Canon G7 X vs SX540
The Canon PowerShot G7 X and the Canon PowerShot SX540 HS are two digital cameras that were officially introduced, respectively, in September 2014 and January 2016. Both the G7X and the SX540 are fixed lens compact cameras that are based on an one-inch (G7X) and a 1/2.3-inch (SX540) sensor. The G7X has a resolution of 20 megapixels, whereas the SX540 provides 20.2 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 G7 X and the Canon PowerShot SX540 HS? 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 physical size and weight of the Canon G7 X and the Canon SX540 are illustrated 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.

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 SX540 was launched at a markedly lower price (by 43 percent) than the G7X, 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 sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 G7 X features an one-inch sensor and the Canon SX540 a 1/2.3-inch sensor. The sensor area in the SX540 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 G7X has a native 3:2 aspect ratio, while the one in the SX540 offers a 4:3 aspect.
Despite having a smaller sensor, the SX540 offers a slightly higher resolution of 20.2 megapixels, compared with 20 MP of the G7X. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 2.41μm for the G7X). However, it should be noted that the SX540 is a somewhat more recent model (by 1 year and 3 months) than the G7X, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the SX540 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Canon PowerShot SX540 HS are ISO 80 to ISO 3200 (no boost).
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.
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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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).
Beyond body and sensor, cameras can and do differ across a range of features. The G7X and the SX540 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The adjacent table lists some of the other core features of the Canon G7 X and Canon SX540 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 G7X has a touchscreen, while the SX540 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G7X has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the SX540 does not have a selfie-screen.
The Canon G7 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 G7X and the SX540 have zoom lenses built in. The G7X has a 24-100mm f/1.8-2.8 optic and the SX540 offers a 24-1200mm f/3.4-6.5 (focal lengths in full frame equivalent terms). Hence, the G7X and SX540 provide the same view at the wide-angle end, but the SX540 has more tele-photo reach at the long end. The G7X offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X and the SX540 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 G7 X and Canon PowerShot SX540 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G7X and the SX540 have been discontinued, but can regularly be found used on ebay. The G7X was replaced by the Canon G7 X Mark II, while the SX540 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Which of the two cameras – the Canon G7 X or the Canon SX540 – 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 G7 X:
- 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 461k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- 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.
- 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/3.4).
- More compact: Is smaller (103x60mm vs 120x82mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 138g or 31 percent) and hence easier to carry around.
- More heavily discounted: Has been on the market for longer (launched in September 2014).
Arguments in favor of the Canon PowerShot SX540 HS:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 3 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the G7X is the clear winner of the match-up (14 : 4 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 G7 X and the Canon SX540 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 remains incomplete and does no justice, for example, to the way the G7X or the SX540 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. 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 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
