Canon 6D vs M100

The Canon EOS 6D and the Canon EOS M100 are two digital cameras that were officially introduced, respectively, in September 2012 and August 2017. The 6D is a DSLR, while the M100 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (6D) and an APS-C (M100) sensor. The 6D has a resolution of 20 megapixels, whereas the M100 provides 24 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 6D and the Canon EOS M100? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 6D and the Canon M100. 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.

The M100 can be obtained in two different colors (black, white), while the 6D is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M100 is considerably smaller (55 percent) than the Canon 6D. Moreover, the M100 is substantially lighter (61 percent) than the 6D. It is worth mentioning in this context that the 6D is splash and dust resistant, while the M100 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the 6D gets 1090 shots out of its LP-E6 battery, while the M100 can take 295 images on a single charge of its LP-E12 power pack.

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

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 M100 was launched at a markedly lower price (by 76 percent) than the 6D, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend 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 M100 an APS-C sensor. The sensor area in the M100 is 62 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.

Technology-wise, the M100 uses a more advanced image processing engine (DIGIC 7) than the 6D (DIGIC 5+), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the M100 offers a higher resolution of 24 megapixels, compared with 20 MP of the 6D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 6.57μm for the 6D). However, it should be noted that the M100 is much more recent (by 4 years and 11 months) than the 6D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon M100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon 6D are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The M100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 6D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon EOS M100 are ISO 100 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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"). Of the two cameras under review, the 6D has a notably higher overall DXO score than the M100 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 0.8 EV of lower dynamic range, and 0.9 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the M100 provides a faster frame rate than the 6D. It can shoot movie footage at 1080/60p, while the 6D is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 6D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M100 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon 6D and Canon M100 along with similar information for a selection of comparators.

One feature that is present on the 6D, but is missing on the M100 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

Concerning the storage of imaging data, both the 6D and the M100 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Connectivity comparison

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 6D and Canon EOS M100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 6D has a hotshoe, while the M100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Travel and landscape photographers will find it useful that the 6D has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 6D and the M100 have been discontinued, but can regularly be found used on ebay. The 6D was replaced by the Canon 6D Mark II, while the M100 was followed by the Canon M200. Further information on the features and operation of the 6D and M100 can be found, respectively, in the Canon 6D Manual (free pdf) or the online Canon M100 Manual.

Review summary

So what conclusions can be drawn? Is the Canon 6D better than the Canon M100 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon EOS 6D:

• Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (0.9 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Longer lasting: Can take more shots (1090 versus 295) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• More heavily discounted: Has been available for much longer (launched in September 2012).

Advantages of the Canon EOS M100:

• More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
• More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
• 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).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (6.1 vs 4.5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (108x67mm vs 145x111mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 468g or 61 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (76 percent cheaper at launch).
• More modern: Reflects 4 years and 11 months of technical progress since the 6D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the M100 is the clear winner of the contest (17 : 10 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 when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Canon 6D and the Canon M100 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the 6D and the M100 in practical situations. 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

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, 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.
