Canon 100D vs 1Ds Mark III
The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS-1Ds Mark III are two digital cameras that were revealed to the public, respectively, in March 2013 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (100D) and a full frame (1Ds Mark III) sensor. The 100D has a resolution of 17.9 megapixels, whereas the 1Ds Mark III provides 21 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 100D and the Canon EOS-1Ds Mark III? 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 side-by-side display below illustrates the physical size and weight of the Canon 100D and the Canon 1Ds Mark III. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The 100D 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 1Ds Mark III is considerably larger (125 percent) than the Canon 100D. Moreover, the 1Ds Mark III is substantially heavier (240 percent) than the 100D. It is noteworthy in this context that the 1Ds Mark III is splash and dust-proof, while the 100D 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. A larger imaging sensor (as in the 1Ds Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (100D). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 100D gets 380 shots out of its LP-E12 battery, while the 1Ds Mark III can take 1800 images on a single charge of its LP-E4 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. In order to provide similar functionality for the 100D, there are third party battery grips available as optional accessories (see here on eBay).

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 100D was launched at a markedly lower price (by 93 percent) than the 1Ds Mark III, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 100D features an APS-C sensor and the Canon 1Ds Mark III a full frame sensor. The sensor area in the 1Ds Mark III is 160 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. 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 100D (17.9MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 4.31μm for the 100D) due to its larger sensor. However, the 100D is a much more recent model (by 5 years and 7 months) than the 1Ds Mark III, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
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 100D 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 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 100D 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-1Ds Mark III are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-3200.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under consideration, the 1Ds Mark III offers substantially better image quality than the 100D (overall score 17 points higher). The advantage is based on 2.2 bits higher color depth, 0.7 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The 100D indeed provides movie recording capabilities, while the 1Ds Mark III does not. The highest resolution format that the 100D can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 100D and the 1Ds Mark III are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the 1Ds Mark III offers a wider field of view (100%) than the one in the 100D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 1Ds Mark III has a higher magnification (0.76x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 100D and Canon 1Ds Mark III 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 1Ds Mark III 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.
The 100D writes its imaging data to SDXC cards, while the 1Ds Mark III uses Compact Flash or SDHC cards. The 1Ds Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the 100D only has one slot. The 100D 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 100D and Canon EOS-1Ds Mark III 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 100D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 100D and the 1Ds Mark III have been discontinued, but can regularly be found used on eBay. The 1Ds Mark III was replaced by the Canon 1DX, 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.
So what is the bottom line? Which of the two cameras – the Canon 100D or the Canon 1Ds Mark III – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 100D:
- Broader imaging potential: Can record not only still images but also 1080/30p movies.

If the count of individual advantages (bullet points above) is taken as a guide, the 1Ds Mark III is the clear winner of the contest (15 : 10 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 100D and the Canon 1Ds Mark III place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 100D or the 1Ds Mark III. 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 (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 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 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.
