Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 6D and the Canon EOS 5D Mark IV? 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

The side-by-side display below illustrates the physical size and weight of the Canon 6D and the Canon 5D Mark IV. 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 5D Mark IV is notably larger (9 percent) than the Canon 6D. Moreover, the 5D Mark IV is markedly heavier (16 percent) than the 6D. 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 compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 6D gets 1090 shots out of its Canon LP-E6 battery, while the 5D Mark IV can take 900 images on a single charge of its Canon LP-E6N power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. 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 6D was launched at a markedly lower price (by 40 percent) than the 5D Mark IV, 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 imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 5D Mark IV uses a more advanced image processing engine (DIGIC 6+) than the 6D (DIGIC 5+), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the 5D Mark IV offers a higher resolution of 30.1 megapixels, compared with 20 MP of the 6D. This megapixels advantage translates into a 23 percent gain in linear resolution. On the other hand, these sensor specs imply that the 5D Mark IV has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.36μm versus 6.57μm for the 6D). However, it should be noted that the 5D Mark IV is much more recent (by 3 years and 11 months) than the 6D, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Canon 5D Mark IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark IV for good quality output (200 dots per inch) amounts to 33.6 x 22.4 inches or 85.3 x 56.9 cm, for very good quality (250 dpi) 26.9 x 17.9 inches or 68.3 x 45.5 cm, and for excellent quality (300 dpi) 22.4 x 14.9 inches or 56.9 x 37.9 cm. The corresponding values for the Canon 6D are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The 5D Mark IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 6D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon EOS 5D Mark IV are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 5D Mark IV has a markedly higher DXO score than the 6D (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 1.5 EV in additional dynamic range, and 0.4 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 5D Mark IV provides a better video resolution than the 6D. It can shoot movie footage at 4K/30p, while the 6D is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 6D and the 5D Mark IV 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 viewfinders of both cameras offer the same magnification (0.71x), but the one in the 5D Mark IV has a wider field of view (100%) than the finder in the 6D (97%), so that a larger proportion of the captured image is visible. The table below summarizes some of the other core capabilities of the Canon 6D and Canon 5D Mark IV in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 5D Mark IV has a touchscreen, while the 6D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon 5D Mark IV 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 6D writes its imaging data to SDXC cards, while the 5D Mark IV uses Compact Flash or SDXC cards. The 5D Mark IV features dual card slots, which can be very useful in case a memory card fails. In contrast, the 6D only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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. The table below provides an overview of the connectivity of the Canon EOS 6D and Canon EOS 5D Mark IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5D Mark IV has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The 6D lacks such a headphone port.

Studio photographers will appreciate that the Canon 5D Mark IV (unlike the 6D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that both cameras feature internal geolocalization sensors and can record GPS coordinates in their EXIF data.

The 5D Mark IV is a recent model that features in the current product line-up of Canon. In contrast, the 6D has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the 6D was succeeded by the Canon 6D Mark II. Further information on the features and operation of the 6D and 5D Mark IV can be found, respectively, in the Canon 6D Manual (free pdf) or the online Canon 5D Mark IV Manual.

Review summary

So what conclusions can be drawn? Is the Canon 6D better than the Canon 5D Mark IV or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS 6D:

• Less heavy: Is lighter (by 120g or 13 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (1090 versus 900) on a single battery charge.
• More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in September 2012).

Advantages of the Canon EOS 5D Mark IV:

• More detail: Has more megapixels (30.1 vs 20MP), which boosts linear resolution by 23%.
• Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (DIGIC 6+ vs DIGIC 5+).
• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More complete view: Has a viewfinder with a larger field of view (100% vs 97%).
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (7 vs 4.5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Reflects 3 years and 11 months of technical progress since the 6D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 5D Mark IV is the clear winner of the contest (21 : 4 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 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 6D and the Canon 5D Mark IV 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 says little about, for example, the shooting experience and imaging performance of the 6D and the 5D Mark IV in practical situations. 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 expert reviews are important. 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.

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

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
