An impressive lens line
The highly renowned HC/HCD lens line includes 11 Auto-Focus
lenses, all with central shutters. Range is from 28mm to 300mm,
50-110mm zoom, 35-90mm zoom and 1.7X converter. The HTS 1.5
tilt/shift adapter delivers an easy to use, portable tilt/shift solu-
tion for 5 HC/HCD lenses ranging from 28mm to 100mm. The CF
adapter (optional accessory) allows use of the classic CF-lenses
from the Hasselblad V System, with full use of their central shutters,
allowing ash 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 eect.
In this way
the full HC lens program is even further enhanced, bringing a new
level of sharpness and resolution.
Two modes of operation and storage
The H4D oers a storage choice of either CF cards or a direct com-
puter hard drive connection. With these two operating and storage
options, you are able to select a mode to suit the nature of the work
in hand, whether in the studio or on location.
True Focus
True Focus helps solve one of the most lingering challenges that
faces serious photographers today: true, accurate focusing through-
out the image eld. 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.
Ultra-Focus
Ultra-Focus allows information from the lens and exact capture
conditions to be fed to the camera processor for ultra-ne-tuning
of the auto-focus mechanism, taking into account the design spec-
ications of the lens and the optical specications of the sensor.
DAC
'Digital Auto Correction' (DAC), is an APO-chromatic correction
of the images based on a combination of the various parameters
concerning each specic lens for each specic shot, ensuring that
each image represents the best that your equipment can produce.
