Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X Mark III and the Canon EOS R5? 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

An illustration of the physical size and weight of the Canon G1 X Mark III and the Canon R5 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

Comparison G1X Mark III or R5 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon R5 is considerably larger (51 percent) than the Canon G1 X Mark III. 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 G1X Mark III has a lens built in, whereas the R5 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 G1X Mark III gets 200 shots out of its NB-13L battery, while the R5 can take 320 images on a single charge of its LP-E6NH power pack. The power pack in the R5 can be charged via the USB port, which can be very convenient when travelling.

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

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G1X Mark III was launched at a lower price than the R5, 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.

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. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Canon R5 a full frame sensor. The sensor area in the R5 is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the R5 uses a more advanced image processing engine (DIGIC X) than the G1X Mark III (DIGIC 7), with benefits for noise reduction, color accuracy, and processing speed.

Canon G1 X Mark III and Canon R5 sensor measures

With 44.8MP, the R5 offers a higher resolution than the G1X Mark III (24MP), but the R5 nevertheless has larger individual pixels (pixel pitch of 4.39μm versus 3.72μm for the G1X Mark III) due to its larger sensor. Moreover, the R5 is a much more recent model (by 2 years and 8 months) than the G1X Mark III, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon R5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R5 for good quality output (200 dots per inch) amounts to 41 x 27.3 inches or 104 x 69.4 cm, for very good quality (250 dpi) 32.8 x 21.9 inches or 83.2 x 55.5 cm, and for excellent quality (300 dpi) 27.3 x 18.2 inches or 69.4 x 46.3 cm. The corresponding values for the Canon G1 X Mark III are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The Canon PowerShot G1 X Mark III has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Canon EOS R5 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-102400.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the R5 provides a better video resolution than the G1X Mark III. It can shoot movie footage at 8K/30p, while the G1X Mark III is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the R5 offers a substantially higher resolution than the one in the G1X Mark III (5760k vs 2360k dots).

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The G1X Mark III has one, while the R5 does not. While the built-in flash of the G1X Mark III 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 R5 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 G1 X Mark III and the Canon R5 both have 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.

The G1X Mark III writes its imaging data to SDXC cards, while the R5 uses CFexpress or SDXC cards. The R5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G1X Mark III only has one slot. The R5 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G1X Mark III can use UHS-I cards (up to 104 MB/s).

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 PowerShot G1 X Mark III and Canon EOS R5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the R5 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G1X Mark III does not feature such a mic input.

Studio photographers will appreciate that the Canon R5 (unlike the G1X Mark III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the G1X Mark III and the R5 are recent models that are part of the current product line-up. The G1X Mark III replaced the earlier Canon G1 X Mark II, while the R5 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon G1 X Mark III and the Canon R5? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon PowerShot G1 X Mark III:

  • Ready to shoot: Has a lens built-in, whereas the R5 requires a separate lens.
  • More compact: Is smaller (115x78mm vs 138x98mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the R5).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • 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 heavily discounted: Has been available for much longer (launched in October 2017).


Arguments in favor of the Canon EOS R5:

  • More detail: Has more megapixels (44.8 vs 24MP), which boosts linear resolution by 37%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Better jpgs: Has a more modern image processing engine (DIGIC X vs DIGIC 7).
  • Better video: Provides higher definition movie capture (8K/30p vs 1080/60p).
  • 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 detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 2360k dots).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (2100k vs 1040k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (320 versus 200) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 2.0).
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 2 years and 8 months of technical progress since the G1X Mark III launch.

If the count of relative strengths (bullet points above) is taken as a measure, the R5 is the clear winner of the contest (23 : 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 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.

G1X Mark III 07:23 R5

How about other alternatives? Do the specifications of the Canon G1 X Mark III and the Canon R5 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 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 G1X Mark III and the R5 in practical situations. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
