Canon 1D vs Pentax 645Z
The Canon EOS-1D and the Pentax 645Z are two professional cameras that were revealed to the public, respectively, in September 2001 and April 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D) and a medium format (645Z) sensor. The Canon has a resolution of 4.1 megapixels, whereas the Pentax provides 51.1 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-1D 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.
An illustration of the physical size and weight of the Canon 1D and the Pentax 645Z is provided in the side-by-side display below. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax 645Z is notably smaller (26 percent) than the Canon 1D. Moreover, the 645Z is slightly lighter (2 percent) than the 1D. 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 1D gets 500 shots out of its NP-E3 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 1D has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 1D was launched at a somewhat lower price (by 24 percent) than the 645Z, which makes it more attractive for photographers on a tight budget. 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.
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. 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 features an APS-H sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 162 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 0.79. The sensor in the 1D has a native 3:2 aspect ratio, while the one in the 645Z offers a 4:3 aspect.
With 51.1MP, the 645Z offers a higher resolution than the 1D (4.1MP), but the 645Z has smaller individual pixels (pixel pitch of 5.30μm versus 11.56μm for the 1D). Yet, the 645Z is a much more recent model (by 12 years and 6 months) than the 1D, 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 1D are 12.5 x 8.3 inches or 31.7 x 21.1 cm for good quality, 10 x 6.6 inches or 25.4 x 16.9 cm for very good quality, and 8.3 x 5.5 inches or 21.1 x 14.1 cm for excellent quality prints.
The Canon EOS-1D has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Pentax 645Z are ISO 100 to ISO 204800 (no boost).
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"). 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. The 645Z indeed provides for movie recording, while the 1D does not. The highest resolution format that the 645Z can use is 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. The 1D 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 1D 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 0.55x), 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 and Pentax 645Z along with similar information for a selection of comparators.

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 1D writes its imaging data to Compact Flash cards, while the 645Z uses SDXC cards. The 645Z features dual card slots, which can be very useful in case a memory card fails. In contrast, the 1D only has one slot.
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 and Pentax 645Z and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
The 645Z is a recent model that features in the current product line-up of Pentax. In contrast, the 1D has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1D was succeeded by the Canon 1D Mark II. 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.
So what is the bottom line? Which of the two cameras – the Canon 1D or the Pentax 645Z – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS-1D:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
- Faster shutter: Has higher mechanical shutter speed (1/16000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (8 vs 3 flaps/sec) to capture the decisive moment.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in September 2001).
Arguments in favor of the Pentax 645Z:
- More detail: Has more megapixels (51.1 vs 4.1MP), which boosts linear resolution by 244%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Is equipped with a larger and more technologically advanced sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.55x).
- Larger screen: Has a bigger rear LCD (3.2" vs 2.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 120k dots).
- 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 156x158mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (650 versus 500) out of a single battery charge.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More modern: Reflects 12 years and 6 months of technical progress since the 1D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the 645Z is the clear winner of the contest (16 : 7 points). 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 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 1D 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 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 1D 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.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 review scores listed above should be treated 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
