Body comparison: Canon 70D vs 6D Mark II

An illustration of the physical size and weight of the Canon 70D and the Canon 6D Mark II 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 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 – the 70D – 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 Mark II is notably larger (11 percent) than the Canon 70D. Moreover, the 6D Mark II is slightly heavier (1 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. A larger imaging sensor (as in the 6D Mark II) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (70D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 70D gets 920 shots out of its LP-E6 battery, while the 6D Mark II can take 1200 images on a single charge of its LP-E6N power pack.

Any camera decision will obviously take relative prices into account. 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 70D was launched at a markedly lower price (by 40 percent) than the 6D 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.

 

Sensor comparison: Canon 70D vs 6D Mark II

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 70D features an APS-C sensor and the Canon 6D Mark II a full frame sensor. The sensor area in the 6D Mark II is 155 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.

Technology-wise, the 6D Mark II uses a more advanced image processing engine (DIGIC 7) than the 70D (DIGIC 5+), with benefits for noise reduction, color accuracy, and processing speed.

Canon 70D and Canon 6D Mark II sensor measures

With 26MP, the 6D Mark II offers a higher resolution than the 70D (20MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 4.11μm for the 70D) due to its larger sensor. Moreover, the 6D Mark II is a much more recent model (by 3 years and 11 months) than the 70D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The Canon EOS 70D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS 6D Mark II are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400..

70D versus 6D Mark II MP

For many 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 6D Mark II offers substantially better image quality than the 70D (overall score 17 points higher). The advantage is based on 1.9 bits higher color depth, 0.3 EV in additional dynamic range, and 1.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 6D Mark II 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 6D Mark II

Beyond body and sensor, cameras can and do differ across a range of features. The 70D and the 6D Mark II 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 70D and Canon 6D Mark II in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 70D has one, while the 6D Mark II does not. While the built-in flash of the 70D is not very powerful, it can at times be useful as a fill-in light.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

Concerning the storage of imaging data, both the 70D and the 6D Mark II write their files to SDXC cards.

Connectivity comparison: Canon 70D vs 6D Mark II

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 70D and Canon EOS 6D Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The 6D Mark II is a recent model that features in the current product line-up of Canon. 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 6D Mark II

So what is the bottom line? Which of the two cameras – the Canon 70D or the Canon 6D Mark II – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS 70D:

  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • 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 July 2013).


Advantages of the Canon EOS 6D Mark II:

  • More detail: Has more megapixels (26 vs 20MP), which boosts linear resolution by 14%.
  • Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
  • Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 5+).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Longer lasting: Gets more shots (1200 versus 920) out of a single battery charge.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 3 years and 11 months of technical progress since the 70D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 6D Mark II is the clear winner of the contest (10 : 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.

70D 04:10 6D Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 70D or the 6D Mark II handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews: Canon 70D vs 6D Mark II

This is why expert reviews are important.

The review scores listed above should be treated with care, though. The ratings are only valid when referring 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 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.
