Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X and the Panasonic Lumix DMC-FZ150? 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 G1 X and the Panasonic FZ150 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 measures 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 FZ150 is notably larger (7 percent) than the Canon G1 X. However, the FZ150 is slightly lighter (1 percent) than the G1X. In this context, it is worth noting that neither the G1X nor the FZ150 are weather-sealed.

Concerning battery life, the G1X gets 250 shots out of its Canon NB-10L battery, while the FZ150 can take 410 images on a single charge of its Panasonic DMW-BMB9 power pack.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The FZ150 was launched at a markedly lower price (by 38 percent) than the G1X, 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 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 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

Of the two cameras under consideration, the Canon G1 X features an 1.5-inch sensor and the Panasonic FZ150 a 1/2.3-inch sensor. The sensor area in the FZ150 is 89 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

With 14.2MP, the G1X offers a higher resolution than the FZ150 (12MP), but the G1X nevertheless has larger individual pixels (pixel pitch of 4.30μm versus 1.53μm for the FZ150) due to its larger sensor. Moreover, the G1X is a somewhat more recent model (by 4 months) than the FZ150, and its sensor might 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 FZ150 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon G1 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X for good quality output (200 dots per inch) amounts to 21.8 x 16.3 inches or 55.3 x 41.5 cm, for very good quality (250 dpi) 17.4 x 13.1 inches or 44.2 x 33.2 cm, and for excellent quality (300 dpi) 14.5 x 10.9 inches or 36.8 x 27.6 cm. The corresponding values for the Panasonic FZ150 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 G1 X has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-FZ150 are ISO 100 to ISO 3200, 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 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. Of the two cameras under review, the G1X provides substantially higher image quality than the FZ150, with an overall score that is 20 points higher. This advantage is based on 2.3 bits higher color depth, 0.1 EV of lower dynamic range, and 2.3 stops in additional low light sensitivity. 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, but the FZ150 provides a faster frame rate than the G1X. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the FZ150 has an electronic viewfinder (202k dots), while the G1X 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 G1 X, the Panasonic FZ150, and comparable cameras.

Both the G1X and the FZ150 have zoom lenses built in. The G1X has a 28-112mm f/2.8-5.8 optic and the FZ150 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.

Concerning the storage of imaging data, both the G1X and the FZ150 write their files to SDXC 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 G1 X and Panasonic Lumix DMC-FZ150 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G1X and the FZ150 have been discontinued, but can regularly be found used on ebay. The FZ150 was replaced by the Panasonic FZ200, while the G1X was followed by the Canon G1X Mark II. Further information on the features and operation of the G1X and FZ150 can be found, respectively, in the Canon G1 X Manual (free pdf) or the online Panasonic FZ150 Manual.

Review summary

So how do things add up? Is the Canon G1 X better than the Panasonic FZ150 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot G1 X:

• More detail: Offers more megapixels (14.2 vs 12MP) with a 9% higher linear resolution.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Scores substantially higher (20 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.3 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (2.3 stops ISO advantage).
• 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.
• More modern: Is somewhat more recent (announced 4 months after the FZ150).

Reasons to prefer the Panasonic Lumix DMC-FZ150:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• Faster burst: Shoots at higher frequency (12 vs 1.9 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 250) out of a single battery charge.
• More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in August 2011).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (9 points each). 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 G1 X and the Panasonic FZ150 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 G1X and the FZ150 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 hands-on reviews by experts 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.

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

The above review scores should be interpreted 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
