Canon 1Ds Mark II versus Canon 6D

The Canon EOS-1Ds Mark II and the Canon EOS 6D are two digital cameras that were revealed to the public, respectively, in September 2004 and September 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The 1Ds Mark II has a resolution of 16.6 megapixel, whereas the 6D provides 20 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 1Ds Mark II vs Canon 6D

The physical size and weight of the Canon 1Ds Mark II and the Canon 6D 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 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 1Ds Mark II – 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 6D is considerably smaller (35 percent) than the Canon 1Ds Mark II. Moreover, the 6D is substantially lighter (37 percent) than the 1Ds 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 1Ds Mark II gets 1200 shots out of its NP-E3 battery, while the 6D can take 1090 images on a single charge of its LP-E6 power pack. As can be seen in the images above, the 1Ds Mark II has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the 6D, Canon provides the BG-E13 vertical grip as an optional accessory (see here on eBay).

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 was launched at a markedly lower price (by 74 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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

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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the 6D uses a more advanced image processing engine (DIGIC 5+) than the 1Ds Mark II (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the 6D offers a higher resolution of 20 megapixel, compared with 16.6 MP of the 1Ds Mark II. This megapixel advantage translates into a 10 percent gain in linear resolution. On the other hand, these sensor specs imply that the 6D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 6.57μm versus 7.21μm for the 1Ds Mark II). However, it should be noted that the 6D is much more recent (by 7 years and 11 months) than the 1Ds Mark II, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the 6D has a markedly higher DXO score than the 1Ds Mark II (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.5 bits higher color depth, 0.8 EV in additional dynamic range, and 0.7 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 indeed provides for movie recording, while the 1Ds Mark II does not. The highest resolution format that the 6D can use is 1080/30p.

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

Beyond body and sensor, cameras can and do differ across a range of features. The 1Ds Mark II and the 6D 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 following table reports on some other key feature differences and similarities of the Canon 1Ds Mark II, the Canon 6D, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The 1Ds Mark II writes its imaging data to Compact Flash cards, while the 6D 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 6D only has one slot.

Both the 1Ds Mark II and the 6D have been discontinued, but can regularly be found used on eBay. The 1Ds Mark II was replaced by the Canon 1Ds Mark III, while the 6D was followed by the Canon 6D Mark II.

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

So what conclusions can be drawn? Which of the two cameras – the Canon 1Ds Mark II or the Canon 6D – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS-1Ds Mark II:

• Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (1200 versus 1090) on a single battery charge.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in September 2004).

Arguments in favor of the Canon EOS 6D:

• More detail: Has more megapixels (20 vs 16.6MP), which boosts linear resolution by 10%.
• Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC II).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Faster burst: Shoots at higher frequency (4.5 vs 4 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (145x111mm vs 156x157.6mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 445g or 37 percent) and is thus easier to take along.
• Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
• More affordable: Was introduced into a lower priced category (74 percent cheaper at launch).
• More modern: Reflects 7 years and 11 months of technical progress since the 1Ds Mark II launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 6D is the clear winner of the contest (14 : 5 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 1Ds Mark II or the 6D. 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. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, 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 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.
