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 two cameras under review were launched at the same price and fall into the same 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 G15 features a 1/1.7-inch sensor and the Panasonic FZ100 a 1/2.3-inch sensor. The sensor area in the FZ100 is 35 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the FZ100 offers a higher resolution of 14 megapixels, compared with 12 MP of the G15. 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 1.41μm versus 1.89μm for the G15). Moreover, it should be noted that the G15 is much more recent (by 2 years and 1 month) than the FZ100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the FZ100 has no anti-alias filter installed, so that it can capture all the detail its 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 G15 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 G15 has a native sensitivity range from ISO 80 to ISO 12800. 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the FZ100 provides a faster frame rate than the G15. It can shoot movie footage at 1080/60i, 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 FZ100 has an electronic viewfinder (202k dots), while the G15 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The following table reports on some other key feature differences and similarities of the Canon G15, the Panasonic FZ100, and comparable cameras.

Both the G15 and the FZ100 have zoom lenses built in. The G15 has a 28-140mm f/1.8-2.8 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. The G15 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G15 and the FZ100 write their files to SDXC cards.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G15 or the Panasonic FZ100 – 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 G15:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
• More compact: Is smaller (107x76mm vs 124x82mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 188g or 35 percent) and hence easier to carry around.
• More modern: Reflects 2 years and 1 month of technical progress since the FZ100 launch.

Arguments in favor of the Panasonic Lumix DMC-FZ100:

• More detail: Has more megapixels (14 vs 12MP), which boosts linear resolution by 8%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher movie framerates (1080/60i versus 1080/24p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (11 vs 2.1 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.
• Longer lasting: Gets more shots (410 versus 350) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in July 2010).

If the count of individual advantages (bullet points above) is taken as a guide, the G15 comes out slightly ahead of the FZ100 (12 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 G15 and the Panasonic FZ100 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings 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 says little about, for example, the shooting experience and imaging performance of the G15 and the FZ100 in practical situations. 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 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.

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.
