Lens Characteristics and Specifi cations
249
Distagons are retrofocus-type wide angle lenses with a long back focus for use on SLR
cameras. The Biogon is an optically true wide angle design. Variogon is the trade name for
the zoom lens made by Schneider. The 60–120 mm zoom lens is designed by Hasselblad and
manufactured to Hasselblad’s specifi cations and tolerances.
Lenses for the H Camera System
All lenses for the H camera system are made by Fuji in Japan in cooperation with the Hasselblad
lens designers. The lenses are manufactured to the highest standards specifi ed by Hasselblad
with all the glass and air surfaces multicoated to produce the most satisfactory image quality in
digital and fi lm photography. Some of the lens designs are shown in Figure 14-15.
All lenses for the H camera system have shutters designed by Hasselblad with shutter
speeds up to 1/800 second. These shutters are designed in two different sizes in order to pro-
duce most accurate shutter speeds over the entire shutter speed range with any focal length
lens regardless of the physical diameter of the lens elements. Shutters with a 20 mm diameter
are built into lenses up to and including 80 mm focal length. The larger shutter with a 28 mm
diameter is in the longer focal length lenses.
Figure 14-12
Wide angle distortion. (1) A round subject at the edges (B) becomes elongated
when traced onto the fl at image plane. Distance (b) is greater than distance (a) for the round
subject in the center. (2) When you photograph groups of people or products, wide angle
distortion is further emphasized because the lens sees the subjects at the edges from the side
(B), but it sees those in the center from the front (A). You can greatly reduce the distortion
by turning the people or the products on the sides so that the lens also sees them from the
front (C).
