Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M and the Canon EOS 10D? 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

The side-by-side display below illustrates the physical size and weight of the Canon M and the Canon 10D. 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.

The Canon M can be obtained in two different colors (black, white), while the 10D is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 10D is considerably larger (123 percent) than the Canon M. Moreover, the 10D is substantially heavier (185 percent) than the Canon M. In this context, it is worth noting that neither the Canon M nor the 10D 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.

Concerning battery life, the Canon M gets 230 shots out of its Canon LP-E12 battery, while the 10D can take 500 images on a single charge of its Canon BP-511 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 Canon M was launched at a markedly lower price (by 70 percent) than the 10D, which puts it into a different market segment. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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, but their sensors differ slightly in size. The sensor area in the 10D is 3 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the Canon M uses a more advanced image processing engine (DIGIC V) than the 10D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a slightly smaller sensor, the Canon M offers a higher resolution of 17.9 megapixels, compared with 6.3 MP of the Canon 10D. 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 4.31μm versus 7.38μm for the 10D). However, it should be noted that the Canon M is much more recent (by 9 years and 4 months) than the 10D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon M implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon M for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon 10D are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.

The Canon M has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS M has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS 10D are ISO 100 to ISO 3200 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under review, the Canon M has a notably higher overall DXO score than the 10D (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1 bits higher color depth, 0.3 EV in additional dynamic range, and 0.5 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 cannot only take still pictures, but also record videos. The Canon M indeed provides movie recording capabilities, while the 10D does not. The highest resolution format that the Canon M can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 10D 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 following table reports on some other key feature differences and similarities of the Canon M, the Canon 10D, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Canon M has a touchscreen, while the 10D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon M writes its imaging data to SDXC cards, while the 10D uses Compact Flash cards.

Connectivity comparison

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. The table below provides an overview of the connectivity of the Canon EOS M and Canon EOS 10D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 10D (unlike the Canon M) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the Canon M and the 10D have been discontinued, but can regularly be found used on ebay. The 10D was replaced by the Canon 20D, while the Canon M was followed by the Canon EOS M3. Further information on the features and operation of the Canon M and 10D can be found, respectively, in the Canon M Manual (free pdf) or the online Canon 10D Manual.

Review summary

So how do things add up? Is the Canon M better than the Canon 10D or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS M:

• More detail: Offers more megapixels (17.9 vs 6.3MP) with a 69% higher linear resolution.
• Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (DIGIC V vs DIGIC).
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 118k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (4.3 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (109x66mm vs 150x107mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 552g or 65 percent) and hence easier to carry around.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
• More modern: Reflects 9 years and 4 months of technical progress since the 10D launch.

Arguments in favor of the Canon EOS 10D:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Longer lasting: Gets more shots (500 versus 230) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been around for much longer (launched in February 2003).

If the number of relative strengths (bullet points above) is taken as a guide, the Canon M is the clear winner of the match-up (16 : 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Canon M and the Canon 10D place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

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 Canon M or the 10D perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
