Canon G15 vs Panasonic G2
The Canon PowerShot G15 and the Panasonic Lumix DMC-G2 are two digital cameras that were officially introduced, respectively, in September 2012 and March 2010. The G15 is a fixed lens compact, while the G2 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (G15) and a Four Thirds (G2) sensor. Both cameras offer a resolution of 12 megapixels.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G15 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.
The physical size and weight of the Canon G15 and the Panasonic G2 are illustrated in the side-by-side display below. 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 size dimensions are rounded to the nearest millimeter.
The G2 can be obtained in three different colors (black, blue, red), while the G15 is only available in black.
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 (28 percent) than the Canon G15. In this context, it is worth noting that neither the G15 nor the G2 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 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.

Any camera decision will naturally be influenced heavily by the price. 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. The G15 was launched at a lower price than the G2, despite having a lens built in. 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.
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 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. 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 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 G2 a Four Thirds sensor. The sensor area in the G2 is 423 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 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.
Even though the G2 has a larger sensor, both cameras offer the same resolution of 12 megapixels. This implies that the G2 has a lower pixel density and larger individual pixels (with a pixel pitch of 4.33μm versus 1.89μm for the G15), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the G15 is much more recent (by 2 years and 6 months) than the G2, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The Canon PowerShot G15 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-G2 are ISO 100 to ISO 6400 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the G2 has a markedly higher DXO score than the G15 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 1.3 bits higher color depth, 1.2 EV of lower dynamic range, and 1.6 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.
|Panasonic G2||Four Thirds||12.0||4000||3000||720/30p||21.2||10.3||493||53|
|Panasonic G3||Four Thirds||15.8||4592||3448||1080/60i||21.0||10.6||667||56|
|Panasonic GF3||Four Thirds||12.0||4000||3000||1080/60i||20.6||10.0||458||49|

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G15 provides a higher video resolution than the G2. It can shoot video footage at 1080/24p, while the Panasonic is limited to 720/30p.
Beyond 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 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 adjacent table lists some of the other core features of the Canon G15 and Panasonic G2 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G2 has a touchscreen, while the G15 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G2 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the G15 does not have a selfie-screen.
Concerning the storage of imaging data, both the G15 and the G2 write their files to SDXC cards.
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 G15 and Panasonic Lumix DMC-G2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G15 and the G2 have been discontinued, but can regularly be found used on eBay. The G2 was replaced by the Panasonic G3, while the G15 was followed by the Canon G16. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So how do things add up? Which of the two cameras – the Canon G15 or the Panasonic G2 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon PowerShot G15:
- More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
- 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.
- More compact: Is smaller (107x76mm vs 124x84mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the G2).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 2 years and 6 months of technical progress since the G2 launch.
Arguments in favor of the Panasonic Lumix DMC-G2:
- Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
- Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
- 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.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (2.6 vs 2.1 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- More heavily discounted: Has been around for much longer (launched in March 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 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 incomplete and does no justice, for example, to the way the G15 or the G2 perform in practice. 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
