Body comparison: Canon G3 X vs M10

An illustration of the physical size and weight of the Canon G3 X and the Canon M10 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 you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the G3X – represents the basis or 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M10 is notably smaller (24 percent) than the Canon G3 X. It is worth mentioning in this context that the G3X is splash and dust resistant, while the M10 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G3X has a lens built in, whereas the M10 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 M10 can take 255 images on a single charge of its LP-E12 power pack.

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

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. 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: Canon G3 X vs M10

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

Of the two cameras under consideration, the Canon G3 X features an one-inch sensor and the Canon M10 an APS-C sensor. The sensor area in the M10 is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G3 X and Canon M10 sensor measures

Despite having a smaller sensor, the Canon G3 X offers a higher resolution of 20 megapixels, compared with 17.9 MP of the Canon M10. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.31μm for the M10). Moreover, it should be noted that the M10 is a somewhat more recent model (by 3 months) than the G3X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The M10 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

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 M10 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600..

G3X versus M10 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 have a sensor with sufficiently fast read-out times for moving pictures, but the G3X provides a higher frame rate than the M10. It can shoot video footage at 1080/60p, while the M10 is limited to 1080/30p.

 

Feature comparison: Canon G3 X vs M10

Beyond body and sensor, cameras can and do differ across a range of features. The G3X and the M10 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. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The adjacent table lists some of the other core features of the Canon G3 X and Canon M10 along with similar information for a selection of comparators.

It is notable that the G3X has a hotshoe, while the M10 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The G3X is a recent model that features in the current product line-up of Canon. In contrast, the M10 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the M10 was succeeded by the Canon M100.


Review summary: Canon G3 X vs M10

So how do things add up? Is there a clear favorite between the Canon G3 X and the Canon M10? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Canon PowerShot G3 X:

  • More detail: Offers more megapixels (20 vs 17.9MP) with a 6% higher linear resolution.
  • More dynamic range: Captures a larger spectrum of light and dark details (0.9 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • 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 framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • 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 (1620k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (5.9 vs 4.6 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens built-in, whereas the M10 requires a separate lens.
  • Longer lasting: Can take more shots (300 versus 255) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been on the market for longer (launched in June 2015).


Advantages of the Canon EOS M10:

  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • More compact: Is smaller (108x67mm vs 123x77mm) and will fit more readily into a bag.
  • More modern: Was introduced somewhat (3 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the G3X is the clear winner of the match-up (15 : 6 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.

G3X 15:06 M10

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 G3X or the M10 handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
