Body comparison: Canon G5 X vs M100

The physical size and weight of the Canon G5 X and the Canon M100 are illustrated 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 size 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 G5X – represents 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 M100 is notably smaller (15 percent) than the Canon G5 X. In this context, it is worth noting that neither the G5X nor the M100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G5X has a lens built in, whereas the M100 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 G5X gets 210 shots out of its NB-13L battery, while the M100 can take 295 images on a single charge of its LP-E12 power pack.

The price is, of course, an important factor in any camera decision. 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. 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: Canon G5 X vs M100

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G5 X features an one-inch sensor and the Canon M100 an APS-C sensor. The sensor area in the M100 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.

Technology-wise, the M100 uses a more advanced image processing engine (DIGIC 7) than the G5X (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.

Canon G5 X and Canon M100 sensor measures

With 24MP, the M100 offers a higher resolution than the G5X (20MP), but the M100 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G5X) due to its larger sensor. Moreover, the M100 is a somewhat more recent model (by 1 year and 10 months) than the G5X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The M100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon PowerShot G5 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 M100 are ISO 100 to ISO 25600 (no boost).

G5X versus M100 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

It is notable that the G5X has a hotshoe, while the M100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the G5X and the M100 are recent models that feature in their makers' current product line-up. The M100 replaced the earlier Canon M10, while the G5X does not have a direct predecessor.


Review summary: Canon G5 X vs M100

So what conclusions can be drawn? Is there a clear favorite between the Canon G5 X and the Canon M100? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon PowerShot G5 X:

  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Ready to shoot: Has a lens built-in, whereas the M100 requires a separate lens.
  • 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 October 2015).


Advantages of the Canon EOS M100:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Richer colors: Larger sensor generates images with better, more accurate colors.
  • More dynamic range: Capable of capturing a wider spectrum of light and dark details.
  • Better low-light sensitivity: Can be used in poorly lit environments and still produce good images.
  • Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 6).
  • 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 112x76mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (295 versus 210) out of a single battery charge.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Was introduced somewhat (1 year and 10 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the M100 is the clear winner of the contest (13 : 6 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.

G5X 06:13 M100

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G5X and the M100 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
