Hasselblad H4D-50MS V1 DATASHEET
DIGITAL CAMERAS
Hasselblad has rened the concept of high-end full-frame DSLR
cameras by introducing the H4D -50MS. This model comple-
ments the top end models with multi-shot functionality: the
ultimate choice for still life studio photography. Moiré free
images that exhibit a level of sharpness, resolution and color
delity that you have to experience to believe are now attain-
able. This capability incorporated with the unparalleled abilities
of the H4D produce an unbeatable combination in the world
of digital medium format photography today. The H4D-50MS
also includes UltraFocus architecture and offers access to the
latest HCD 28mm lens, designed and optimized solely for digital
image capture. Phocus software puts the nal touches to les
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 documentation of their
collections.
With its large and bright view nder 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 cap-
turing a sequence of 4 shots, each offset by a one pixel increment,
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 HC/HCD 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 36×48mm area of the sensor to make it more
compact and to work in conjunction with DAC.
The highly renowned HC/HCD lens line uses central lens shutters,
which adds exibility by allowing ash 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 eld 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 conguration the digital capture device can work with
electronic shutters from e.g. Rollei and Schneider, either stand-alone
using the ash 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 nest lit surfaces.
A choice of bright viewfinders
One of the important traditional advantages of the medium format
is the extra-large and bright viewnder image, enabling extremely
precise compositions and easy operation in dim lighting. An inter-
changeable waist-level viewnder, the HVM, is available for the
entire range of H system cameras.
Unique Hasselblad Colors
The new Hasselblad Natural Color Solution (HNCS) enables you to
produce outstanding and reliable out-of-the-box colors, with skin
tones, specic product colors and other difcult tones reproduced
easily and effectively.
GPS recording accessory
Hasselblad’s Global Image Locator (GIL) is an accessory for any
H-based Hasselblad digital capture product. Using the GIL device all
images captured outdoors are tagged with GPS coordinates, time and
altitude. This data is key to a number of future applications involving
image archiving and retrieval. One example is the direct mapping of
images within the coming Phocus software to Google Earth.
Modes of operation and storage
The Hasselblad H4D-50MS offers a choice of storage devices: CF
cards or a computer hard drive. With these two operating and stor-
age options, you are able to select a mode to suit the nature of the
work in hand, whether in the studio or on location.
Phocus for professional level workflow
Phocus provides an advanced software toolbox that has been
especially designed to achieve optimum workow and absolute
image perfection from Hasselblad raw image les.
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 workow, 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 exibility 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 Workow. The Phocus GUI features easy-to-use options
that allow you to customize your set-up to suit a range of dif-
ferent workow situations, such as choice of import source,
browsing/comparison functions, le management, image export
in a number of le formats, pre-setting of options for upcoming
shoots, and much, much more.
• New Metadata (GPS, HTS 1.5 etc). The extended metadata
included in all Phocus images provides for accurate and detailed
cataloging and indexing, easy image management, and includes
added GPS data functionality 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 stor-
age and retrieval much easier. With the HTS 1.5, all settings are
stored as metadata in the image le for full function with DAC
lens corrections.
• Perfect Viewing Quality. The Phocus Viewer delivers image view-
ing quality that matches every detail of what you will see later
in Photoshop. In addition, the Phocus Viewer allows you to
customize layout and composition to suit your current or desired
work ow, 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
v iewing, comparison, and selection.

Single Shot
The key to the single shot quality from a CCD sensor is due to the
use of a Bayer Mosaic lter. This is a specic layout that is used
in conjunction with software to interpret the colour data from the
sensor. A single-shot system delivers one colour per pixel, and the
remaining two channels must be estimated and calculated using a
bestguess strategy. This is done in Hasselblad cameras by using
algorithms that optimize colour rendition and sharpness without
disturbing the perception of the human eye by the artefacts always
present in raw single shot captures.

Multi Shot
High precision piezo motors control movements of the sensor
in one pixel increments. By combining four shots, each offset by
one pixel, the true colours, Red, Green and Blue of each point are
obtained. The result is full colour information from the sensor with
no artefacts like moiré, common with single shot capture.
