Canon 100D vs 6D

The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS 6D are two digital cameras that were revealed to the public, respectively, in March 2013 and September 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (100D) and a full frame (6D) sensor. The 100D has a resolution of 17.9 megapixels, whereas the 6D provides 20 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 100D vs 6D

The side-by-side display below illustrates the physical size and weight of the Canon 100D and the Canon 6D. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

Compare 100D or 6D rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 6D is considerably larger (51 percent) than the Canon 100D. Moreover, the 6D is substantially heavier (89 percent) than the 100D. It is noteworthy in this context that the 6D is splash and dust-proof, while the 100D does not feature any corresponding weather-sealing.

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 (100D). You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 100D gets 380 shots out of its LP-E12 battery, while the 6D can take 1090 images on a single charge of its LP-E6 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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 100D was launched at a markedly lower price (by 74 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: Canon 100D vs 6D

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 100D features an APS-C sensor and the Canon 6D a full frame sensor. The sensor area in the 6D is 160 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 uses a more advanced image processing engine (DIGIC 5+) than the 100D (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.

Canon 100D and Canon 6D sensor measures

With 20MP, the 6D offers a higher resolution than the 100D (17.9MP), but the 6D nevertheless has larger individual pixels (pixel pitch of 6.57μm versus 4.31μm for the 100D) due to its larger sensor. However, the 100D is a somewhat more recent model (by 6 months) than the 6D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon EOS 100D 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 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400..

100D versus 6D MP

For many 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 consideration, the 6D offers substantially better image quality than the 100D (overall score 19 points higher). The advantage is based on 2 bits higher color depth, 0.8 EV in additional dynamic range, and 1.5 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 have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).

 

Feature comparison: Canon 100D vs 6D

Apart from body and sensor, cameras can and do differ across a variety of features. The 100D and the 6D 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 adjacent table lists some of the other core features of the Canon 100D and Canon 6D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 100D has one, while the 6D does not. While the built-in flash of the 100D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 100D and the 6D write their files to SDXC cards.

 

Connectivity comparison: Canon 100D vs 6D

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.

It is notable that the 6D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 100D does not offer wifi capability.

Both the 100D and the 6D have been discontinued, but can regularly be found used on eBay. The 6D was replaced by the Canon 6D Mark II, while the 100D was followed by the Canon 200D.


Review summary: Canon 100D vs 6D

So what is the bottom line? Which of the two cameras – the Canon 100D or the Canon 6D – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 100D:

  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More compact: Is smaller (117x91mm vs 145x111mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 363g or 47 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (74 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 6 months after the 6D).


Advantages of the Canon EOS 6D:

  • More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
  • Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.5 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC 5).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (1090 versus 380) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More heavily discounted: Has been on the market for longer (launched in September 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the 6D is the clear winner of the contest (11 : 7 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.

100D 07:11 6D

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 100D or the 6D handle or perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
