Canon SX540 vs Panasonic G7
The Canon PowerShot SX540 HS and the Panasonic Lumix DMC-G7 are two digital cameras that were revealed to the public, respectively, in January 2016 and May 2015. The SX540 is a fixed lens compact, while the G7 is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (SX540) and a Four Thirds (G7) sensor. The Canon has a resolution of 20.2 megapixels, whereas the Panasonic provides 15.8 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 SX540 HS and the Panasonic Lumix DMC-G7? 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 SX540 and the Panasonic G7 are illustrated 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 measures are rounded to the nearest millimeter.
The G7 can be obtained in two different colors (black, silver), while the SX540 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 Panasonic G7 is notably larger (9 percent) than the Canon SX540. In this context, it is worth noting that neither the SX540 nor the G7 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX540 has a lens built in, whereas the G7 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the G7 and their specifications in the Micro Four Thirds Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The SX540 was launched at a lower price than the G7, despite having a lens built in. 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. 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon SX540 features a 1/2.3-inch sensor and the Panasonic G7 a Four Thirds sensor. The sensor area in the G7 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
Despite having a smaller sensor, the Canon SX540 offers a higher resolution of 20.2 megapixels, compared with 15.8 MP of the Panasonic G7. 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 3.77μm for the G7). However, it should be noted that the SX540 is a somewhat more recent model (by 7 months) than the G7, 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 resolution advantage of the Canon SX540 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX540 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Panasonic G7 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.
The Canon PowerShot SX540 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DMC-G7 are ISO 160 to ISO 25600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7 provides a better video resolution than the SX540. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G7 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX540 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon SX540, the Panasonic G7, and comparable cameras.
|5.||Canon G1 X Mark III||2360||n||3.0||1040||swivel||Y||1/2000s||9.0||Y||Y|
|6.||Canon G9 X Mark II||none||n||3.0||1040||fixed||Y||1/2000s||8.2||Y||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7 has a touchscreen, while the SX540 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G7 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the SX540 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 G7 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 Panasonic G7 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.
Concerning the storage of imaging data, both the SX540 and the G7 write their files to SDXC cards. The G7 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the SX540 can use UHS-I cards (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 SX540 HS and Panasonic Lumix DMC-G7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|6.||Canon G9 X Mark II||-||stereo||mono||-||-||micro||2.0||Y||Y||Y|
It is notable that the G7 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The SX540 does not feature such a mic input.
The SX540 is a recent model that features in the current product line-up of Canon. In contrast, the G7 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G7 was succeeded by the Panasonic G85. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.

If the count of individual advantages (bullet points above) is taken as a guide, the G7 is the clear winner of the contest (21 : 7 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX540 or the G7. 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 why hands-on reviews by experts 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], 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
