Canon G3 X vs Canon R6
The Canon PowerShot G3 X and the Canon EOS R6 are two digital cameras that were revealed to the public, respectively, in June 2015 and July 2020. The G3X is a fixed lens compact, while the Canon R6 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G3X) and a full frame (Canon R6) 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 PowerShot G3 X and the Canon EOS R6? 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 G3 X and the Canon R6 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon R6 is considerably larger (43 percent) than the Canon G3 X. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G3X has a lens built in, whereas the Canon R6 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
Concerning battery life, the G3X gets 300 shots out of its NB-10L battery, while the Canon R6 can take 360 images on a single charge of its LP-E6NH power pack. The power pack in the Canon R6 can be charged via the USB port, which can be very convenient when travelling.
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.

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 G3X was launched at a lower price than the Canon R6, 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 size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 G3 X features an one-inch sensor and the Canon R6 a full frame sensor. The sensor area in the Canon R6 is 645 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the Canon R6 uses a more advanced image processing engine (DIGIC X) than the G3X (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.
Even though the Canon R6 has a larger sensor, both cameras offer the same resolution of 20 megapixels. This implies that the Canon R6 has a lower pixel density and larger individual pixels (with a pixel pitch of 6.57μm versus 2.41μm for the G3X), which gives it a potential advantage in terms of light gathering capacity. In addition, the Canon R6 is much more recent (by 5 years) than the G3X, and its sensor will have benefitted from technological advances during this time.
The Canon R6 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G3 X has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Canon EOS R6 are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-204800.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the Canon R6 offers substantially better image quality than the G3X (overall score 27 points higher). The advantage is based on 2.8 bits higher color depth, 2 EV in additional dynamic range, and 2.7 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 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 Canon R6 provides a better video resolution than the G3X. It can shoot movie footage at 4k/60p, while the G3X is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Canon R6 has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The table below summarizes some of the other core capabilities of the Canon G3 X and Canon R6 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The G3X has one, while the Canon R6 does not. While the built-in flash of the G3X is not very powerful, it can at times be useful as a fill-in light.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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 Canon R6 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 Canon R6 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 G3X and the Canon R6 write their files to SDXC cards. The Canon R6 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G3X only has one slot. The Canon R6 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G3X can use UHS-I cards (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 PowerShot G3 X and Canon EOS R6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G3X and the Canon R6 are recent models that are part of the current product line-up. Neither of the two has a direct predecessor, so perhaps they will constitute the origins of new camera lines for Canon. 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 the Canon G3 X better than the Canon R6 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon PowerShot G3 X:

If the number of relative strengths (bullet points above) is taken as a guide, the Canon R6 is the clear winner of the contest (21 : 7 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 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 G3 X and the Canon R6 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G3X and the Canon R6 in practical situations. 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 why hands-on reviews by experts 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 review scores listed above should be treated 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 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.
