Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX1R and the Canon EOS M6? 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

The side-by-side display below illustrates the physical size and weight of the Sony RX1R and the Canon M6. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The M6 can be obtained in two different colors (black, silver), while the RX1R is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M6 is somewhat larger (4 percent) than the Sony RX1R. In this context, it is worth noting that neither the RX1R nor the M6 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R has a lens built in, whereas the M6 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the RX1R gets 270 shots out of its Sony NP-BX1 battery, while the M6 can take 295 images on a single charge of its Canon LP-E17 power pack. The power pack in the RX1R 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.

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. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Sony RX1R features a full frame sensor and the Canon M6 an APS-C sensor. The sensor area in the M6 is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the RX1R has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the RX1R has a lower pixel density and larger individual pixels (with a pixel pitch of 5.97μm versus 3.72μm for the M6), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the M6 is much more recent (by 3 years and 7 months) than the RX1R, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the RX1R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The M6 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Cyber-shot DSC-RX1R 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 Canon EOS M6 are ISO 100 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 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 RX1R provides substantially higher image quality than the M6, with an overall score that is 13 points higher. This advantage is based on 1.6 bits higher color depth, 1 EV in additional dynamic range, and 0.9 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 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, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The RX1R and the M6 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. However, optional viewfinders – the FDA-EV1MK for the RX1R and the EVF-DC2 for the M6 – are available as accessories. The adjacent table lists some of the other core features of the Sony RX1R and Canon M6 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M6 has a touchscreen, while the RX1R has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon M6 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 RX1R writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the M6 uses SDXC cards. The M6 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the RX1R 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 and Canon EOS M6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the RX1R does not provide wifi capability.

Both the RX1R and the M6 have been discontinued, but can regularly be found used on ebay. The RX1R was replaced by the Sony RX1R II, while the M6 was followed by the Canon M6 Mark II. Further information on the features and operation of the RX1R and M6 can be found, respectively, in the Sony RX1R Manual (free pdf) or the online Canon M6 Manual.

Review summary

So how do things add up? Which of the two cameras – the Sony RX1R or the Canon M6 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Sony Cyber-shot DSC-RX1R:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (13 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.6 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (0.9 stops ISO advantage).
• More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
• Ready to shoot: Has a lens built-in, whereas the M6 requires a separate lens.
• Easier travel charging: Can be conveniently charged via its USB port.
• More heavily discounted: Has been available for much longer (launched in June 2013).

Advantages of the Canon EOS M6:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (9 vs 5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• 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.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 3 years and 7 months of technical progress since the RX1R launch.

If the count of individual advantages (bullet points above) is taken as a guide, the M6 is the clear winner of the contest (13 : 9 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 before making a decision 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 Sony RX1R and the Canon M6 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 and the M6 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 why expert reviews are important. 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.

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.
