Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D X Mark II and the Pentax 645Z? 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 physical size and weight of the Canon 1D X Mark II and the Pentax 645Z are illustrated 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 dimensions are rounded to the nearest millimeter.

Size Canon 1D X Mark II vs Pentax 645Z
Compare 1DX Mark II versus 645Z top
Comparison 1DX Mark II 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 smaller (31 percent) than the Canon 1D X Mark II. However, the 645Z is slightly heavier (1 percent) than the 1DX Mark II. 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. 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 1DX Mark II gets 1210 shots out of its LP-E19 battery, while the 645Z can take 650 images on a single charge of its D-LI90 power pack. As can be seen in the images above, the 1DX Mark II has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 1DX Mark II was launched at a markedly lower price (by 29 percent) than the 645Z, 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

The size of the sensor inside a digital camera is one of the key determinants 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D X Mark II features a full frame sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 66 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 0.79. The sensor in the 1DX Mark II has a native 3:2 aspect ratio, while the one in the 645Z offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Canon 1D X Mark II and Pentax 645Z sensor measures

With 51.1MP, the 645Z offers a higher resolution than the 1DX Mark II (20MP), but the 645Z has smaller individual pixels (pixel pitch of 5.30μm versus 6.57μm for the 1DX Mark II). It is noteworthy in this context that the 1DX Mark II is a somewhat more recent model (by 1 year and 9 months) than the 645Z, and its sensor might have benefitted from technological advances during this time that further 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 inch or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inch or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inch or 69.9 x 52.4 cm. The corresponding values for the Canon 1D X Mark II are 27.4 x 18.2 inch or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inch or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inch or 46.3 x 30.9 cm for excellent quality prints.

The 1DX Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1D X Mark II has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-409600. The corresponding ISO settings for the Pentax 645Z are ISO 100 to ISO 204800 (no boost).

1DX Mark II versus 645Z MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 645Z offers substantially better image quality than the 1DX Mark II (overall score 13 points higher). The advantage is based on 1.9 bits higher color depth, 1.2 EV in additional dynamic range, and 0.5 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 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 1DX Mark II provides a higher video resolution than the 645Z. It can shoot video footage at 4K/60p, while the Pentax is limited to 1080/60i.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 1DX Mark II and the 645Z 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 viewfinder in the 1DX Mark II offers a wider field of view (100%) than the one in the 645Z (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 645Z has a higher magnification (0.78x vs 0.76x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 1D X Mark II and Pentax 645Z along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 1DX Mark II has a touchscreen, while the 645Z has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Pentax 645Z has 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.

The 1DX Mark II writes its imaging data to Compact Flash or CFast cards, while the 645Z uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

 

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-1D X Mark II and Pentax 645Z and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 1DX Mark II has a headphone jack, which is not present on the 645Z This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Travel and landscape photographers will find it useful that the 1DX Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 1DX Mark II and the 645Z are recent models that are part of the current product line-up. The 645Z replaced the earlier Pentax 645D, while the 1DX Mark II followed on from the Canon 1DX. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Pentax websites.

ilogo

Arguments in favor of the Pentax 645Z:

  • More detail: Has more megapixels (51.1 vs 20MP), which boosts linear resolution by 57%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.2 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.76x).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (156x117mm vs 158x168mm) and will fit more readily into a bag.
  • More heavily discounted: Has been on the market for longer (launched in April 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the 1DX Mark II emerges as the winner of the contest (14 : 11 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 1D X Mark II and the Pentax 645Z place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

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 1DX Mark II or the 645Z 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

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
