Pentax 645D vs 645Z
The Pentax 645D and the Pentax 645Z are two professional cameras that were revealed to the public, respectively, in March 2010 and April 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a medium format sensor. The 645D has a resolution of 39.5 megapixels, whereas the 645Z 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 Pentax 645D 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.
The side-by-side display below illustrates the physical size and weight of the Pentax 645D and the Pentax 645Z. 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.
In this particular case, the Pentax 645D and the Pentax 645Z have exactly the same width and height, and, thus, have identically-sized bodies. However, the 645Z is markedly heavier (5 percent) than the 645D. 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 645Z was launched at a somewhat lower price (by 15 percent) than the 645D, which makes it more attractive for photographers on a tight budget. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a medium format sensor, but their sensors differ slightly in size. The sensor area in the 645Z is 1 percent smaller. They nevertheless have the same format factor of 0.79. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
Technology-wise, the 645Z uses a more advanced image processing engine (PRIME III) than the 645D (PRIME II), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the 645Z offers a higher resolution of 51.1 megapixels, compared with 39.5 MP of the 645D. 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 5.30μm versus 6.06μm for the 645D). However, it should be noted that the 645Z is much more recent (by 4 years and 1 month) than the 645D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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 Pentax 645D are 36.3 x 27.2 inch or 92.3 x 69.1 cm for good quality, 29.1 x 21.8 inch or 73.8 x 55.3 cm for very good quality, and 24.2 x 18.1 inch or 61.5 x 46.1 cm for excellent quality prints.
The Pentax 645D has a native sensitivity range from ISO 100 to ISO 1600. 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 assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the 645Z offers substantially better image quality than the 645D (overall score 19 points higher). The advantage is based on 1.4 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.

Many modern cameras cannot only take still pictures, but also record videos. The 645Z indeed provides for movie recording, while the 645D does not. The highest resolution format that the 645Z can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. The 645D 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 viewfinders of both cameras offer the same field of view (98%), as well as the same magnification (0.78x). The adjacent table lists some of the other core features of the Pentax 645D and Pentax 645Z along with similar information for a selection of comparators.

The Pentax 645D 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 645D and the 645Z write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The 645Z supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 645D cannot take advantage of Ultra High Speed SD cards.
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 Pentax 645D 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 645D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 645D was succeeded by the Pentax 645Z. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Pentax website.
So what conclusions can be drawn? Is the Pentax 645D better than the Pentax 645Z or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Pentax 645D:
- Longer lasting: Can take more shots (800 versus 650) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in March 2010).
Advantages of the Pentax 645Z:
- More detail: Has more megapixels (51.1 vs 39.5MP), which boosts linear resolution by 14%.
- Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.4 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).
- Better jpgs: Has a more modern image processing engine (PRIME III vs PRIME II).
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 921k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (3 vs 1.1 flaps/sec) to capture the decisive moment.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was released into a lower priced segment (15 percent cheaper at launch).
- More modern: Reflects 4 years and 1 month of technical progress since the 645D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the 645Z is the clear winner of the contest (15 : 2 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 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.
How about other alternatives? Do the specifications of the Pentax 645D 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 645D or the 645Z. 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
