Body comparison: Canon M100 vs 1D
An illustration of the physical size and weight of the Canon M100 and the Canon 1D is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions 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 the basis or 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 1D is considerably larger (241 percent) than the Canon M100. Moreover, the 1D is substantially heavier (425 percent) than the M100. It is noteworthy in this context that the 1D is splash and dust-proof, while the M100 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 M100 gets 295 shots out of its LP-E12 battery, while the 1D can take 500 images on a single charge of its NP-E3 power pack. As can be seen in the images above, the 1D has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The M100 was launched at a markedly lower price (by 92 percent) than the 1D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Canon M100 vs 1D
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.
Of the two cameras under consideration, the Canon M100 features an APS-C sensor and the Canon 1D an APS-H sensor. The sensor area in the 1D is 65 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.3. 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 1D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the Canon M100 offers a higher resolution of 24 megapixels, compared with 4.1 MP of the Canon 1D. 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 3.72μm versus 11.56μm for the 1D). However, it should be noted that the M100 is much more recent (by 15 years and 11 months) than the 1D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The M100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Canon EOS M100 has a native sensitivity range from ISO 100 to ISO 25600 The corresponding ISO settings for the Canon EOS-1D are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 100-3200..
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 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 also of capturing video footage. The M100 indeed provides movie recording capabilities, while the 1D does not. The highest resolution format that the M100 can use is 1080/60p.
Feature comparison: Canon M100 vs 1D
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 1D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M100 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon M100 and Canon 1D 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 M100 has one, while the 1D does not. While the built-in flash of the M100 is not very powerful, it can at times be useful as a fill-in light.The M100 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the 1D does not have a selfie-screen.
The M100 writes its imaging data to SDXC cards, while the 1D uses Compact Flash cards. The 1D features dual card slots, which can be very useful in case a memory card fails. In contrast, the M100 only has one slot.
Connectivity comparison: Canon M100 vs 1D
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 M100 and Canon EOS-1D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

If the count of relative strengths (bullet points above) is taken as a measure, the M100 is the clear winner of the match-up (18 : 10 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.
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 handling experience and imaging performance when actually working with the M100 or the 1D. 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
