Canon 6D versus Canon 70D

The Canon EOS 6D and the Canon EOS 70D are two digital cameras that were announced, respectively, in September 2012 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (6D) and an APS-C sensor. Both cameras offer a resolution of 20 megapixel.

Body comparison

The physical size and weight of the Canon 6D and the Canon 70D are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size 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 6D – 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 is notably smaller (10 percent) than the Canon 6D. Moreover, the 70D is slightly lighter (2 percent) than the 6D. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with 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. A larger imaging sensor (as in the 6D) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (70D). You can find a comprehensive 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 70D was launched at a markedly lower price (by 43 percent) than the 6D, 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.

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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 6D features a full frame sensor and the Canon 70D an APS-C sensor. The sensor area in the 70D is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

Even though the 6D has a larger sensor, both cameras offer the same resolution of 20 megapixel. This implies that the 6D has a lower pixel density and larger individual pixels (with a pixel pitch of 6.58μm versus 4.11μm for the 70D), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the 70D is a somewhat more recent model (by 9 months) than the 6D, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. 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 review, the 6D provides substantially higher image quality than the 70D, with an overall score that is 14 points higher. This advantage is based on 1.3 bits higher color depth, 0.5 EV in additional dynamic range, and 1.3 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 6D and the 70D 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 and Canon 70D in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the 6D and the 70D have been discontinued, but can regularly be found used on ebay. The 6D was replaced by the Canon 6D Mark II, while the 70D was followed by the Canon 80D.

Summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 6D and the Canon 6D? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS 6D:

  • Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.3 stops ISO advantage).
  • Longer lasting: Can take more shots (1090 versus 920) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in September 2012).

Reasons to prefer the Canon EOS 70D:

  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (7 vs 4.5 flaps/sec) to capture the decisive moment.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (43 percent cheaper at launch).
  • More modern: Was introduced somewhat (9 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the 70D emerges as the winner of the match-up (7 : 5 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.

6D 05:07 70D

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 6D or the 70D 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 hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
