Canon G1 X vs G15
The Canon PowerShot G1 X and the Canon PowerShot G15 are two digital cameras that were officially introduced, respectively, in January 2012 and September 2012. Both the G1X and the G15 are fixed lens compact cameras that are based on an 1.5-inch (G1X) and a 1/1.7-inch (G15) sensor. The G1X has a resolution of 14.2 megapixels, whereas the G15 provides 12 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 G1 X and the Canon PowerShot G15? 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.
The side-by-side display below illustrates the physical size and weight of the Canon G1 X and the Canon G15. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G15 is notably smaller (14 percent) than the Canon G1 X. Moreover, the G15 is markedly lighter (34 percent) than the G1X. In this context, it is worth noting that neither the G1X nor the G15 are weather-sealed.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 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 G15 was launched at a markedly lower price (by 38 percent) than the G1X, 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.
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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G1 X features an 1.5-inch sensor and the Canon G15 a 1/1.7-inch sensor. The sensor area in the G15 is 84 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 4.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
With 14.2MP, the G1X offers a higher resolution than the G15 (12MP), but the G1X nevertheless has larger individual pixels (pixel pitch of 4.30μm versus 1.89μm for the G15) due to its larger sensor. However, the G15 is a somewhat more recent model (by 8 months) than the G1X, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon G1 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X for good quality output (200 dots per inch) amounts to 21.8 x 16.3 inches or 55.3 x 41.5 cm, for very good quality (250 dpi) 17.4 x 13.1 inches or 44.2 x 33.2 cm, and for excellent quality (300 dpi) 14.5 x 10.9 inches or 36.8 x 27.6 cm. The corresponding values for the Canon G15 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Canon PowerShot G1 X has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Canon PowerShot G15 are ISO 80 to ISO 12800 (no boost).
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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the G1X provides substantially higher image quality than the G15, with an overall score that is 14 points higher. This advantage is based on 1.8 bits higher color depth, 0.7 EV of lower dynamic range, and 2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
|1.||Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|

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 (1080/24p).
Apart from body and sensor, cameras can and do differ across a range of features. The G1X and the G15 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The following table reports on some other key feature differences and similarities of the Canon G1 X, the Canon G15, and comparable cameras.

Both the G1X and the G15 have zoom lenses built in. The G1X has a 28-112mm f/2.8-5.8 optic and the G15 offers a 28-140mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the G1X and G15 provide the same view at the wide-angle end, but the G15 has more tele-photo reach at the long end. The G15 offers the faster maximum aperture.
Concerning the storage of imaging data, both the G1X and the G15 write their files to SDXC cards.
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 G1 X and Canon PowerShot G15 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G1X and the G15 have been discontinued, but can regularly be found used on ebay. The G1X was replaced by the Canon G1X Mark II, while the G15 was followed by the Canon G16. Further information on the features and operation of the G1X and G15 can be found, respectively, in the Canon G1 X Manual (free pdf) or the online Canon G15 Manual.
So what conclusions can be drawn? Which of the two cameras – the Canon G1 X or the Canon G15 – 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.
Reasons to prefer the Canon PowerShot G1 X:
- More detail: Offers more megapixels (14.2 vs 12MP) with a 9% higher linear resolution.
- Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.8 bits more color depth).
- Better low-light sensitivity: Requires less light for good images (2 stops ISO advantage).
- 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.
- More heavily discounted: Has been on the market for longer (launched in January 2012).
Arguments in favor of the Canon PowerShot G15:
- More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- More compact: Is smaller (107x76mm vs 117x81mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 182g or 34 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (350 versus 250) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- More modern: Was introduced somewhat (8 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the G15 comes out slightly ahead of the G1X (8 : 7 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 G1 X and the Canon G15 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G1X or the G15. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
