H4X
H4 features in abundance
The H4X is a marked step up for previous H1 and H2 owners. Many
of the features from the H4 line are included, not least, True Focus.
It is a very versatile model that allows the freedom of choice be-
tween using Hasselblad CF/CFH digital backs, third party digital
backs as well as Hasselblad film magazines. The H4X is therefore
a very serious contender in the medium format world that should
appeal to a broad spectrum of photographers.
An impressive lens line
The highly renowned HC/HCD lens line includes 11 Auto-Focus
lenses. The range is from 28mm to 300mm, 50-110mm zoom, 35-
90mm zoom and 1.7x converter. They all employ central shutters,
allowing flash to be employed at shutter speeds up to 1/500s. 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. In this way
the full HC/HCD lens program is even further enhanced, bringing
a new level of sharpness and resolution. (See under 'Lenses' for de-
tails about potential limitations concerning HCD lenses in combi-
nation with some digital/film backs).
True Focus
True Focus helps solve one of the most lingering challenges that
faces serious photographers today: true, accurate focusing through-
out the image field. The traditional solution for most DSLRs has been
to equip the camera with a multi-point AF sensor but it only resolves
some issues. To overcome this problem, Hasselblad has used modern
yaw rate sensor technology to measure angular velocity in an inno-
vative way. The result is the new Absolute Position Lock (APL) proces-
sor, which forms the foundation of Hasselblad's True Focus feature.
DAC (for CF/CFH users only)
Available with Hasselblad CF/CFH digital back use exclusively,
'Digital Auto Correction' (DAC), is an APO-chromatic correction
of the images based on a combination of the various parameters
concerning each specific lens for each specific shot, ensuring that
each image represents the best that your equipment can produce.
Optional Accessories
H system accessories include general items such as filters, straps
and lens shades etc., as well as specialist items such as the HTS 1.5
and the CF Adapter to really broaden your range. The HTS 1.5 tilt/
shift adapter (optional accessory) delivers an easy to use, portable
tilt/shift solution for five HC/HCD lenses ranging from 28mm to
100mm. The CF adapter (optional accessory) allows use of the clas-
sic CF-lenses from the Hasselblad V System. Have a look at the list
towards the end of this manual for more details.
Phocus
Hasselblad Phocus is the free RAW file processor to complete and
fine tune, primarily, Hasselblad raw (3FR) files from Hasselblad
digital backs. However it is capable of importing other raw formats
too, from a variety of manufacturers. You will find a copy of Phocus
on the included DVD, or you can download it directly from the
Hasselblad website.
Computer system requirements
Digital files naturally end up on a computer for processing.
Image-storage and correction requires a certain minimum
standard regarding computer capabilities. Large images will re-
quire a high-performance computer with plenty of memory, ad-
vanced graphics capabilities and a recent operating system. In
most cases, the computer should include a FireWire connector,
which will enable you to load images directly from the camera.
To load images stored on the removable compact-flash card,
you could instead use a compact-flash card reader, but FireWire
is recommended for maximum flexibility.
Warnings and restrictions
Keep the H4X and computer equipment away from mois-
ture wherever possible. If your camera becomes wet, dis-
connect from power and allow it to dry before attempt-
ing to operate again.
Always take great care when you remove a digital back
for cleaning as the exposed CCD sensor protective filter is
vulnerable to damage.
Keep all cables connected to or from your camera and
computer out of the way where they will not be tripped
over.
Please keep purchase details and the warranty in a safe
place.
Familiarise yourself with the various parts and compo-
nents. Leave protective covers on as much as possible
and avoid touching glass surfaces and inserting fingers
into the camera body. Hasselblad cameras have a ro-
bust construction and are capable of withstanding fairly
rough treatment but nevertheless are precision instru-
ments and will serve you longer if treated with respect
from the beginning.
Finally, please check occasionally on the Hasselblad
website – www.hasselblad.com – for any firmware and
software updates, news, tips, user manuals or other in-
formation.
