Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX420 IS 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

An illustration of the physical size and weight of the Canon SX420 and the Panasonic ZS70 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 SX420 can be obtained in two different colors (black, red), while the ZS70 is also available in two color-versions, but different ones (black, silver).

Comparison SX420 or ZS70 rear

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 (5 percent) than the Canon SX420. However, the ZS70 is slightly lighter (1 percent) than the SX420. In this context, it is worth noting that neither the SX420 nor the ZS70 are weather-sealed.

The power pack in the ZS70 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. 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 SX420 was launched at a markedly lower price (by 33 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 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.

Canon SX420 and Panasonic ZS70 sensor measures

While the two cameras under review share the same sensor size, the ZS70 offers a slightly higher resolution of 20.2 megapixels, compared with 19.9 MP of the SX420. This megapixels advantage translates into a 0.59999999999999 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 1.19μm for the SX420). However, it should be noted that the ZS70 is a somewhat more recent model (by 1 year and 3 months) than the SX420, and its sensor might have benefitted from technological advances during this time that at least partly 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 Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. 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.

SX420 versus ZS70 MP

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 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 SX420. It can shoot movie footage at 4K/30p, while the Canon is limited to 720/25p.

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 SX420 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX420 and Panasonic ZS70 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 ZS70 has a touchscreen, while the SX420 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The ZS70 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 SX420 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 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 SX420 and the ZS70 have zoom lenses built in. The SX420 has a 24-1008mm f/3.5-6.6 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. The ZS70 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX420 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 SX420 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 SX420 IS and Panasonic Lumix DC-ZS70 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The SX420 is a recent model that features in the current product line-up of Canon. In contrast, the ZS70 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the ZS70 was succeeded 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.

Review summary

So what is the bottom line? Which of the two cameras – the Canon SX420 or the Panasonic ZS70 – 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.

ilogo

Advantages of the Canon PowerShot SX420 IS:

  • Faster shutter: Has higher mechanical shutter speed (1/4000s 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.
  • More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2016).

ilogo

Arguments in favor of the Panasonic Lumix DC-ZS70:

  • Better video: Provides higher definition movie capture (4K/30p vs 720/25p).
  • Easier framing: Has an electronic viewfinder for image composition and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k 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 burst: Shoots at higher frequency (10 vs 0.5 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/3.5).
  • Longer lasting: Gets more shots (380 versus 195) 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: Was introduced somewhat (1 year and 3 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the ZS70 is the clear winner of the contest (12 : 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 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.

SX420 05:12 ZS70

How about other alternatives? Do the specifications of the Canon SX420 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the SX420 or the ZS70 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

The review scores listed above should be treated with care, 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.
