Canon 80D versus Canon 5D Mark III

The Canon EOS 80D and the Canon EOS 5D Mark III are two digital cameras that were announced, respectively, in February 2016 and March 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (80D) and a full frame (5D Mark III) sensor. The 80D has a resolution of 24 megapixel, whereas the 5D Mark III provides 22.1 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 80D vs Canon 5D Mark III

An illustration of the physical size and weight of the Canon 80D and the Canon 5D Mark III is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the 80D – represents the basis for the calculations 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 (21 percent) than the Canon 80D. Moreover, the 5D Mark III is markedly heavier (30 percent) than the 80D. 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 5D Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (80D). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 80D gets 960 shots out of its LP-E6N battery, while the 5D Mark III can take 950 images on a single charge of its LP-E6 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 price is, of course, an important factor in any camera decision. 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 80D was launched at a markedly lower price (by 66 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.

 

Sensor comparison: Canon 80D vs Canon 5D Mark III

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 80D features an APS-C sensor and the Canon 5D Mark III a full frame sensor. The sensor area in the 5D Mark III is 156 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the 80D uses a more advanced image processing engine (DIGIC 6) than the 5D Mark III (DIGIC 5+), with benefits for noise reduction, color accuracy, and processing speed.

Canon 80D and Canon 5D Mark III sensor measures

Despite having a smaller sensor, the Canon 80D offers a higher resolution of 24 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 3.75μm versus 6.25μm for the 5D Mark III). However, it should be noted that the 80D is much more recent (by 3 years and 11 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.

80D versus 5D Mark III MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 have a sensor with sufficiently fast read-out times for moving pictures, but the 80D 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.

 

Feature comparison: Canon 80D vs Canon 5D Mark III

Apart from body and sensor, cameras can and do differ across a range of features. The 80D 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 following table reports on some other key feature differences and similarities of the Canon 80D, the Canon 5D Mark III, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 80D has one, while the 5D Mark III does not. While the build-in flash of the 80D is not very powerful, it can at times be useful as a fill-in light.

The 80D writes its imaging data to SDXC cards, while the 5D Mark III uses Compact Flash cards. The 5D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the 80D only has one slot.

The 80D 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.

Review summary: Canon 80D vs Canon 5D Mark III

So what conclusions can be drawn? Which of the two cameras – the Canon 80D or the Canon 5D Mark III – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 80D:

  • More dynamic range: Captures a larger spectrum of light and dark details (1.5 EV of extra DR).
  • Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 5+).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • 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.
  • Faster burst: Shoots at higher frequency (7 vs 6 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (139x105mm vs 152x116mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 220g or 23 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced into a lower priced category (66 percent cheaper at launch).
  • More modern: Reflects 3 years and 11 months of technical progress since the 5D Mark III launch.


Reasons to prefer the Canon EOS 5D Mark III:

  • Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in March 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the 80D is the clear winner of the match-up (13 : 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.

80D 13:04 5D Mark III

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 80D or the 5D 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 expert reviews 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
