Hasselblad has refined the concept of high-end full-frame dSlR cameras. this model complements the top end models with multi-shot functionality: the ultimate choice for still life studio photography. Moiré free images that exhibit a level of sharp- ness, resolution and color fidelity that you have to experience to believe are now attainable. this capability incorporated with the unparalleled abilities of the H4d produce an unbeatable combination in the world of digital medium format photogra- phy today. the H4d-50MS includes UltraFocus architecture and offers access to HCd 28mm lens, designed and optimized solely for digital image capture. Phocus software puts the final
touches to files by using digital auto Correction. this feature utilizes automatic correction for chromatic aberration, distortion and vignetting for breathtaking results. it is not surprising that internationally renowned museums and art galleries around the world put their trust in the H4d-50MS for the faithful documen- tation of their collections.
With its large and bright viewfinder image, wide range of quality lenses and broad choice of accessories, the H4d-50MS also serves as an ultra capable camera for more everyday demands.
Non-compromising details and colors
the multi-shot technology realizes the capture of still life subjects with all details represented in true detail and color resolution. By capturing a sequence of 4 shots, each offset by a one pixel incre- ment, every point on your set is rendered with its true red, green and blue color components. in this way, true detail and true color are acquired without interpolation of any kind. For stills photography it simply does not get better.  When used outdoors or on location, the H4d-50MS can perform normal single-shot mode photography too.
Ultra-Focus and Digital Auto Correction for image perfection
Using the Ultra-Focus engine of H4d-50MS the full H system lens program is further enhanced, bringing a new level of sharpness
and resolution. the digital lens Correction (daC) will automatically remove any chromatic aberration, distortion and vignetting when images are processed using Phocus. the design of the HCd 28mm and 35-90mm lenses have been opti- mized for the actual 36,7×49mm area of the sensor to make it more compact and to work in conjunction with daC.  The highly renowned H system lens line uses central lens shutters, which adds flexibility by allowing flash to be employed at shutter speeds up to 1/800s. the central shutter also improves image quality by reducing camera vibration. and thanks to the large format of the H System cameras, there is a considerably shallower depth of field range, making it much easier to utilize selective focus to creative effect.
View-camera work
the H4d-50MS has been designed to allow the digital capture unit to be detached and used on a view camera by way of an H system adapter. in this configuration the digital capture device can work with electronic shutters from e.g. Rollei and Schneider, either stand-alone using the flash sync signal from the shutter or tethered to a com- puter with full control of the electronic shutter from the computer.
Medium Format digital capture
In digital photography, the advantages of larger format cameras have become even more obvious. the 6×4.5 cm window allows the Hasselblad H4d-50MS to use one of the largest image sensors currently available in digital photography – up to more than twice the size of a 35mm camera sensor. Consequently the sensor holds more and larger pixels, which deliver the highest possible image quality in terms of moiré-free color rendering without gradation break-ups in even the finest lit surfaces.
Unique Hasselblad Colors
Hasselblad Natural Color Solution (HNCS) enables you to produce outstanding and reliable out-of-the-box colors, with skin tones, spe- cific product colors and other difficult tones reproduced easily and effectively.
Phocus for professional level workflow
Phocus provides an advanced software toolbox that has been especially designed to achieve optimum workflow and absolute image perfection from Hasselblad raw image files.
With the H4D-50MS camera system Phocus provides:
   • Uncompromising Image Quality
   • Special extended camera controls with which to operate your
H4d-50MS camera. these features, such as live video for easier shot set-up and workflow, or the ability to control the lens drive for focusing when the camera is in a remote position or when the digital capture unit is mounted on a view camera, bring an entirely new level of flexibility to the way you shoot.
   • Moiré Removal Technology automatically applied directly on the raw data, leaving image quality intact and eliminating the need to carry out special masking selections or other manual procedures, saving hours of tedious post-production work.
   • Flexible Workflow. The Phocus gUi features easy-to-use options that allow you to customize your set-up to suit a range of dif- ferent workflow situations, such as choice of import source, browsing/comparison functions, file management, image export in a number of file formats, pre-setting of options for upcoming shoots, and much, much more.
  • The extended metadata (GPS, HTS 1.5 etc) included in all Phocus images provides for accurate and detailed cataloging and indexing, easy image management, and includes added gPS data functional- ity in order to allow a range of new functions. Phocus links gPS data directly to google Earth, for example, making geographic reference a snap and image storage and retrieval much easier. With the HtS 1.5, all settings are stored as metadata in the image file for full function with daC lens corrections.
  • Perfect Viewing Quality. The Phocus Viewer delivers image viewing quality that matches every detail of what you will see later in Pho- toshop. in addition, the Phocus Viewer allows you to customize layout and composition to suit your current or desired work flow, providing a wide range of options including full view, compare, browse, horizontal, or vertical view, and so on. You can have multiple folders open simultaneously for side-by-side viewing, comparison, and selection.
Electronic spirit level
The H4d-50MS has an integrated electronic spirit level to make it easy to produce a straight horizon. the spirit level is shown both in the viewfinder and on the rear lCd. You therefore don’t need to take your eye from the viewfinder to check camera alignment.
Camera info on rear LCD
To improve visibility in certain situations, the rear lCd can now show a copy of the camera grip lCd where you see all relevant shooting information.

True Focus and Absolute Position Lock.
True Focus helps solve one of the most lingering challenges that faces serious photographers today: true, accurate focusing through- out the image field. Without multi-point auto-focus a typical auto- focus camera can only correctly measure focus on a subject that is in the center of the image. When a photographer wants to focus on a subject outside the center area, they have to lock focus on the subject and then re-compose the image. in short distances espe- cially, this re-composing causes focus error, as the plane of focus sharpness follows the camera’s movement, perpendicular to the axis of the lens.
The traditional solution for most dSlR cameras has been to equip the camera with a multi-point aF sensor. these sensors allow the photographer to fix an off-center focus point on an off-center sub- ject, which is then focused correctly. Such multi-point aF solutions are often tedious and inflexible to work with. due to the physics of an SlR-camera, the off-center focus points that are offered are all clustered relatively close to the center of the image. to set focus outside of this center area, the photographer is still forced to focus first, and then shift the camera to reframe, with the resulting loss of focus as a result.
to overcome this problem, Hasselblad has used modern yaw rate sensor technology to measure angular velocity in an innovative way. the result is the new absolute Position lock (aPl) processor, which forms the foundation of Hasselblad’s true Focus feature.
The aPl processor accurately logs camera movement during any re-composing, then uses these exact measurements to calculate the necessary focus adjustment, and issues the proper commands to the lens’s focus motor so it can compensate. the aPl processor computes the advanced positional algorithms and carries out the required focus corrections at such rapid speed that no shutter lag occurs. the H4d’s firmware then further perfects the focus using the precise data retrieval system found on all H System lenses.
