Body comparison

An illustration of the physical size and weight of the Canon M6 and the Pentax 645Z is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The M6 can be obtained in two different colors (black, silver), while the 645Z is only available in black.

Size Canon M6 vs Pentax 645Z
Compare M6 versus 645Z top
Comparison M6 or 645Z rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax 645Z is considerably larger (140 percent) than the Canon M6. Moreover, the 645Z is substantially heavier (297 percent) than the M6. It is noteworthy in this context that the 645Z is splash and dust-proof, while the M6 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 M6 gets 295 shots out of its Canon LP-E17 battery, while the 645Z can take 650 images on a single charge of its Pentax D-LI90 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M6 was launched at a markedly lower price (by 91 percent) than the 645Z, 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon M6 features an APS-C sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 333 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 0.79. The sensor in the M6 has a native 3:2 aspect ratio, while the one in the 645Z offers a 4:3 aspect.

Canon M6 and Pentax 645Z sensor measures

With 51.1MP, the 645Z offers a higher resolution than the M6 (24MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 3.72μm for the M6) due to its larger sensor. However, the M6 is a much more recent model (by 2 years and 10 months) than the 645Z, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the 645Z has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax 645Z implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 645Z for good quality output (200 dots per inch) amounts to 41.3 x 31 inches or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inches or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inches or 69.9 x 52.4 cm. The corresponding values for the Canon M6 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The M6 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS M6 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Pentax 645Z are ISO 100 to ISO 204800 (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.

M6 versus 645Z MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 645Z offers substantially better image quality than the M6 (overall score 23 points higher). The advantage is based on 2.6 bits higher color depth, 2.1 EV in additional dynamic range, and 1.8 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.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 645Z has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M6 relies on live view and the rear LCD for framing. That said, the M6 can be equipped with an optional viewfinder – the EVF-DC2. The following table reports on some other key feature differences and similarities of the Canon M6, the Pentax 645Z, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The M6 has one, while the 645Z does not. While the built-in flash of the M6 is not very powerful, it can at times be useful as a fill-in light.

The M6 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the 645Z does not have a selfie-screen.

The Canon M6 and the Pentax 645Z both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the M6 and the 645Z write their files to SDXC cards. The 645Z features dual card slots, which can be very useful in case a memory card fails. In contrast, the M6 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the M6 offers wifi support, while the 645Z does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Pentax 645Z (unlike the M6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the M6 and the 645Z have been discontinued, but can regularly be found used on ebay. The M6 was replaced by the Canon M6 Mark II, while the 645Z does not have a direct successor. Further information on the features and operation of the M6 and 645Z can be found, respectively, in the Canon M6 Manual (free pdf) or the online Pentax 645Z Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon M6 and the Pentax 645Z? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Canon EOS M6:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (9 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (112x68mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 1160g or 75 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • 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 (91 percent cheaper at launch).
  • More modern: Reflects 2 years and 10 months of technical progress since the 645Z launch.

ilogo

Arguments in favor of the Pentax 645Z:

  • More detail: Has more megapixels (51.1 vs 24MP), which boosts linear resolution by 43%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (23 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.8 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Longer lasting: Gets more shots (650 versus 295) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been around for much longer (launched in April 2014).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (15 points each). 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

M6 15:15 645Z

How about other alternatives? Do the specifications of the Canon M6 and the Pentax 645Z place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

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 M6 or the 645Z 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
