Canon 6D vs G15
The Canon EOS 6D and the Canon PowerShot G15 are two digital cameras that were revealed to the public in September 2012. The 6D is a DSLR, while the G15 is a fixed lens compact. The cameras are based on a full frame (6D) and a 1/1.7-inch (G15) sensor. The 6D has a resolution of 20 megapixels, whereas the G15 provides 12 MP.
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 EOS 6D and the Canon PowerShot G15? 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 side-by-side display below illustrates the physical size and weight of the Canon 6D and the Canon G15. 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 dimensions 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 Canon G15 is considerably smaller (49 percent) than the Canon 6D. It is worth mentioning in this context that the 6D is splash and dust resistant, 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 6D 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 6D and their specifications in the Canon EF Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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. The G15 was launched at a lower price than the 6D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. 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 6D features a full frame sensor and the Canon G15 a 1/1.7-inch sensor. The sensor area in the G15 is 95 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 4.6. The sensor in the 6D has a native 3:2 aspect ratio, while the one in the G15 offers a 4:3 aspect.
In terms of chip-set technology, the 6D uses a more advanced image processing engine (DIGIC 5+) than the G15 (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.
With 20MP, the 6D offers a higher resolution than the G15 (12MP), but the 6D nevertheless has larger individual pixels (pixel pitch of 6.57μm 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 Canon 6D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 6D for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 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 EOS 6D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon PowerShot G15 are ISO 80 to ISO 12800 (no boost).
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 6D provides substantially higher image quality than the G15, with an overall score that is 36 points higher. This advantage is based on 3.9 bits higher color depth, 0.6 EV in additional dynamic range, and 3.8 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 have a sensor with sufficiently fast read-out times for moving pictures, but the 6D provides a higher frame rate than the G15. It can shoot video footage at 1080/30p, while the G15 is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 6D and the G15 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The following table reports on some other key feature differences and similarities of the Canon 6D, the Canon G15, and comparable cameras.

One feature that is present on the 6D, but is missing on the G15 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
Concerning the storage of imaging data, both the 6D and the G15 write their files to SDXC cards. The 6D 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.
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 EOS 6D and Canon PowerShot G15 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 6D has a microphone port, which is missing on the G15. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Travel and landscape photographers will find it useful that the 6D has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the 6D and the G15 have been discontinued, but can regularly be found used on eBay. The 6D was replaced by the Canon 6D Mark II, 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 website.
So what conclusions can be drawn? Which of the two cameras – the Canon 6D or the Canon G15 – 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 EOS 6D:
- More detail: Offers more megapixels (20 vs 12MP) with a 32% higher linear resolution.
- Better image quality: Scores substantially higher (36 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (3.9 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (3.8 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC 5).
- Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Faster burst: Shoots at higher frequency (4.5 vs 2.1 flaps/sec) to capture the decisive moment.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (1090 versus 350) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Easier geotagging: Features an internal GPS sensor to log localization data.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
Arguments in favor of the Canon PowerShot G15:
- Ready to shoot: Comes with an integrated lens, while the 6D requires a separate lens.
- More compact: Is smaller (107x76mm vs 145x111mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the 6D).
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
If the count of individual advantages (bullet points above) is taken as a guide, the 6D is the clear winner of the match-up (17 : 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.
How about other alternatives? Do the specifications of the Canon 6D and the Canon G15 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 6D or the G15 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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. 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.
