Hasselblad X1D II vs Sony A1
The Hasselblad X1D II 50C and the Sony A1 are two professional cameras that were officially introduced, respectively, in June 2019 and January 2021. Both the X1D II and the A1 are mirrorless interchangeable lens cameras that are based on a medium format (X1D II) and a full frame (A1) sensor. The Hasselblad has a resolution of 51.3 megapixels, whereas the Sony provides 49.8 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 II 50C and the Sony A1? 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 Hasselblad X1D II and the Sony A1. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A1 is notably smaller (13 percent) than the Hasselblad X1D II. Moreover, the A1 is slightly lighter (4 percent) than the X1D II. 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 battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 X1D II was launched at a somewhat lower price (by 12 percent) than the A1, 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 size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Hasselblad X1D II features a medium format sensor and the Sony A1 a full frame sensor. The sensor area in the A1 is 40 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.0. The sensor in the X1D II has a native 4:3 aspect ratio, while the one in the A1 offers a 3:2 aspect.
With 51.3MP, the X1D II offers a slightly higher resolution than the A1 (49.8MP), but the X1D II nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 4.16μm for the A1) due to its larger sensor. However, the A1 is a somewhat more recent model (by 1 year and 7 months) than the X1D II, and its sensor might have benefitted from technological advances during this time that 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.
The A1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the X1D II, the A1 has the capacity to capture high quality composite images (YESMP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Hasselblad X1D II 50C has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Sony A1 are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 500-102400.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). 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 can also record movies. The A1 indeed provides for movie recording, while the X1D II does not. The highest resolution format that the A1 can use is 8k/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A1 offers a substantially higher resolution than the one in the X1D II (9437k vs 3690k dots). The following table reports on some other key feature differences and similarities of the Hasselblad X1D II, the Sony A1, and comparable cameras.

One feature that differentiates the A1 and the X1D II is in-body image stabilization (IBIS). The A1 reduces the risk of handshake-induced blur with all attached lenses, while the X1D II offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Hasselblad X1D II and the Sony A1 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.
The X1D II writes its imaging data to SDXC cards, while the A1 uses CFexpress or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.
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 II 50C and Sony A1 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.
Travel and landscape photographers will find it useful that the X1D II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
Both the X1D II and the A1 are recent models that are part of the current product line-up. The X1D II replaced the earlier Hasselblad X1D, while the A1 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Hasselblad and Sony websites.
So how do things add up? Which of the two cameras – the Hasselblad X1D II or the Sony A1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Hasselblad X1D II 50C:
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.

- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 2.7 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (129x97mm vs 148x97mm) and will fit more readily into a bag.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Was introduced somewhat (1 year and 7 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the A1 emerges as the winner of the match-up (12 : 10 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 II and the Sony A1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the X1D II and the A1 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is where reviews by experts come in. 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 review scores listed above should be treated 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
