Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX620 HS and the Panasonic Lumix DMC-ZS100? 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 side-by-side display below illustrates the physical size and weight of the Canon SX620 and the Panasonic ZS100. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The SX620 can be obtained in three different colors (black, silver, red), while the ZS100 is available in two color-versions (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic ZS100 is notably larger (30 percent) than the Canon SX620. Moreover, the ZS100 is substantially heavier (71 percent) than the SX620. In this context, it is worth noting that neither the SX620 nor the ZS100 are weather-sealed.

Concerning battery life, the SX620 gets 295 shots out of its Canon NB-13L battery, while the ZS100 can take 300 images on a single charge of its Panasonic DMW-BLG10 power pack. The power pack in the ZS100 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX620 was launched at a markedly lower price (by 60 percent) than the ZS100, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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.

Of the two cameras under consideration, the Canon SX620 features a 1/2.3-inch sensor and the Panasonic ZS100 an one-inch sensor. The sensor area in the ZS100 is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the SX620 has a native 4:3 aspect ratio, while the one in the ZS100 offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX620 offers a higher resolution of 20.2 megapixels, compared with 20 MP of the Panasonic ZS100. 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 2.41μm for the ZS100). However, it should be noted that the SX620 is a somewhat more recent model (by 4 months) than the ZS100, 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 SX620 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Canon PowerShot SX620 HS has a native sensitivity range from ISO 80 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DMC-ZS100 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

In terms of underlying technology, the SX620 is build around a BSI-CMOS sensor, while the ZS100 uses a 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the ZS100 provides a better video resolution than the SX620. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the ZS100 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX620 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon SX620 and Panasonic ZS100 in connection with corresponding information for a sample of similar cameras.

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 ZS100 has a touchscreen, while the SX620 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 ZS100 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 ZS100 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 SX620 and the ZS100 have zoom lenses built in. The SX620 has a 25-625mm f/3.2-6.6 optic and the ZS100 offers a 25-250mm f/2.8-5.9 (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 ZS100 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX620 and the ZS100 write their files to SDXC cards. The ZS100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX620 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 SX620 HS and Panasonic Lumix DMC-ZS100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SX620 and the ZS100 have been discontinued, but can regularly be found used on ebay. The ZS100 was replaced by the Panasonic ZS200, while the SX620 does not have a direct successor. Further information on the features and operation of the SX620 and ZS100 can be found, respectively, in the Canon SX620 Manual (free pdf) or the online Panasonic ZS100 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon SX620 or the Panasonic ZS100 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon PowerShot SX620 HS:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More compact: Is smaller (97x57mm vs 111x65mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 130g or 42 percent) and hence easier to carry around.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 4 months after the ZS100).

Advantages of the Panasonic Lumix DMC-ZS100:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• 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 2.5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/3.2).
• 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 heavily discounted: Has been on the market for longer (launched in January 2016).

If the count of individual advantages (bullet points above) is taken as a guide, the ZS100 is the clear winner of the contest (16 : 7 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 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 SX620 and the Panasonic ZS100 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 SX620 or the ZS100 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 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.

The review scores listed above should be treated 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 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.
