Body comparison

The physical size and weight of the Canon 1D Mark II and the Canon R3 are illustrated 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 width, height and depth dimensions are rounded to the nearest millimeter.

Size Canon 1D Mark II vs Canon R3
Compare 1D Mark II versus R3 top
Comparison 1D Mark II or R3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon R3 is notably smaller (13 percent) than the Canon 1D Mark II. Moreover, the R3 is markedly lighter (34 percent) than the 1D Mark II. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 1D Mark II gets 1200 shots out of its Canon NP-E3 battery, while the R3 can take 760 images on a single charge of its Canon LP-E19 power pack. As can be seen in the images above, both cameras have a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the R3 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 1D Mark II was launched at a somewhat lower price (by 25 percent) than the R3, which makes it more attractive for photographers on a tight budget. 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.

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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D Mark II features an APS-H sensor and the Canon R3 a full frame sensor. The sensor area in the R3 is 58 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the R3 uses a more advanced image processing engine (DIGIC X) than the 1D Mark II (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

Canon 1D Mark II and Canon R3 sensor measures

With 24MP, the R3 offers a higher resolution than the 1D Mark II (8.2MP), but the R3 has smaller individual pixels (pixel pitch of 6.00μm versus 8.17μm for the 1D Mark II). Yet, the R3 is a much more recent model (by 17 years and 7 months) than the 1D Mark II, 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 R3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the R3 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 1D Mark II are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.

The R3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1D 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 R3 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

In terms of underlying technology, the 1D Mark II is build around a CMOS sensor, while the R3 uses a Stacked BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

1D Mark II versus R3 MP

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"). Of the two cameras under consideration, the R3 offers substantially better image quality than the 1D Mark II (overall score 30 points higher). The advantage is based on 2.7 bits higher color depth, 3.6 EV in additional dynamic range, and 2 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the R3 has an electronic viewfinder (5760k dots), while the 1D 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 R3 has a higher magnification than the one of the 1D Mark II (0.76x vs 0.55x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1D Mark II and Canon R3 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The R3 has a touchscreen, while the 1D Mark II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The R3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 1D Mark II does not have a selfie-screen.

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 R3 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 R3 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 1D Mark II writes its imaging data to Compact Flash or SD cards, while the R3 uses CFexpress (type B) or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The R3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the 1D Mark II cannot take advantage of Ultra High Speed SD cards.

It is notable that the R3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1D Mark II does not provide wifi capability.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

The R3 is a recent model that features in the current product line-up of Canon. In contrast, the 1D Mark II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 1D Mark II was succeeded by the Canon 1D Mark II N. Further information on the features and operation of the 1D Mark II and R3 can be found, respectively, in the Canon 1D Mark II Manual (free pdf) or the online Canon R3 Manual.

  • More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in January 2004).


Advantages of the Canon EOS R3:

  • More detail: Has more megapixels (24 vs 8.2MP), which boosts linear resolution by 71%.
  • Better image quality: Scores substantially higher (30 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.7 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.6 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC X vs DIGIC II).
  • Broader imaging potential: Can capture not only stills but also 6K/60p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.55x).
  • Larger screen: Has a bigger rear LCD (3.2" vs 2.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (4150k vs 230k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (12 vs 8.3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (150x143mm vs 156x158mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 520g or 34 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.2 vs 1.1).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-II standard.
  • More modern: Reflects 17 years and 7 months of technical progress since the 1D Mark II launch.

If the count of individual advantages (bullet points above) is taken as a guide, the R3 is the clear winner of the contest (28 : 4 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. 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.

1D Mark II 04:28 R3

How about other alternatives? Do the specifications of the Canon 1D Mark II and the Canon R3 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 1D Mark II or the R3 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 following table reports the overall ratings of the cameras as published by some of the major 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
