Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G5 X and the Canon PowerShot G12? 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 physical size and weight of the Canon G5 X and the Canon G12 are illustrated in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.

In this particular case, the Canon G5 X and the Canon G12 have exactly the same width and height, and, thus, have identically-sized bodies. However, the G12 is markedly heavier (14 percent) than the G5X. In this context, it is worth noting that neither the G5X nor the G12 are weather-sealed.

Concerning battery life, the G5X gets 210 shots out of its Canon NB-13L battery, while the G12 can take 370 images on a single charge of its Canon NB-7L power pack. The power pack in the G5X can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 G12 was launched at a markedly lower price (by 38 percent) than the G5X, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G5 X features an one-inch sensor and the Canon G12 a 1/1.7-inch sensor. The sensor area in the G12 is 63 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 4.6. The sensor in the G5X has a native 3:2 aspect ratio, while the one in the G12 offers a 4:3 aspect.

In terms of chip-set technology, the G5X uses a more advanced image processing engine (DIGIC 6) than the G12 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

With 20MP, the G5X offers a higher resolution than the G12 (10MP), but the G5X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 2.07μm for the G12) due to its larger sensor. Moreover, the G5X is a much more recent model (by 5 years) than the G12, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon G5 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G5X 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 Canon G12 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Canon PowerShot G5 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 Canon PowerShot G12 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

In terms of underlying technology, the G5X is build around a BSI-CMOS sensor, while the G12 uses a CCD 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the G5X provides substantially higher image quality than the G12, with an overall score that is 15 points higher. This advantage is based on 1 bits higher color depth, 1.1 EV in additional dynamic range, and 1.5 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 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 G5X provides a higher video resolution than the G12. It can shoot video footage at 1080/60p, while the G12 is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G5X has an electronic viewfinder (2360k dots), while the G12 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Canon G5 X and Canon G12 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G5X has a touchscreen, while the G12 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon G5 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 G5X and the G12 have zoom lenses built in. The G5X has a 24-100mm f/1.8-2.8 optic and the G12 offers a 28-140mm f/2.8-4.5 (focal lengths in full frame equivalent terms). Hence, the G5X provides a wider angle of view at the short end than the G12, but less tele-photo reach at the long end. The G5X offers the faster maximum aperture.

Concerning the storage of imaging data, both the G5X and the G12 write their files to SDXC cards. The G5X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G12 cannot take advantage of Ultra High Speed SD cards.

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 G5 X and Canon PowerShot G12 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G5X offers wifi support, while the G12 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the G5X and the G12 have been discontinued, but can regularly be found used on ebay. The G12 was replaced by the Canon G15, while the G5X was followed by the Canon G5 X Mark II. Further information on the features and operation of the G5X and G12 can be found, respectively, in the Canon G5 X Manual (free pdf) or the online Canon G12 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon G5 X or the Canon G12 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon PowerShot G5 X:

• More detail: Offers more megapixels (20 vs 10MP) with a 44% higher linear resolution.
• Better image quality: Scores substantially higher (15 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (1.1 EV of extra DR).

• Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 4).
• Better video: Provides higher definition movie capture (1080/60p vs 720/24p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 461k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (5.9 vs 1.1 flaps/sec) to capture the decisive moment.
• 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/1.8 vs f/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Less heavy: Is lighter (by 48g or 12 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.

Advantages of the Canon PowerShot G12:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (370 versus 210) out of a single battery charge.
• More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in September 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the G5X is the clear winner of the match-up (21 : 6 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 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 G5 X and the Canon G12 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 G5X or the G12 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 where reviews by experts come in. 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 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
