Hasselblad X1D vs Pentax 645D
The Hasselblad X1D-50c and the Pentax 645D are two professional cameras that were announced, respectively, in June 2016 and March 2010. The X1D is a mirrorless interchangeable lens camera, while the 645D is a DSLR. Both cameras are equipped with a medium format sensor. The Hasselblad has a resolution of 51.3 megapixels, whereas the Pentax provides 39.5 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 Hasselblad X1D-50c and the Pentax 645D? 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 Hasselblad X1D and the Pentax 645D 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 size 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 645D is notably larger (24 percent) than the Hasselblad X1D. Moreover, the 645D is substantially heavier (104 percent) than the X1D. 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 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 X1D was somewhat cheaper (by 10 percent) than the 645D at launch, but both cameras fall into the same price category. 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 size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature a medium format sensor, but their sensors differ slightly in size. The sensor area in the 645D is 1 percent bigger. 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.
Despite having a slightly smaller sensor, the Hasselblad X1D offers a higher resolution of 51.3 megapixels, compared with 39.5 MP of the Pentax 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 X1D is much more recent (by 6 years and 3 months) 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 Hasselblad X1D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X1D for good quality output (200 dots per inch) amounts to 41.4 x 31 inches or 105.1 x 78.7 cm, for very good quality (250 dpi) 33.1 x 24.8 inches or 84 x 63 cm, and for excellent quality (300 dpi) 27.6 x 20.7 inches or 70 x 52.5 cm. The corresponding values for the Pentax 645D are 36.3 x 27.2 inches or 92.3 x 69.1 cm for good quality, 29.1 x 21.8 inches or 73.8 x 55.3 cm for very good quality, and 24.2 x 18.1 inches or 61.5 x 46.1 cm for excellent quality prints.
The Hasselblad X1D-50c has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Pentax 645D are ISO 100 to ISO 1600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 review, the X1D provides substantially higher image quality than the 645D, with an overall score that is 20 points higher. This advantage is based on 1.6 bits higher color depth, 2.2 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 are not only capable of taking still images, but can also record movies. The X1D indeed provides movie recording capabilities, while the 645D does not. The highest resolution format that the X1D can use is 1080/25p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the X1D has an electronic viewfinder (2360k dots), while the 645D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Hasselblad X1D and Pentax 645D 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 X1D has a touchscreen, while the 645D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The Hasselblad X1D and the Pentax 645D 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 X1D and the 645D write their files to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The X1D 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 Hasselblad X1D-50c and Pentax 645D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X1D offers wifi support, while the 645D does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the X1D and the 645D have been discontinued, but can regularly be found used on eBay. The 645D was replaced by the Pentax 645Z, while the X1D was followed by the Hasselblad X1D II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Hasselblad and Pentax websites.
So what conclusions can be drawn? Is the Hasselblad X1D better than the Pentax 645D or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Hasselblad X1D-50c:
- More detail: Offers more megapixels (51.3 vs 39.5MP) with a 14% higher linear resolution.
- Better image quality: Scores substantially higher (20 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.6 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (2.2 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1.8 stops ISO advantage).
- Broader imaging potential: Can record not only still images but also 1080/25p movies.
- More framing info: Has an electronic viewfinder that displays shooting data.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (2.3 vs 1.1 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (150x98mm vs 156x117mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 755g or 51 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More prestigious: Has the Hasselblad luxury appeal, which ensures a high resale price.
- More modern: Reflects 6 years and 3 months of technical progress since the 645D launch.
Advantages of the Pentax 645D:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More heavily discounted: Has been around for much longer (launched in March 2010).
If the count of relative strengths (bullet points above) is taken as a measure, the X1D is the clear winner of the match-up (17 : 4 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 Hasselblad X1D and the Pentax 645D 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X1D or the 645D. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
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], 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
