Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M6 and the Samsung NX30? 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 Canon M6 and the Samsung NX30. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

The M6 can be obtained in two different colors (black, silver), while the NX30 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 Samsung NX30 is considerably larger (60 percent) than the Canon M6. However, the NX30 is slightly lighter (4 percent) than the M6. In this context, it is worth noting that neither the M6 nor the NX30 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

The power pack in the NX30 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. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Convert to Imperial

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M6 was launched at a somewhat lower price (by 22 percent) than the NX30, which makes it more attractive for photographers on a tight budget. 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 sensor inside a digital camera is one of the key determinants 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. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NX30 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (M6) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Canon M6 offers a higher resolution of 24 megapixels, compared with 20 MP of the Samsung NX30. 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 3.72μm versus 4.30μm for the NX30). However, it should be noted that the M6 is much more recent (by 3 years and 1 month) than the NX30, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the NX30 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon M6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M6 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 Samsung NX30 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 Canon EOS M6 has a native sensitivity range from ISO 100 to ISO 25600. The Samsung NX30 offers exactly the same ISO settings.

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 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the NX30 has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M6 relies on live view and the rear LCD for framing. That said, the M6 can be equipped with an optional viewfinder – the EVF-DC2. The table below summarizes some of the other core capabilities of the Canon M6 and Samsung NX30 in connection with corresponding information for a sample of similar cameras.

The Canon M6 and the Samsung NX30 both have 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.

Concerning the storage of imaging data, both the M6 and the NX30 write their files to 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 Canon EOS M6 and Samsung NX30 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 has a microphone port, which is missing on the NX30. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the M6 and the NX30 have been discontinued, but can regularly be found used on ebay. The M6 was replaced by the Canon M6 Mark II, while the NX30 does not have a direct successor. Further information on the features and operation of the M6 and NX30 can be found, respectively, in the Canon M6 Manual (free pdf) or the online Samsung NX30 Manual.

Review summary

So how do things add up? Is the Canon M6 better than the Samsung NX30 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS M6:

• More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More compact: Is smaller (112x68mm vs 127x96mm) and thus needs less room in the bag.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced segment (22 percent cheaper at launch).
• More modern: Reflects 3 years and 1 month of technical progress since the NX30 launch.

Advantages of the Samsung NX30:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Longer lasting: Gets more shots (360 versus 295) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• More heavily discounted: Has been around for much longer (launched in January 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the M6 comes out slightly ahead of the NX30 (8 : 7 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Canon M6 and the Samsung NX30 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 M6 or the NX30 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
