Canon 1Ds Mark III vs Canon M
The Canon EOS-1Ds Mark III and the Canon EOS M are two digital cameras that were officially introduced, respectively, in August 2007 and July 2012. The 1Ds Mark III is a DSLR, while the Canon M is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1Ds Mark III) and an APS-C (Canon M) sensor. The 1Ds Mark III has a resolution of 21 megapixels, whereas the Canon M provides 17.9 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds Mark III 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.
The physical size and weight of the Canon 1Ds Mark III and the Canon M are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The Canon M can be obtained in two different colors (black, white), while the 1Ds Mark III 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 M is considerably smaller (70 percent) than the Canon 1Ds Mark III. Moreover, the Canon M is substantially lighter (78 percent) than the 1Ds Mark III. It is worth mentioning in this context that the 1Ds Mark III is splash and dust resistant, while the Canon M does not feature any corresponding weather-sealing.
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 1Ds Mark III gets 1800 shots out of its LP-E4 battery, while the Canon M can take 230 images on a single charge of its LP-E12 power pack. As can be seen in the images above, the 1Ds Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.
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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon M was launched at a markedly lower price (by 93 percent) than the 1Ds Mark III, 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.
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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 1Ds Mark III features a full frame sensor and the Canon M an APS-C sensor. The sensor area in the Canon M is 62 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 21MP, the 1Ds Mark III offers a higher resolution than the Canon M (17.9MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.31μm for the Canon M) due to its larger sensor. However, the Canon M is a much more recent model (by 4 years and 11 months) than the 1Ds Mark III, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 1Ds Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 1Ds Mark III for good quality output (200 dots per inch) amounts to 28.1 x 18.7 inches or 71.3 x 47.5 cm, for very good quality (250 dpi) 22.5 x 15 inches or 57.1 x 38 cm, and for excellent quality (300 dpi) 18.7 x 12.5 inches or 47.5 x 31.7 cm. The corresponding values for the Canon M are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 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-1Ds Mark III has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Canon EOS M are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 1Ds Mark III provides substantially higher image quality than the Canon M, with an overall score that is 15 points higher. This advantage is based on 1.9 bits higher color depth, 0.8 EV in additional dynamic range, and 1 stops in additional low light sensitivity. 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 Canon M indeed provides for movie recording, while the 1Ds Mark III does not. The highest resolution format that the Canon M can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 1Ds Mark III 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 1Ds Mark III and Canon M in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1Ds Mark III, but is missing on the Canon M is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The 1Ds Mark III writes its imaging data to Compact Flash or SDHC cards, while the Canon M uses SDXC cards. The 1Ds Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the Canon M only has one slot. The Canon M supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1Ds Mark III cannot take advantage of Ultra High Speed SD cards.
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-1Ds Mark III and Canon EOS M and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1Ds Mark III (unlike the Canon M) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 1Ds Mark III and the Canon M have been discontinued, but can regularly be found used on eBay. The 1Ds Mark III was replaced by the Canon 1DX, while the Canon M was followed by the Canon EOS M3. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Is the Canon 1Ds Mark III better than the Canon M or vice versa? A synthesis of the relative strong points of each of the models is listed below.

If the number of relative strengths (bullet points above) is taken as a guide, the 1Ds Mark III is the clear winner of the match-up (15 : 10 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.
How about other alternatives? Do the specifications of the Canon 1Ds Mark III 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1Ds Mark III or the Canon M. 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.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
