Canon 6D vs G7X
The Canon EOS 6D and the Canon PowerShot G7 X are two digital cameras that were announced, respectively, in September 2012 and September 2014. The 6D is a DSLR, while the G7X is a fixed lens compact. The cameras are based on a full frame (6D) and an one-inch (G7X) sensor. Both cameras offer a resolution of 20 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 EOS 6D and the Canon PowerShot G7 X? 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.
An illustration of the physical size and weight of the Canon 6D and the Canon G7 X 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 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 G7 X is considerably smaller (62 percent) than the Canon 6D. It is worth mentioning in this context that the 6D is splash and dust resistant, while the G7X does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X 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 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 G7X 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.
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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 6D features a full frame sensor and the Canon G7 X an one-inch sensor. The sensor area in the G7X is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the G7X uses a more advanced image processing engine (DIGIC 6) than the 6D (DIGIC 5+), with benefits for noise reduction, color accuracy, and processing speed.
Even though the 6D has a larger sensor, both cameras offer the same resolution of 20 megapixels. This implies that the 6D has a lower pixel density and larger individual pixels (with a pixel pitch of 6.57μm versus 2.41μm for the G7X), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the G7X is a somewhat more recent model (by 1 year and 11 months) than the 6D, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
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 G7 X are ISO 125 to ISO 12800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 G7X, with an overall score that is 11 points higher. This advantage is based on 0.8 bits higher color depth, 0.6 EV of lower dynamic range, and 2.1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G7X provides a faster frame rate than the 6D. It can shoot movie footage at 1080/60p, while the 6D is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 6D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G7X relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon 6D and Canon G7 X along with similar information for a selection of comparators.

One feature that is present on the 6D, but is missing on the G7X 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.The G7X 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 6D does not have a selfie-screen.
The Canon G7 X 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 6D and the G7X write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 G7 X 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 hotshoe, while the G7X does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
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 G7X have been discontinued, but can regularly be found used on eBay. The 6D was replaced by the Canon 6D Mark II, while the G7X was followed by the Canon G7 X Mark II. 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 how do things add up? Is there a clear favorite between the Canon 6D and the Canon G7 X? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 6D:
- Better image quality: Scores substantially higher (11 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (2.1 stops ISO advantage).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- Longer lasting: Can take more shots (1090 versus 210) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Easier geotagging: Features an internal GPS sensor to log localization data.
- More heavily discounted: Has been on the market for longer (launched in September 2012).
Arguments in favor of the Canon PowerShot G7 X:
- More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
- Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 5+).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.

- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with an integrated lens, while the 6D requires a separate lens.
- More compact: Is smaller (103x60mm 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.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Was introduced somewhat (1 year and 11 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the G7X is the clear winner of the contest (16 : 12 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.
How about other alternatives? Do the specifications of the Canon 6D and the Canon G7 X 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 says little about, for example, the shooting experience and imaging performance of the 6D and the G7X in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
