Body comparison

An illustration of the physical size and weight of the Canon G15 and the Panasonic GH3 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 size dimensions are rounded to the nearest millimeter.

Size Canon G15 vs Panasonic GH3
Compare G15 versus GH3 top
Comparison G15 or GH3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH3 is considerably larger (52 percent) than the Canon G15. It is noteworthy in this context that the GH3 is splash and dust-proof, while the G15 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 has a lens built in, whereas the GH3 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 GH3 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G15 gets 350 shots out of its Canon NB-10L battery, while the GH3 can take 540 images on a single charge of its Panasonic DMW-BLF19 power pack.

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

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 G15 was launched at a lower price than the GH3, despite having a lens built in. 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 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G15 features a 1/1.7-inch sensor and the Panasonic GH3 a Four Thirds sensor. The sensor area in the GH3 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.

Canon G15 and Panasonic GH3 sensor measures

With 15.9MP, the GH3 offers a higher resolution than the G15 (12MP), but the GH3 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.89μm for the G15) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

The resolution advantage of the Panasonic GH3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GH3 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 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-GH3 are ISO 200 to ISO 12800, with the possibility to increase the ISO range to 125-25600.

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.

G15 versus GH3 MP

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 GH3 offers substantially better image quality than the G15 (overall score 25 points higher). The advantage is based on 2.8 bits higher color depth, 0.9 EV in additional 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH3 has an electronic viewfinder (1746k 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 table below summarizes some of the other core capabilities of the Canon G15 and Panasonic GH3 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GH3 has a touchscreen, while the G15 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The GH3 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.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GH3 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic GH3 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the G15 and the GH3 write their files to SDXC cards. The GH3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G15 cannot take advantage of Ultra High Speed SD cards.

It is notable that the GH3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G15 does not provide wifi capability.

Studio photographers will appreciate that the Panasonic GH3 (unlike the G15) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the G15 and the GH3 have been discontinued, but can regularly be found used on ebay. The G15 was replaced by the Canon G16, while the GH3 was followed by the Panasonic GH4. Further information on the features and operation of the G15 and GH3 can be found, respectively, in the Canon G15 Manual (free pdf) or the online Panasonic GH3 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G15 or the Panasonic GH3 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Canon PowerShot G15:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More detailed LCD: Has a higher resolution rear screen (922k vs 614k dots).
  • Ready to shoot: Has a lens built-in, whereas the GH3 requires a separate lens.
  • More compact: Is smaller (107x76mm vs 133x93mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the GH3).
  • 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.

ilogo

Advantages of the Panasonic Lumix DMC-GH3:

  • More detail: Has more megapixels (15.9 vs 12MP), which boosts linear resolution by 15%.
  • Better image quality: Scores substantially higher (25 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.8 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.3 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • 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 (6 vs 2.1 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (540 versus 350) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.

If the count of relative strengths (bullet points above) is taken as a measure, the GH3 is the clear winner of the contest (21 : 7 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.

G15 07:21 GH3

How about other alternatives? Do the specifications of the Canon G15 and the Panasonic GH3 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G15 or the GH3. 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 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. Thus, a score needs to be put into the context of the launch date and the launch price 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
