Canon SX730 vs Panasonic ZS70
The Canon PowerShot SX730 HS and the Panasonic Lumix DC-ZS70 (labelled Panasonic TZ90 in some countries) are two digital cameras that were announced in April 2017. Both the SX730 and the ZS70 are fixed lens compact cameras that are equipped with a 1/2.3-inch sensor. Both cameras offer a resolution of 20.2 megapixels.
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 SX730 HS and the Panasonic Lumix DC-ZS70? 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 SX730 and the Panasonic ZS70 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.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic ZS70 is notably larger (7 percent) than the Canon SX730. Moreover, the ZS70 is markedly heavier (7 percent) than the SX730. In this context, it is worth noting that neither the SX730 nor the ZS70 are weather-sealed.
Concerning battery life, the SX730 gets 250 shots out of its NB-13L battery, while the ZS70 can take 380 images on a single charge of its DMW-BLG10 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The price is, of course, an important factor in any camera decision. 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 SX730 was launched at a somewhat lower price (by 11 percent) than the ZS70, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20.2 megapixels. This similarity in sensor specs implies that both the SX730 and the ZS70 have the same pixel density, as well as the same pixel size. Moreover, the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The Canon PowerShot SX730 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DC-ZS70 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
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 ZS70 provides a better video resolution than the SX730. 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 ZS70 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX730 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 SX730, the Panasonic ZS70, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The ZS70 has a touchscreen, while the SX730 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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 ZS70 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).
Both the SX730 and the ZS70 have zoom lenses built in. The SX730 has a 24-960mm f/3.3-6.9 optic and the ZS70 offers a 24-720mm f/3.3-6.4 (focal lengths in full frame equivalent terms). Hence, the Canon and Panasonic provide the same view at the wide-angle end, but the Panasonic has less tele-photo reach at the long end. Both cameras offer the same maximum aperture.
Concerning the storage of imaging data, both the SX730 and the ZS70 write their files to SDXC cards. The ZS70 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX730 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 SX730 HS and Panasonic Lumix DC-ZS70 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SX730 and the ZS70 have been discontinued, but can regularly be found used on eBay. The SX730 was replaced by the Canon SX730 HS, while the ZS70 was followed by the Panasonic ZS80. 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.
So what is the bottom line? Is the Canon SX730 better than the Panasonic ZS70 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot SX730 HS:
- Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More affordable: Was introduced into a lower priced segment (11 percent cheaper at launch).
Reasons to prefer the Panasonic Lumix DC-ZS70:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (10 vs 5.9 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Longer lasting: Gets more shots (380 versus 250) out of a single battery charge.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
If the number of relative strengths (bullet points above) is taken as a guide, the ZS70 emerges as the winner of the match-up (8 : 5 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.
How about other alternatives? Do the specifications of the Canon SX730 and the Panasonic ZS70 place the cameras among the top in their class? Find out in the latest Best Superzoom 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 incomplete and does no justice, for example, to the way the SX730 or the ZS70 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.
This is why expert reviews are important. 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.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
