Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX20 IS and the Panasonic Lumix DMC-FZ100? 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 SX20 and the Panasonic FZ100. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic FZ100 is notably smaller (6 percent) than the Canon SX20. Moreover, the FZ100 is markedly lighter (10 percent) than the SX20. In this context, it is worth noting that neither the SX20 nor the FZ100 are weather-sealed.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 SX20 was launched at a somewhat lower price (by 20 percent) than the FZ100, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 tend to be associated with larger, more expensive camera bodies 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 FZ100 offers a higher resolution of 14 megapixels, compared with 12 MP of the SX20. This megapixels advantage translates into a 8 percent gain in linear resolution. On the other hand, these sensor specs imply that the FZ100 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.41μm versus 1.53μm for the SX20). However, it should be noted that the FZ100 is a somewhat more recent model (by 11 months) than the SX20, 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 resolution advantage of the Panasonic FZ100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the FZ100 for good quality output (200 dots per inch) amounts to 21.6 x 16.2 inches or 54.9 x 41.1 cm, for very good quality (250 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm, and for excellent quality (300 dpi) 14.4 x 10.8 inches or 36.6 x 27.4 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 DMC-FZ100 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-6400.

In terms of underlying technology, the SX20 is build around a CCD sensor, while the FZ100 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the FZ100 provides a better video resolution than the SX20. It can shoot movie footage at 1080/60i, 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 SX20 and the FZ100 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 202k dots. The following table reports on some other key feature differences and similarities of the Canon SX20, the Panasonic FZ100, and comparable cameras.

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

Both the SX20 and the FZ100 have zoom lenses built in. The SX20 has a 28-560mm f/2.8-5.7 optic and the FZ100 offers a 25-600mm f/2.8-5.2 (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 FZ100 uses SDXC cards.

Connectivity comparison

Review summary

So what is the bottom line? Is there a clear favorite between the Canon SX20 and the Panasonic FZ100? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon PowerShot SX20 IS:

• Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
• More affordable: Was introduced into a lower priced segment (20 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in August 2009).

Reasons to prefer the Panasonic Lumix DMC-FZ100:

• More detail: Has more megapixels (14 vs 12MP), which boosts linear resolution by 8%.
• Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
• 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 (460k vs 230k dots).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (11 vs 0.7 flaps/sec) to capture the decisive moment.
• 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.
• More modern: Was introduced somewhat (11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the FZ100 is the clear winner of the contest (9 : 3 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 FZ100 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 SX20 or the FZ100 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 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 (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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
