Basic ISO rating is from ISO 50 to ISO 400. Using H3DII-39 with
Hasselblad’s Phocus software, the ISO can be bumped further to ISO
800. As with its fellow H3DII models, the H3DII-39 makes use of a
new high speed capture architecture capturing full size, compressed
50 Mbyte images at the rate of 1.4 seconds per capture, working
either mobile or tethered to a computer.

The combination of these features makes the H3DI-39 the natural
choice for the professional commercial photographer working both
studio and location with the highest ambitions for creative expres-
sion and the need to deliver only the best image quality to a range
of extremely demanding customers.

Medium Format digital capture advantage

In digital photography, the advantages of large format cameras have
become even more obvious. The 6×4.5 cm window allows the H3DII-39
to use one of the largest image sensors currently available in digital
photography – more than twice the physical 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.

An impressive lens line

The highly renowned HC/HCD lens line includes 10 Auto-Focus lenses,
all with central shutters. Range is from 28mm to 300mm, 50-110mm
zoom, and 1.7X converter. The HTS 1.5 tilt/shift adapter delivers an
easy to use, portable tilt/shift solution for 4 HC/HCD lenses rang-
ing from 28mm to 80mm. the CF adapter allows use of the classic
CF-lenses from the Hasselblad V-camera, with full use of their cen-
tral shutters, 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 cam-
eras, there is a considerably shallower depth of field range, making it
much easier to utilize selective focus to creative effect.

A choice of large and bright viewfinders

One of the important traditional advantages of the medium format is
the extra-large and bright viewfinder image, enabling extremely pre-
cise compositions and easy operation in dim lighting. the H3dii-39
comes with the HVD 90x viewfinder designed for full performance over
the large 36x48mm sensor. Hasselblad has added an interchange-
able waist-level viewfinder, the HVM, for the entire range of H system
cameras. The bright and large viewfinder image is ideal for creative
composing and the photographer is able to shoot in the fashion that
suits them most; maintaining eye contact with the model, or gaining
impact by shooting from a point lower than eye-level, for example.
