Canon G7 X Mark II vs YI M1

The Canon PowerShot G7 X Mark II and the YI M1 are two digital cameras that were revealed to the public, respectively, in February 2016 and September 2016. The G7X Mark II is a fixed lens compact, while the M1 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G7X Mark II) and a Four Thirds (M1) sensor. The Canon has a resolution of 20 megapixels, whereas the YI provides 20.2 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 PowerShot G7 X Mark II and the YI M1? 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 G7 X Mark II and the YI M1. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The M1 can be obtained in two different colors (black, silver), while the G7X Mark II is only available in black.

Compare G7X Mark II versus M1 top
Comparison G7X Mark II or M1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the YI M1 is notably larger (13 percent) than the Canon G7 X Mark II. In this context, it is worth noting that neither the G7X Mark II nor the M1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens built in, whereas the M1 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 M1 and their specifications in the Micro Four Thirds Lens Catalog.

The battery packs of both cameras can be charged via USB, 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.

(1) Number of images that can be taken on a full battery charge according to the CIPA-standard; (2) Official announcement.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G7 X Mark II features an one-inch sensor and the YI M1 a Four Thirds sensor. The sensor area in the M1 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the G7X Mark II has a native 3:2 aspect ratio, while the one in the M1 offers a 4:3 aspect.

Canon G7 X Mark II and YI M1 sensor measures

With 20.2MP, the M1 offers a higher resolution than the G7X Mark II (20MP), but the M1 nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the G7X Mark II) due to its larger sensor. Moreover, the M1 is a somewhat more recent model (by 7 months) than the G7X Mark II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The Canon PowerShot G7 X Mark II 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 YI M1 are ISO 100 to ISO 25600 (no boost).

G7X Mark II versus M1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 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 M1 provides a better video resolution than the G7X Mark II. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The G7X Mark II and the M1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The adjacent table lists some of the other core features of the Canon G7 X Mark II and YI M1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The G7X Mark II has one, while the M1 does not. While the built-in flash of the G7X Mark II is not very powerful, it can at times be useful as a fill-in light.

The G7X Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the M1 does not have a selfie-screen.

The Canon G7 X Mark II and the YI M1 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.

Concerning the storage of imaging data, both the G7X Mark II and the M1 write their files to SDXC cards. The G7X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M1 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 PowerShot G7 X Mark II and YI M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M1 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The G7X Mark II does not feature such an accessory-socket.

The M1 is a recent model that features in the current product line-up of YI. In contrast, the G7X Mark II has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G7X Mark II was succeeded by the Canon G7 X Mark III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and YI websites.

Review summary

So what conclusions can be drawn? Is the Canon G7 X Mark II better than the YI M1 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Canon PowerShot G7 X Mark II:

  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens built-in, whereas the M1 requires a separate lens.
  • More compact: Is smaller (106x61mm vs 114x64mm) and thus needs less room in the bag.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • 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.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More heavily discounted: Has been on the market for longer (launched in February 2016).

ilogo

Arguments in favor of the YI M1:

  • 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 video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (450 versus 265) out of a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Was introduced somewhat (7 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the M1 comes out slightly ahead of the G7X Mark II (11 : 10 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 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.

G7X Mark II 10:11 M1

How about other alternatives? Do the specifications of the Canon G7 X Mark II and the YI M1 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 G7X Mark II and the M1 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.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, please note that some of the review sites have changed their methodology and reporting over time.
