Canon 6D Mark II versus Canon 5D Mark III
The Canon EOS 6D Mark II and the Canon EOS 5D Mark III are two enthusiast cameras that were announced, respectively, in June 2017 and March 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The 6D Mark II has a resolution of 26 megapixel, whereas the 5D Mark III provides 22.1 MP.
An illustration of the physical size and weight of the Canon 6D Mark II and the Canon 5D Mark III is provided in the side-by-side display below. 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 5D Mark III is notably larger (10 percent) than the Canon 6D Mark II. Moreover, the 5D Mark III is markedly heavier (24 percent) than the 6D Mark II. Cameras intended for semi-professional or professional use tend to be a bit bulkier in order to give them the necessary ruggedness. 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 6D Mark II was launched at a markedly lower price (by 43 percent) than the 5D 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a slightly smaller sensor, the Canon 6D Mark II offers a higher resolution of 26 megapixel, compared with 22.1 MP of the Canon 5D Mark III. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.75μm versus 6.25μm for the 5D Mark III). However, it should be noted that the 6D Mark II is much more recent (by 5 years and 3 months) than the 5D Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
For most 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 has a notably higher overall DXO score than the 6D Mark II (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.2 EV in additional dynamic range, and 0.3 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 6D Mark II provides a higher frame rate than the 5D Mark III. It can shoot video footage at 1080/60p, while the 5D Mark III is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The 6D Mark II and the 5D 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 5D Mark III in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The 6D Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the 5D Mark III has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 5D Mark III was succeeded by the Canon 5D Mark IV.
So what conclusions can be drawn? Which of the two cameras – the Canon 6D Mark II or the Canon 5D Mark III – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS 6D Mark II:
- More detail: Offers more megapixels (26 vs 22.1MP) with a 8% higher linear resolution.
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
- More flexible LCD: Has a 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.
- Less heavy: Is lighter (by 185g or 19 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (1200 versus 950) on a single battery charge.
- More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
- More modern: Reflects 5 years and 3 months of technical progress since the 5D Mark III launch.
Arguments in favor of the Canon EOS 5D Mark III:
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- More heavily discounted: Has been around for much longer (launched in March 2012).
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 (9 : 3 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the 6D Mark II and the 5D Mark III 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. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering 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 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.
