Canon G7 X Mark III vs SX530
The Canon PowerShot G7 X Mark III and the Canon PowerShot SX530 HS are two digital cameras that were announced, respectively, in July 2019 and January 2015. Both the G7X Mark III and the SX530 are fixed lens compact cameras that are based on an one-inch (G7X Mark III) and a 1/2.3-inch (SX530) sensor. The G7X Mark III has a resolution of 20 megapixels, whereas the SX530 provides 15.9 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 Mark III and the Canon PowerShot SX530 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.
An illustration of the physical size and weight of the Canon G7 X Mark III and the Canon SX530 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The G7X Mark III can be obtained in two different colors (black, silver), while the SX530 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 Canon SX530 is considerably larger (54 percent) than the Canon G7 X Mark III. Moreover, the SX530 is substantially heavier (45 percent) than the G7X Mark III. In this context, it is worth noting that neither the G7X Mark III nor the SX530 are weather-sealed.
Concerning battery life, the G7X Mark III gets 235 shots out of its NB-13L battery, while the SX530 can take 210 images on a single charge of its NB-6LH power pack. The power pack in the G7X Mark III can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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 SX530 was launched at a markedly lower price (by 43 percent) than the G7X Mark III, 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.
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. 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 Mark III features an one-inch sensor and the Canon SX530 a 1/2.3-inch sensor. The sensor area in the SX530 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 Mark III has a native 3:2 aspect ratio, while the one in the SX530 offers a 4:3 aspect.
In terms of chip-set technology, the G7X Mark III uses a more advanced image processing engine (DIGIC 8) than the SX530 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
With 20MP, the G7X Mark III offers a higher resolution than the SX530 (15.9MP), but the G7X Mark III nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.33μm for the SX530) due to its larger sensor. Moreover, the G7X Mark III is a much more recent model (by 4 years and 6 months) than the SX530, 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 SX530 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon G7 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark III 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 SX530 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The Canon PowerShot G7 X Mark III 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 SX530 HS are ISO 100 to ISO 3200 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

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, but the G7X Mark III provides a higher video resolution than the SX530. It can shoot video footage at 4K/30p, while the SX530 is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The G7X Mark III and the SX530 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 Mark III and Canon SX530 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 Mark III has a touchscreen, while the SX530 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G7X Mark III 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 SX530 does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the G7X Mark III is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Canon G7 X Mark III 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 Mark III and the SX530 have zoom lenses built in. The G7X Mark III has a 24-100mm f/1.8-2.8 optic and the SX530 offers a 24-1200mm f/3.4-6.5 (focal lengths in full frame equivalent terms). Hence, the G7X Mark III and SX530 provide the same view at the wide-angle end, but the SX530 has more tele-photo reach at the long end. The G7X Mark III offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X Mark III and the SX530 write their files to SDXC cards. The G7X Mark III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX530 cannot take advantage of Ultra High Speed SD 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 G7 X Mark III and Canon PowerShot SX530 HS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark III has a microphone port, which is missing on the SX530. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The G7X Mark III is a recent model that features in the current product line-up of Canon. In contrast, the SX530 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the SX530 was succeeded by the Canon SX540. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

If the count of relative strengths (bullet points above) is taken as a measure, the G7X Mark III is the clear winner of the match-up (25 : 5 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

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 Mark III or the SX530 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], 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.
