Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX100 IV and the Canon EOS M50? 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 RX100 IV and the Canon M50. 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.

The M50 can be obtained in two different colors (black, white), while the RX100 IV 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 M50 is considerably larger (73 percent) than the Sony RX100 IV. In this context, it is worth noting that neither the RX100 IV nor the M50 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 IV has a lens built in, whereas the M50 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 RX100 IV gets 280 shots out of its Sony NP-BX1 battery, while the M50 can take 235 images on a single charge of its Canon LP-E12 power pack. The power pack in the RX100 IV can be charged via the USB port, so that it is not always necessary to take the battery charger along 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.

Sensor comparison

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 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. 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 Sony RX100 IV features an one-inch sensor and the Canon M50 an APS-C sensor. The sensor area in the M50 is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 24MP, the M50 offers a higher resolution than the RX100 IV (20MP), but the M50 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the RX100 IV) due to its larger sensor. Moreover, the M50 is a much more recent model (by 2 years and 8 months) than the RX100 IV, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon M50 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M50 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony RX100 IV are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The M50 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Cyber-shot DSC-RX100 IV has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Canon EOS M50 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

In terms of underlying technology, the RX100 IV is build around a BSI-CMOS sensor, while the M50 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.

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"). 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, but the RX100 IV provides a higher frame rate than the M50. It can shoot video footage at 4K/30p, while the Canon is limited to 4K/24p.

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 M50 offers a slightly higher resolution than the one in the RX100 IV (2360k vs 2359k dots). The following table reports on some other key feature differences and similarities of the Sony RX100 IV, the Canon M50, and comparable cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M50 has a touchscreen, while the RX100 IV has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 RX100 IV 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 Canon M50 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 RX100 IV writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the M50 uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 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 Sony Cyber-shot DSC-RX100 IV and Canon EOS M50 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M50 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The RX100 IV does not feature such a mic input.

Both the RX100 IV and the M50 have been discontinued, but can regularly be found used on ebay. The RX100 IV was replaced by the Sony RX100 IV, while the M50 was followed by the Canon M50 Mark II. Further information on the features and operation of the RX100 IV and M50 can be found, respectively, in the Sony RX100 IV Manual (free pdf) or the online Canon M50 Manual.

Review summary

So what is the bottom line? Is the Sony RX100 IV better than the Canon M50 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Sony Cyber-shot DSC-RX100 IV:

• Better video: Provides higher movie framerates (4K/30p versus 4K/24p).
• More detailed LCD: Has a higher resolution rear screen (1228k vs 1040k dots).
• Faster burst: Shoots at higher frequency (16 vs 10 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Has a lens built-in, whereas the M50 requires a separate lens.
• More compact: Is smaller (102x58mm vs 116x88mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the M50).
• Longer lasting: Can take more shots (280 versus 235) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been available for much longer (launched in June 2015).

Arguments in favor of the Canon EOS M50:

• More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
• 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 live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• 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.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 2 years and 8 months of technical progress since the RX100 IV launch.

If the count of individual advantages (bullet points above) is taken as a guide, the M50 emerges as the winner of the match-up (15 : 12 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 RX100 IV and the Canon M50 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 RX100 IV or the M50. 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.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 review scores listed above should be treated 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.
