Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 6D and the Canon PowerShot G12? 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 6D and the Canon G12. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G12 is considerably smaller (47 percent) than the Canon 6D. It is worth mentioning in this context that the 6D is splash and dust resistant, while the G12 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G12 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.

Concerning battery life, the 6D gets 1090 shots out of its Canon LP-E6 battery, while the G12 can take 370 images on a single charge of its Canon NB-7L power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G12 was launched at a lower price than the 6D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 6D features a full frame sensor and the Canon G12 a 1/1.7-inch sensor. The sensor area in the G12 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 G12 offers a 4:3 aspect.

In terms of chip-set technology, the 6D uses a more advanced image processing engine (DIGIC 5+) than the G12 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

With 20MP, the 6D offers a higher resolution than the G12 (10MP), but the 6D nevertheless has larger individual pixels (pixel pitch of 6.57μm versus 2.07μm for the G12) due to its larger sensor. Moreover, the 6D is a much more recent model (by 2 years) than the G12, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

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 G12 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 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 G12 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

In terms of underlying technology, the 6D is build around a CMOS sensor, while the G12 uses a CCD imager. 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 is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 6D provides substantially higher image quality than the G12, with an overall score that is 35 points higher. This advantage is based on 3.4 bits higher color depth, 0.9 EV in additional dynamic range, and 3.9 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 6D provides a higher video resolution than the G12. It can shoot video footage at 1080/30p, while the G12 is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 6D and the G12 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 table below summarizes some of the other core capabilities of the Canon 6D and Canon G12 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 6D, but is missing on the G12 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 G12 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 G12 cannot take advantage of Ultra High Speed SD 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 EOS 6D and Canon PowerShot G12 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 G12. 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 G12 have been discontinued, but can regularly be found used on ebay. The G12 was replaced by the Canon G15, while the 6D was followed by the Canon 6D Mark II. Further information on the features and operation of the 6D and G12 can be found, respectively, in the Canon 6D Manual (free pdf) or the online Canon G12 Manual.

Review summary

So how do things add up? Is the Canon 6D better than the Canon G12 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS 6D:

• More detail: Offers more megapixels (20 vs 10MP) with a 44% higher linear resolution.
• Better image quality: Scores substantially higher (35 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (3.4 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (3.9 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC 4).
• Better video: Provides higher definition movie capture (1080/30p vs 720/24p).
• 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.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 461k dots).
• Faster burst: Shoots at higher frequency (4.5 vs 1.1 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 370) 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.
• More modern: Reflects 2 years of technical progress since the G12 launch.

Advantages of the Canon PowerShot G12:

• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Ready to shoot: Comes with an integrated lens, while the 6D requires a separate lens.
• More compact: Is smaller (112x76mm 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.
• More heavily discounted: Has been around for much longer (launched in September 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the 6D is the clear winner of the match-up (19 : 8 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 G12 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 G12 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.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

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