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Panasonic Lumix DMC-GF1 are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the RX1R II is build around a BSI-CMOS sensor, while the GF1 uses a 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the RX1R II provides substantially higher image quality than the GF1, with an overall score that is 43 points higher. This advantage is based on 4.6 bits higher color depth, 3.6 EV in additional dynamic range, and 2.6 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 RX1R II provides a higher video resolution than the GF1. It can shoot video footage at 1080/60p, while the Panasonic is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX1R II has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GF1 relies on live view and the rear LCD for framing. That said, the GF1 can be equipped with an optional viewfinder – the DMW-LVF1. The table below summarizes some of the other core capabilities of the Sony RX1R II and Panasonic GF1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The GF1 has one, while the RX1R II does not. While the built-in flash of the GF1 is not very powerful, it can at times be useful as a fill-in light.

The RX1R II writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the GF1 uses SDHC cards. The RX1R II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GF1 cannot take advantage of Ultra High Speed SD cards.

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 Sony Cyber-shot DSC-RX1R II and Panasonic Lumix DMC-GF1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX1R II has a microphone port, which is missing on the GF1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the RX1R II and the GF1 have been discontinued, but can regularly be found used on ebay. The GF1 was replaced by the Panasonic DMC-GF2, while the RX1R II does not have a direct successor. Further information on the features and operation of the RX1R II and GF1 can be found, respectively, in the Sony RX1R II Manual (free pdf) or the online Panasonic GF1 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Sony RX1R II or the Panasonic GF1 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Sony Cyber-shot DSC-RX1R II:

• More detail: Offers more megapixels (42.2 vs 12MP) with a 91% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (43 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (4.6 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (3.6 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.6 stops ISO advantage).
• Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 460k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the GF1 requires a separate lens.
• More compact: Is smaller (113x65mm vs 119x71mm) and thus needs less room in the bag.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 6 years and 1 month of technical progress since the GF1 launch.

Reasons to prefer the Panasonic Lumix DMC-GF1:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (380 versus 220) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More heavily discounted: Has been around for much longer (launched in September 2009).

If the count of individual advantages (bullet points above) is taken as a guide, the RX1R II is the clear winner of the match-up (19 : 5 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 Sony RX1R II and the Panasonic GF1 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the RX1R II and the GF1 in practical situations. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Thus, a score needs to be put into the context of the launch date and the launch price 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, please note that some of the review sites have changed their methodology and reporting over time.
