Hasselblad 1000 F, User Manual

Page: 44 / 64

THE PRISM SPORTS FINDER fits into the grooves above the ground glass in place of the reflex hood. It is made of stainless steel and
light alloy. It has two sighting apertures. The first is for looking straight ahead through the front frame to observe and follow the
subject. The second eyepiece is directed down at approximately 25 degrees into a tube. At the end of the latter there is a pentaprism
above a small rectangular centre-section of the reflex ground glass screen. This permits focusing and control of the depth of field while
the camera follows the subject. The tube is adjustable and marked for parallax correction. The front frame has a spring-loaded holder
for interchangeable masks. A mask for the 2¼ x 2¼ in. negative size is supplied with the finder. Separate masks for the 16 and 16S
magazines are available. Each mask has in its centre a polarized disc which appears blacked out if the eye is not in a straight line with
the front frame.
THE TIRAC SPORTS FINDER is a simplified version of the above sports finder. It is suitable for the model 500C. It has parallax
correction but no reflex focusing prism, and it can be folded flat. The film fits into the accessory shoe. The metal frame is used as a
mask for the standard 80-mm. Planar lens with the 2¼ x 2¼ in. magazine. Masks for different picture sizes and lens fields slide into
the grooved metal frame.
THE SPORTS FINDER F is of similar design to the Tirac, but for the 1600F and 1000F. The base contains the flash socket for either the
U.S. or the standard 3-mm. co-axial flash plug.
THE FRAME FINDER TISFC shows the field of the 150-mm. and 250-mm. lenses and clips to the front of the lens hood.
The Ground Glass Adapter
A ground glass adapter can be attached to the back of the Super Wide models in the same way as a magazine. When working from a
tripod, the ground glass screen permits visual observation of the image, for easy composition, alignment of vertical lines and control of
depth of field. The screen is fitted with a Fresnel lens for brighter images.
The ground glass adapter can be combined with the magnifying hood or the standard reflex hood of any of the other Hasselblad
models.
ALTERNATIVE FINDER UNITS
To remove the standard hood (left), first release the magazine 6 and then slide the hood backwards out of its grooved fitting.
Alternative finders, such as the magnifying hood (right) can then be slid in place.
To fit the pentaprism, first remove the sheath from the bottom of the pentaprism which protects the optical glass surfaces. Mount
the pentaprism on the top of the camera in the same way as the standard hood (left). Alternatively the prism frame finder (now
discontinued) can be fitted on the top of the camera. This simultaneously provides a view of the focusing screen and a direct eye-
level view through the frames of the finder. Interchangeable masks are available for the finder frame to indicate the fields of view
with the different lenses (right).
