Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX20 IS and the Panasonic Lumix DC-FZ82? 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 SX20 and the Panasonic FZ82 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 size dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic FZ82 is notably larger (13 percent) than the Canon SX20. Moreover, the FZ82 is slightly heavier (3 percent) than the SX20. In this context, it is worth noting that neither the SX20 nor the FZ82 are weather-sealed.

The power pack in the FZ82 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The two cameras under review were launched at the same price and fall into the same market segment. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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.

While the two cameras under review share the same sensor size, the FZ82 offers a higher resolution of 18 megapixels, compared with 12 MP of the SX20. This megapixels advantage translates into a 22 percent gain in linear resolution. On the other hand, these sensor specs imply that the FZ82 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.25μm versus 1.53μm for the SX20). However, it should be noted that the FZ82 is much more recent (by 7 years and 4 months) than the SX20, 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 FZ82 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the FZ82 for good quality output (200 dots per inch) amounts to 24.5 x 18.4 inches or 62.2 x 46.6 cm, for very good quality (250 dpi) 19.6 x 14.7 inches or 49.7 x 37.3 cm, and for excellent quality (300 dpi) 16.3 x 12.2 inches or 41.5 x 31.1 cm. The corresponding values for the Canon SX20 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot SX20 IS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DC-FZ82 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.

In terms of underlying technology, the SX20 is build around a CCD sensor, while the FZ82 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the FZ82 provides a better video resolution than the SX20. It can shoot movie footage at 4K/30p, while the Canon is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the FZ82 offers a substantially higher resolution than the one in the SX20 (1166k vs 202k dots). The table below summarizes some of the other core capabilities of the Canon SX20 and Panasonic FZ82 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 FZ82 has a touchscreen, while the SX20 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 FZ82 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 SX20 and the FZ82 have zoom lenses built in. The SX20 has a 28-560mm f/2.8-5.7 optic and the FZ82 offers a 20-1200mm f/2.8-5.9 (focal lengths in full frame equivalent terms). Hence, the Panasonic provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Canon. Both cameras offer the same maximum aperture.

The SX20 writes its imaging data to SDHC cards, while the FZ82 uses SDXC cards. The FZ82 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX20 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 SX20 IS and Panasonic Lumix DC-FZ82 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the FZ82 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the SX20 does not provide wifi capability.

The FZ82 is a recent model that features in the current product line-up of Panasonic. In contrast, the SX20 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the SX20 was succeeded by the Canon SX30. Further information on the features and operation of the SX20 and FZ82 can be found, respectively, in the Canon SX20 Manual (free pdf) or the online Panasonic FZ82 Manual.

Review summary

So how do things add up? Is the Canon SX20 better than the Panasonic FZ82 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot SX20 IS:

• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
• More compact: Is smaller (123x88mm vs 130x94mm) and thus needs less room in the bag.
• More heavily discounted: Has been available for much longer (launched in August 2009).

Reasons to prefer the Panasonic Lumix DC-FZ82:

• More detail: Has more megapixels (18 vs 12MP), which boosts linear resolution by 22%.
• Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (1166k vs 202k dots).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (10 vs 0.7 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 7 years and 4 months of technical progress since the SX20 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the FZ82 is the clear winner of the contest (14 : 4 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 SX20 and the Panasonic FZ82 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 says little about, for example, the shooting experience and imaging performance of the SX20 and the FZ82 in practical situations. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
