Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1Ds Mark II and the Canon EOS R100? 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
An illustration of the physical size and weight of the Canon 1Ds Mark II and the Canon R100 is provided 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 width, height and depth measures are rounded to the nearest millimeter.



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon R100 is considerably smaller (60 percent) than the Canon 1Ds Mark II. Moreover, the R100 is substantially lighter (71 percent) than the 1Ds Mark II. It is worth mentioning in this context that the 1Ds Mark II is splash and dust resistant, while the R100 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 II gets 1200 shots out of its Canon NP-E3 battery, while the R100 can take 400 images on a single charge of its Canon LP-E17 power pack. As can be seen in the images above, the 1Ds Mark II 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 R100 was launched at a markedly lower price (by 94 percent) than the 1Ds Mark II, 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
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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 1Ds Mark II features a full frame sensor and the Canon R100 an APS-C sensor. The sensor area in the R100 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.
Technology-wise, the R100 uses a more advanced image processing engine (DIGIC 8) than the 1Ds Mark II (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the R100 offers a higher resolution of 24 megapixels, compared with 16.6 MP of the 1Ds Mark II. 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 7.21μm for the 1Ds Mark II). However, it should be noted that the R100 is much more recent (by 18 years and 8 months) than the 1Ds Mark II, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the R100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon R100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon 1Ds Mark II are 25 x 16.6 inches or 63.4 x 42.3 cm for good quality, 20 x 13.3 inches or 50.7 x 33.8 cm for very good quality, and 16.6 x 11.1 inches or 42.3 x 28.2 cm for excellent quality prints.
The R100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS-1Ds Mark II 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 R100 are ISO 100 to ISO 25600 (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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The R100 indeed provides for movie recording, while the 1Ds Mark II does not. The highest resolution format that the R100 can use is 4k/24p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the R100 has an electronic viewfinder (2360k dots), while the 1Ds Mark II has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the 1Ds Mark II has a higher magnification than the one of the R100 (0.70x vs 0.58x), 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 1Ds Mark II and Canon R100 in connection with corresponding information for a sample of similar cameras.

| Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. | |||||||||||
One feature that is present on the 1Ds Mark II, but is missing on the R100 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 reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the R100 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Canon R100 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The 1Ds Mark II writes its imaging data to Compact Flash or SDHC cards, while the R100 uses SDXC cards. The 1Ds Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the R100 only has one slot. The R100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 1Ds Mark II cannot take advantage of Ultra High Speed SD 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.

It is notable that the R100 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1Ds Mark II does not provide wifi capability.
Studio photographers will appreciate that the Canon 1Ds Mark II (unlike the R100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The R100 is a recent model that features in the current product line-up of Canon. In contrast, the 1Ds Mark II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 1Ds Mark II was succeeded by the Canon 1Ds Mark III. Further information on the features and operation of the 1Ds Mark II and R100 can be found, respectively, in the Canon 1Ds Mark II Manual (free pdf) or the online Canon R100 Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Canon 1Ds Mark II or the Canon R100 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the R100 is the clear winner of the contest (20 : 11 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 II and the Canon R100 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 II or the R100. 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.
Expert reviews
This is where reviews by experts come in. 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 are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
