Any camera decision will naturally be influenced heavily by the price. 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 HX90V was launched at a markedly lower price (by 57 percent) than the G3X, which puts it into a different market segment. 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 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 G3 X features an one-inch sensor and the Sony HX90V a 1/2.3-inch sensor. The sensor area in the HX90V 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 G3X has a native 3:2 aspect ratio, while the one in the HX90V offers a 4:3 aspect.

With 20MP, the G3X offers a higher resolution than the HX90V (18MP), but the G3X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.25μm for the HX90V) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the HX90V has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon G3 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G3X 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 HX90V 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 G3 X has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-HX90V are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated 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 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. 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for 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. For example, the HX90V has an electronic viewfinder (638k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The table below summarizes some of the other core capabilities of the Canon G3 X and Sony HX90V in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G3X has a touchscreen, while the HX90V has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Both the G3X and the HX90V have zoom lenses built in. The G3X has a 24-600mm f/2.8-5.6 optic and the HX90V offers a 24-720mm f/3.5-6.4 (focal lengths in full frame equivalent terms). Hence, the Canon and Sony provide the same view at the wide-angle end, but the Sony has more tele-photo reach at the long end. The G3X offers the faster maximum aperture.

The G3X writes its imaging data to SDXC cards, while the HX90V 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.

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 PowerShot G3 X and Sony Cyber-shot DSC-HX90V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G3X has a hotshoe, while the HX90V does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Travel and landscape photographers will find it useful that the HX90V has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the G3X and the HX90V have been discontinued, but can regularly be found used on ebay. The HX90V was replaced by the Sony HX99, while the G3X does not have a direct successor. Further information on the features and operation of the G3X and HX90V can be found, respectively, in the Canon G3 X Manual (free pdf) or the online Sony HX90V Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon G3 X or the Sony HX90V – 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 G3 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.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1620k vs 921k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.5).
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.

Reasons to prefer the Sony Cyber-shot DSC-HX90V:

• 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.
• Faster burst: Shoots at higher frequency (10 vs 5.9 flaps/sec) to capture the decisive moment.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More compact: Is smaller (102x58mm vs 123x77mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 488g or 67 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (360 versus 300) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).

If the count of individual advantages (bullet points above) is taken as a guide, the G3X is the clear winner of the match-up (14 : 10 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 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 G3 X and the Sony HX90V place the cameras among the top in their class? Find out in the latest Best Superzoom 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G3X or the HX90V. 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 following table reports the overall ratings of the cameras as published by some of the major 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 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.
