Canon G9 X vs Sony HX99
The Canon PowerShot G9 X and the Sony Cyber-shot DSC-HX99 are two digital cameras that were officially introduced, respectively, in October 2015 and August 2018. Both the G9X and the HX99 are fixed lens compact cameras that are based on an one-inch (G9X) and a 1/2.3-inch (HX99) sensor. The Canon has a resolution of 20 megapixels, whereas the Sony provides 18 MP.
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 and the Sony Cyber-shot DSC-HX99? 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 and the Sony HX99 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 width, height and depth measures are rounded to the nearest millimeter.
The G9X can be obtained in two different colors (black, silver), while the HX99 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 Sony HX99 is somewhat larger (4 percent) than the Canon G9 X. Moreover, the HX99 is markedly heavier (16 percent) than the G9X. In this context, it is worth noting that neither the G9X nor the HX99 are weather-sealed.
Concerning battery life, the G9X gets 220 shots out of its NB-13L battery, while the HX99 can take 370 images on a single charge of its NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. 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. The HX99 was launched at a somewhat lower price (by 15 percent) than the G9X, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G9 X features an one-inch sensor and the Sony HX99 a 1/2.3-inch sensor. The sensor area in the HX99 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the G9X has a native 3:2 aspect ratio, while the one in the HX99 offers a 4:3 aspect.
With 20MP, the G9X offers a higher resolution than the HX99 (18MP), but the G9X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.25μm for the HX99) due to its larger sensor. However, the HX99 is a much more recent model (by 2 years and 10 months) than the G9X, 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 HX99 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon G9 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Sony HX99 are 24.5 x 18.4 inches or 62.2 x 46.6 cm for good quality, 19.6 x 14.7 inches or 49.7 x 37.3 cm for very good quality, and 16.3 x 12.2 inches or 41.5 x 31.1 cm for excellent quality prints.
The Canon PowerShot G9 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Sony Cyber-shot DSC-HX99 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
In terms of underlying technology, the G9X is build around a BSI-CMOS sensor, while the HX99 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 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 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the HX99 provides a better video resolution than the G9X. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the HX99 has an electronic viewfinder (638k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon G9 X, the Sony HX99, and comparable cameras.

The Canon G9 X 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.
Both the G9X and the HX99 have zoom lenses built in. The G9X has a 28-84mm f/2.0-4.9 optic and the HX99 offers a 24-720mm f/3.5-6.4 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Canon. The G9X offers the faster maximum aperture.
The G9X writes its imaging data to SDXC cards, while the HX99 uses SDXC or Memory Stick PRO Duo 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 and Sony Cyber-shot DSC-HX99 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The HX99 is a recent model that features in the current product line-up of Sony. In contrast, the G9X has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the G9X was succeeded by the Canon G9 X Mark II. Further information on the features and operation of the G9X and HX99 can be found, respectively, in the Canon G9 X Manual (free pdf) or the online Sony HX99 Manual.
So what is the bottom line? Is the Canon G9 X better than the Sony HX99 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon PowerShot G9 X:
- More detail: Offers more megapixels (20 vs 18MP) with a 7% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/3.5).
- Less heavy: Is lighter (by 33g or 14 percent) and hence easier to carry around.
- More heavily discounted: Has been available for much longer (launched in October 2015).
Arguments in favor of the Sony Cyber-shot DSC-HX99:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
- Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Longer lasting: Gets more shots (370 versus 220) out of a single battery charge.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was released into a lower priced segment (15 percent cheaper at launch).
- More modern: Reflects 2 years and 10 months of technical progress since the G9X launch.
If the count of relative strengths (bullet points above) is taken as a measure, the HX99 comes out slightly ahead of the G9X (12 : 11 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 Canon G9 X and the Sony HX99 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G9X and the HX99 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 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 ratings are only valid when referring to cameras in the same category and of the same age. 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.
