Hasselblad X1D versus Pentax 645Z
The Hasselblad X1D-50c and the Pentax 645Z are two professional cameras that were officially introduced, respectively, in June 2016 and April 2014. The X1D is a mirrorless interchangeable lens camera, while the 645Z is a DSLR. Both cameras are equipped with a medium format sensor. The Hasselblad has a resolution of 51.3 megapixel, whereas the Pentax provides 51.1 MP.
An illustration of the physical size and weight of the Hasselblad X1D and the Pentax 645Z is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the X1D – represents 100 percent across all the size and weight measures).
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 larger (24 percent) than the Hasselblad X1D. Moreover, the 645Z is substantially heavier (114 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 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 645Z was somewhat cheaper (by 6 percent) than the X1D 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 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. 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.
Both cameras under consideration feature a medium format sensor, but their sensors differ slightly in size. 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.
With 51.3MP, the X1D offers a slightly higher resolution than the 645Z (51.1MP), but the X1D nevertheless has the same individual pixel size (pixel pitch of 5.30μm) as the 645Z due to its larger sensor. It is noteworthy in this context that the X1D is a somewhat more recent model (by 2 years and 2 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 pixels. 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.
Consistent information on actual sensor performance is available from DXO Mark for most 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 645Z provides a faster frame rate than the X1D. It can shoot movie footage at 1080/60i, while the Hasselblad is limited to 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 645Z 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 following table reports on some other key feature differences and similarities of the Hasselblad X1D, the Pentax 645Z, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the X1D and the 645Z are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The 645Z replaced the earlier Pentax 645D, while the X1D does not have a direct predecessor.
So what is the bottom line? Is there a clear favorite between the Hasselblad X1D and the Hasselblad X1D? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Hasselblad X1D-50c:
- 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.
- More compact: Is smaller (150x98mm vs 156x117mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 825g or 53 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- More prestigious: Has the Hasselblad luxury appeal, which ensures a high resale price.
- More modern: Reflects 2 years and 2 months of technical progress since the 645Z launch.
Reasons to prefer the Pentax 645Z:
- Better video: Provides higher movie framerates (1080/60i vs 1080/25p).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Has 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.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 920k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (3 vs 2.3 flaps/sec) to capture the decisive moment.
- 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 645Z emerges as the winner of the match-up (9 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
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 handling experience and imaging performance when actually working with the X1D or the 645Z. 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 hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
