Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X and the Panasonic Lumix DMC-G2? 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 G1 X and the Panasonic G2. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The G2 can be obtained in three different colors (black, blue, red), while the G1X is only available in black.

Size Canon G1 X vs Panasonic G2
Compare G1X versus G2 top
Comparison G1X or G2 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G2 is notably larger (10 percent) than the Canon G1 X. In this context, it is worth noting that neither the G1X nor the G2 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X has a lens built in, whereas the G2 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the G2 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G1X gets 250 shots out of its NB-10L battery, while the G2 can take 360 images on a single charge of its DMW-BLB13 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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 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 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 G2 a Four Thirds sensor. The sensor area in the G2 is 14 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon G1 X and Panasonic G2 sensor measures

With 14.2MP, the G1X offers a higher resolution than the G2 (12MP), but the G1X has marginally smaller individual pixels (pixel pitch of 4.30μm versus 4.33μm for the G2). However, the G1X is a somewhat more recent model (by 1 year and 10 months) than the G2, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

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 G2 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-G2 are ISO 100 to ISO 6400 (no boost).

G1X versus G2 MP

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. Of the two cameras under review, the G1X has a notably higher overall DXO score than the G2 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 0.5 EV in additional dynamic range, and 0.4 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G2 has an electronic viewfinder (1440k 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 table below summarizes some of the other core capabilities of the Canon G1 X and Panasonic G2 in connection with corresponding information for a sample of similar cameras.

Notes: *) 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 G2 has a touchscreen, while the G1X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

Concerning the storage of imaging data, both the G1X and the G2 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-G2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Review summary

So what conclusions can be drawn? Is the Canon G1 X better than the Panasonic G2 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

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 image quality: Scores markedly higher (7 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • Better video: Provides higher definition movie capture (1080/24p vs 720/30p).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 460k dots).
  • Ready to shoot: Has a lens built-in, whereas the G2 requires a separate lens.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More modern: Is somewhat more recent (announced 1 year and 10 months after the G2).

ilogo

Advantages of the Panasonic Lumix DMC-G2:

  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (2.6 vs 1.9 flaps/sec) to capture the decisive moment.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (360 versus 250) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in March 2010).

If the count of individual advantages (bullet points above) is taken as a guide, the G1X emerges as the winner of the contest (9 : 6 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.

G1X 09:06 G2

How about other alternatives? Do the specifications of the Canon G1 X and the Panasonic G2 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G1X or the G2. 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.

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

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
