Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 100D and the Canon EOS M? 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: Canon 100D vs Canon M

The side-by-side display below illustrates the physical size and weight of the Canon 100D and the Canon M. 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.

Both cameras are available in two different colors (black, white).

Size Canon 100D vs Canon M
Compare 100D versus Canon M top
Comparison 100D or Canon M rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M is considerably smaller (32 percent) than the Canon 100D. Moreover, the Canon M is markedly lighter (27 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the Canon M 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 and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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

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. The 100D was somewhat cheaper (by 8 percent) than the Canon M at launch, but both cameras fall into the same price category. 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 100D vs Canon M

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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.

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.

Canon 100D and Canon M sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 17.9 megapixels. This similarity in sensor specs implies that both the 100D and the Canon M have the same pixel density, as well as the same pixel size. It should, however, be noted that the 100D is a somewhat more recent model (by 7 months) than the Canon M, and its sensor might have benefitted from technological advances during this time.

The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The Canon EOS M offers exactly the same ISO settings.

100D versus Canon M 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).

 

Feature comparison: Canon 100D vs Canon M

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 100D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Canon M relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 100D and Canon M in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 100D has one, while the Canon M does not. While the built-in flash of the 100D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 100D and the Canon M write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison: Canon 100D vs Canon M

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.

Both the 100D and the Canon M have been discontinued, but can regularly be found used on eBay. The Canon M was replaced by the Canon EOS M3, while the 100D was followed by the Canon 200D. 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: Canon 100D vs Canon M

So how do things add up? Is there a clear favorite between the Canon 100D and the Canon M? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon EOS 100D:

  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Faster burst: Shoots at higher frequency (4.9 vs 4.3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (380 versus 230) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More modern: Is somewhat more recent (announced 7 months after the Canon M).


Advantages of the Canon EOS M:

  • More compact: Is smaller (109x66mm vs 117x91mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 109g or 27 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More heavily discounted: Has been on the market for longer (launched in July 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the 100D comes out slightly ahead of the Canon M (5 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

100D 05:04 Canon M

How about other alternatives? Do the specifications of the Canon 100D and the Canon M place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 100D or the Canon M. 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: Canon 100D vs Canon M

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 (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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
