Canon M100 versus Canon M3

The Canon EOS M100 and the Canon EOS M3 are two digital cameras that were officially introduced, respectively, in August 2017 and February 2015. Both the M100 and the M3 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixel. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon M100 vs Canon M3

The physical size and weight of the Canon M100 and the Canon M3 are illustrated 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 measures are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the M100 – 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 M3 is somewhat larger (4 percent) than the Canon M100. Moreover, the M3 is markedly heavier (21 percent) than the M100. In this context, it is worth noting that neither the M100 nor the M3 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the M100 gets 295 shots out of its LP-E12 battery, while the M3 can take 250 images on a single charge of its LP-E17 power pack.

Any camera purchase will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The M100 was launched at a markedly lower price (by 27 percent) than the M3, which puts it into a different market segment. 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 M100 vs Canon M3

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

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the M100 uses a more advanced image processing engine (DIGIC 7) than the M3 (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.

Canon M100 and Canon M3 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixel. This similarity in sensor specs implies that both the M100 and the M3 have the same pixel density, as well as the same pixel size. It should, however, be noted that the M100 is much more recent (by 2 years and 6 months) than the M3, and its sensor will have benefitted from technological advances during this time.

M100 versus M3 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the M100 has a notably higher overall DXO score than the M3 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 1.1 EV in additional dynamic range, and 0.1 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the M100 provides a higher frame rate than the M3. It can shoot video footage at 1080/60p, while the M3 is limited to 1080/30p.

 

Feature comparison: Canon M100 vs Canon M3

Beyond body and sensor, cameras can and do differ across a range of features. The M100 and the M3 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 M3 can be equipped with an optional viewfinder – the EVF-DC1. The table below summarizes some of the other core capabilities of the Canon M100 and Canon M3 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

The M100 is a current model that online retailers, such as amazon, will have in stock. In contrast, the M3 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the M3 was succeeded by the Canon M6.

Review summary: Canon M100 vs Canon M3

So what is the bottom line? Which of the two cameras – the Canon M100 or the Canon M3 – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS M100:

  • Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.1 EV of extra DR).
  • Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 6).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Faster burst: Shoots at higher frequency (6.1 vs 4.2 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 64g or 17 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (295 versus 250) on a single battery charge.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
  • More modern: Reflects 2 years and 6 months of technical progress since the M3 launch.


Advantages of the Canon EOS M3:

  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been around for much longer (launched in February 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the M100 is the clear winner of the match-up (10 : 3 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.

M100 10:03 M3

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the M100 or the M3 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. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
