Canon G9 X Mark II vs Samsung NX30
The Canon PowerShot G9 X Mark II and the Samsung NX30 are two digital cameras that were revealed to the public, respectively, in January 2017 and January 2014. The G9X Mark II is a fixed lens compact, while the NX30 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G9X Mark II) and an APS-C (NX30) sensor. Both cameras offer a resolution of 20 megapixels.
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 Canon PowerShot G9 X Mark II 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.
An illustration of the physical size and weight of the Canon G9 X Mark II and the Samsung NX30 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The G9X Mark II 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 (114 percent) than the Canon G9 X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the NX30 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X Mark II has a lens built in, whereas the NX30 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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. The G9X Mark II was launched at a lower price than the NX30, despite having a lens built in. 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.
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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G9 X Mark II features an one-inch sensor and the Samsung NX30 an APS-C sensor. The sensor area in the NX30 is 218 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Even though the NX30 has a larger sensor, both cameras offer the same resolution of 20 megapixels. This implies that the NX30 has a lower pixel density and larger individual pixels (with a pixel pitch of 4.30μm versus 2.41μm for the G9X Mark II), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the G9X Mark II is much more recent (by 3 years) than the NX30, 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 NX30 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The NX30 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G9 X Mark II has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Samsung NX30 are ISO 100 to ISO 25600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the NX30 offers substantially better image quality than the G9X Mark II (overall score 11 points higher). The advantage is based on 1.6 bits higher color depth, 0.1 EV of lower dynamic range, and 1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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).
Beyond 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 G9X Mark II relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G9 X Mark II and Samsung NX30 along with similar information for a selection of comparators.

The Canon G9 X Mark II 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 G9X Mark II 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.
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 PowerShot G9 X Mark II 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 NX30 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The G9X Mark II does not feature such an accessory-socket.
The G9X Mark II is a recent model that features in the current product line-up of Canon. In contrast, the NX30 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the NX30 from Samsung. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Samsung websites.
So how do things add up? Which of the two cameras – the Canon G9 X Mark II or the Samsung NX30 – 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 Canon PowerShot G9 X Mark II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Ready to shoot: Has a lens built-in, whereas the NX30 requires a separate lens.
- More compact: Is smaller (98x58mm vs 127x96mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the NX30).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 3 years of technical progress since the NX30 launch.
Arguments in favor of the Samsung NX30:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
- Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- 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.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (360 versus 235) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in January 2014).
If the number of relative strengths (bullet points above) is taken as a guide, the NX30 is the clear winner of the contest (13 : 8 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 Canon G9 X Mark II and the Samsung NX30 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 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 G9X Mark II and the NX30 in practical situations. 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.
This is why expert reviews 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 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.
