Canon 6D Mark II versus Canon 1D Mark III

The Canon EOS 6D Mark II and the Canon EOS-1D Mark III are two digital cameras that were officially introduced, respectively, in June 2017 and February 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (6D Mark II) and an APS-H (1D Mark III) sensor. The 6D Mark II has a resolution of 26 megapixel, whereas the 1D Mark III provides 10.1 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 6D Mark II vs Canon 1D Mark III

An illustration of the physical size and weight of the Canon 6D Mark II and the Canon 1D Mark III 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 you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 6D Mark II – represents 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 Mark III is considerably larger (53 percent) than the Canon 6D Mark II. Moreover, the 1D Mark III is substantially heavier (51 percent) than the 6D 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. A larger imaging sensor (as in the 6D Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (1D Mark III). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 6D Mark II gets 1200 shots out of its LP-E6N battery, while the 1D Mark III can take 2200 images on a single charge of its LP-E4 power pack. As can be seen in the images above, the 1D Mark III has a battery grip build in. This facilitates image-taking in portrait orientation and contributes to its long-lasting power supply. In order to provide similar functionality for the 6D Mark II, Canon provides the BG-E21 vertical grip as an optional accessory (see here on eBay).

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The camera’s price is obviously a critical decision-making factor. 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 6D Mark II was launched at a markedly lower price (by 56 percent) than the 1D 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.

 

Sensor comparison: Canon 6D Mark II vs Canon 1D Mark III

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 6D Mark II features a full frame sensor and the Canon 1D Mark III an APS-H sensor. The sensor area in the 1D Mark III is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 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 6D Mark II uses a more advanced image processing engine (DIGIC 7) than the 1D Mark III (DIGIC III), with benefits for noise reduction, color accuracy, and processing speed.

Canon 6D Mark II and Canon 1D Mark III sensor measures

With 26MP, the 6D Mark II offers a higher resolution than the 1D Mark III (10.1MP), but the 6D Mark II has smaller individual pixels (pixel pitch of 5.76μm versus 7.21μm for the 1D Mark III). However, the 6D Mark II is a somewhat more recent model (by 10 years and 4 months) than the 1D Mark III, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

6D Mark II versus 1D Mark III MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the 6D Mark II provides substantially higher image quality than the 1D Mark III, with an overall score that is 14 points higher. This advantage is based on 1.7 bits higher color depth, 0.2 EV in additional dynamic range, and 1.4 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 are not only capable of taking still images, but can also record movies. The 6D Mark II indeed provides movie recording capabilities, while the 1D Mark III does not. The highest resolution format that the 6D Mark II can use is 1080/60p.

 

Feature comparison: Canon 6D Mark II vs Canon 1D Mark III

Apart from body and sensor, cameras can and do differ across a range of features. The 6D Mark II and the 1D 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 table below summarizes some of the other core capabilities of the Canon 6D Mark II and Canon 1D Mark III in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 6D Mark II has a touchscreen, while the 1D Mark III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point or for making menu selections.

The 6D Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the 1D Mark III has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1D Mark III was succeeded by the Canon 1D Mark IV.

Review summary: Canon 6D Mark II vs Canon 1D Mark III

So what conclusions can be drawn? Is the Canon 6D Mark II better than the Canon 1D Mark III or vice versa? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS 6D Mark II:

  • More detail: Offers more megapixels (26 vs 10.1MP) with a 60% higher linear resolution.
  • Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.7 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.4 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC III).
  • Broader imaging potential: Can record not only still images but also 1080/60p movies.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More compact: Is smaller (144x111mm vs 156x156.6mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 390g or 34 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
  • More modern: Reflects 10 years and 4 months of technical progress since the 1D Mark III launch.


Reasons to prefer the Canon EOS-1D Mark III:

  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 6.5 flaps/sec) to capture the decisive moment.
  • More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
  • Longer lasting: Gets more shots (2200 versus 1200) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in February 2007).

If the number of relative strengths (bullet points above) is taken as a guide, the 6D Mark II is the clear winner of the match-up (13 : 5 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.

6D Mark II 13:05 1D Mark III

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 6D Mark II or the 1D Mark III handle or 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. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
