Canon M10 versus Canon 40D

The Canon EOS M10 and the Canon EOS 40D are two digital cameras that were announced, respectively, in October 2015 and August 2007. The M10 is a mirrorless interchangeable lens camera, while the 40D is a DSLR. Both cameras are equipped with an APS-C sensor. The M10 has a resolution of 17.9 megapixel, whereas the 40D provides 10.1 MP. 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 M10 vs Canon 40D

The physical size and weight of the Canon M10 and the Canon 40D 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 dimensions are rounded to the nearest millimeter. You can also toggle the display 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 side – the M10 – represents the basis for the calculations 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 40D is considerably larger (118 percent) than the Canon M10. Moreover, the 40D is substantially heavier (173 percent) than the M10. In this context, it is worth noting that neither the M10 nor the 40D 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 M10 gets 255 shots out of its LP-E12 battery, while the 40D can take 750 images on a single charge of its BP-511A power pack.

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

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M10 was launched at a markedly lower price (by 62 percent) than the 40D, 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 M10 vs Canon 40D

The size of the imaging sensor is a crucial determinant 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. 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 M10 uses a more advanced image processing engine (DIGIC 6) than the 40D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Canon M10 and Canon 40D sensor measures

While the two cameras under review share the same sensor size, the M10 offers a higher resolution of 17.9 megapixel, compared with 10.1 MP of the 40D. This megapixel advantage translates into a 33 percent gain in linear resolution. On the other hand, these sensor specs imply that the M10 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 5.73μm for the 40D). In this context, it should be noted, however, that the M10 is much more recent (by 8 years and 1 month) than the 40D, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

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

M10 versus 40D 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 image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The M10 indeed provides movie recording capabilities, while the 40D does not. The highest resolution format that the M10 can use is 1080/30p.

 

Feature comparison: Canon M10 vs Canon 40D

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 40D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M10 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon M10, the Canon 40D, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Review summary: Canon M10 vs Canon 40D

So what is the bottom line? Is there a clear favorite between the Canon M10 and the Canon 40D? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon EOS M10:

  • More detail: Offers more megapixels (17.9 vs 10.1MP) with a 33% higher linear resolution.
  • Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 3).
  • Broader imaging potential: Can record not only still images but also 1080/30p movies.
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More compact: Is smaller (108x67mm vs 146x108mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 521g or 63 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (62 percent cheaper at launch).
  • More modern: Reflects 8 years and 1 month of technical progress since the 40D launch.


Arguments in favor of the Canon EOS 40D:

  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (6.5 vs 4.6 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (750 versus 255) out of a single battery charge.
  • 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 August 2007).

If the count of individual advantages (bullet points above) is taken as a guide, the M10 is the clear winner of the match-up (14 : 7 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.

M10 14:07 40D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the M10 and the 40D 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. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
