Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX510 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.

Body comparison

The physical size and weight of the Canon SX510 and the Panasonic ZS70 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 width, height and depth dimensions are rounded to the nearest millimeter.

The ZS70 can be obtained in two different colors (black, silver), while the SX510 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 ZS70 is somewhat larger (3 percent) than the Canon SX510. However, the ZS70 is markedly lighter (8 percent) than the SX510. In this context, it is worth noting that neither the SX510 nor the ZS70 are weather-sealed.

Concerning battery life, the SX510 gets 250 shots out of its Canon NB-6LH battery, while the ZS70 can take 380 images on a single charge of its Panasonic DMW-BLG10 power pack. The power pack in the ZS70 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 SX510 was launched at a markedly lower price (by 45 percent) than the ZS70, 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.

Sensor comparison

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. 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 tend to be more expensive and 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.

While the two cameras under review share the same sensor size, the ZS70 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the SX510. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the ZS70 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.33μm for the SX510). However, it should be noted that the ZS70 is much more recent (by 3 years and 7 months) than the SX510, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. 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 resolution advantage of the Panasonic ZS70 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the ZS70 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 Canon SX510 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 SX510 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.

In terms of underlying technology, the SX510 is build around a CMOS sensor, while the ZS70 uses a BSI-CMOS imager. 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 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 can also record movies. 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 SX510. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range 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 SX510 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX510 and Panasonic ZS70 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The ZS70 has a touchscreen, while the SX510 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 SX510 and the ZS70 have zoom lenses built in. The SX510 has a 24-720mm f/3.4-5.8 optic and the ZS70 offers a 24-720mm f/3.3-6.4 (focal lengths in full frame equivalent terms). The ZS70 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX510 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 SX510 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 SX510 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 SX510 and the ZS70 have been discontinued, but can regularly be found used on ebay. The SX510 was replaced by the Canon SX520, while the ZS70 was followed by the Panasonic ZS80. Further information on the features and operation of the SX510 and ZS70 can be found, respectively, in the Canon SX510 Manual (free pdf) or the online Panasonic ZS70 Manual.

Review summary

So what conclusions can be drawn? Is the Canon SX510 better than the Panasonic ZS70 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon PowerShot SX510 HS:

• More affordable: Was introduced into a lower priced category (45 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in August 2013).

Arguments in favor of the Panasonic Lumix DC-ZS70:

• More detail: Has more megapixels (20.2 vs 15.9MP), which boosts linear resolution by 13%.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/24p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• 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: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/2000s vs 1/1600s) to freeze action.
• Faster burst: Shoots at higher frequency (10 vs 3.8 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/3.3 vs f/3.4).
• Longer lasting: Gets more shots (380 versus 250) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 3 years and 7 months of technical progress since the SX510 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the ZS70 is the clear winner of the contest (15 : 2 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 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.

How about other alternatives? Do the specifications of the Canon SX510 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 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 SX510 or the ZS70 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.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
