Canon 70D versus Canon 80D

The Canon EOS 70D and the Canon EOS 80D are two enthusiast cameras that were revealed to the public, respectively, in July 2013 and February 2016. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 70D has a resolution of 20 megapixel, whereas the 80D provides 24 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 70D vs Canon 80D

The side-by-side display below illustrates the physical size and weight of the Canon 70D and the Canon 80D. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button 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 70D – 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 70D and the Canon 80Dare of equal size. However, the 80D is slightly lighter (3 percent) than the 70D. 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 70D gets 920 shots out of its LP-E6 battery, while the 80D can take 960 images on a single charge of its LP-E6N power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The two cameras under review were launched at the same price and fall into the same 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 70D vs Canon 80D

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 70D and Canon 80D sensor measures

While the two cameras under review share the same sensor size, the 80D offers a higher resolution of 24 megapixel, compared with 20 MP of the 70D. This megapixel advantage translates into a 10 percent gain in linear resolution. On the other hand, these sensor specs imply that the 80D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.75μm versus 4.11μm for the 70D). However, it should be noted that the 80D is much more recent (by 2 years and 7 months) than the 70D, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

70D versus 80D MP

For most cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the 80D offers substantially better image quality than the 70D (overall score 11 points higher). The advantage is based on 1.1 bits higher color depth, 1.6 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 80D provides a faster frame rate than the 70D. It can shoot movie footage at 1080/60p, while the 70D is limited to 1080/30p.

 

Feature comparison: Canon 70D vs Canon 80D

Apart from body and sensor, cameras can and do differ across a variety of features. The 70D and the 80D 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 70D, the Canon 80D, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The 80D is a current model that online retailers, such as amazon, will have in stock. In contrast, the 70D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 70D was succeeded by the Canon 80D.

Review summary: Canon 70D vs Canon 80D

So what conclusions can be drawn? Is there a clear favorite between the Canon 70D and the Canon 80D? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 70D:

  • More heavily discounted: Has been available for much longer (launched in July 2013).


Reasons to prefer the Canon EOS 80D:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More modern: Reflects 2 years and 7 months of technical progress since the 70D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 80D is the clear winner of the contest (6 : 1 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 70D or the 80D. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. 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 are only valid when refering to cameras in the same category and of the same age. 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, please note that some of the review sites have changed their methodology and reporting over time.
