Pentax 645Z versus Hasselblad X1D

The Pentax 645Z and the Hasselblad X1D-50c are two professional cameras that were announced, respectively, in April 2014 and June 2016. The 645Z is a DSLR, while the X1D is a mirrorless interchangeable lens camera. Both cameras are equipped with a medium format sensor. The Pentax has a resolution of 51.1 megapixel, whereas the Hasselblad provides 51.3 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Pentax 645Z vs Hasselblad X1D

The physical size and weight of the Pentax 645Z and the Hasselblad X1D 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 measures are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 645Z – 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 Hasselblad X1D is notably smaller (19 percent) than the Pentax 645Z. Moreover, the X1D is substantially lighter (53 percent) than the 645Z. 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. The listed launch 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. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Pentax 645Z vs Hasselblad X1D

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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. 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.

Pentax 645Z and Hasselblad X1D sensor measures

With 51.3MP, the X1D offers a 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. Moreover, the X1D is a much more recent model (by 2 years and 2 months) than the 645Z, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

645Z versus X1D MP

Consistent information on actual sensor performance is available from DXO Mark for many 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 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 645Z provides a higher frame rate than the X1D. It can shoot video footage at 1080/60i, while the Hasselblad is limited to 1080/25p.

 

Feature comparison: Pentax 645Z vs Hasselblad X1D

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 Pentax 645Z, the Hasselblad X1D, and comparable cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that is present on the 645Z, but is missing on the X1D is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

Both the 645Z and the X1D 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.

Review summary: Pentax 645Z vs Hasselblad X1D

So what conclusions can be drawn? Is there a clear favorite between the Pentax 645Z and the Hasselblad X1D? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Hasselblad X1D-50c:

  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More compact: Is smaller (150x98mm vs 156x117mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 825g or 53 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More prestigious: Has the Hasselblad luxury appeal, which ensures a high resale value.
  • More modern: Reflects 2 years and 2 months of technical progress since the 645Z launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 645Z emerges as the winner of the contest (9 : 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.

645Z 09:07 X1D

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 645Z or the X1D handle or 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 why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
