THE 50-mm. ZEISS DISTAGON f 4 is a wide-angle lens with an angle of view of 75 degrees (as compared with 52 degrees of the
standard lens). It consists of seven elements, has a focusing range from 20 in. to infinity and apertures f 4 to f 22. The lens accepts
series 63 filters. This lens has replaced the 60-mm. lens.
THE 60-mm. ZEISS DISTAGON f 4 (up to 1961 it was supplied with aperture f 5.6) is a wide-angle lens. The angle of view of this lens
is 67 degrees. It consists of seven elements, has focusing range of 21 in. to infinity and apertures from f 4 (or f 5.6) to f 22 The lens
accepts Hasselblad filters series 63.
THE 80-mm. ZEISS PLANAR f 2.8 is the standard lens of the Hasselblad 500C camera. It is a seven-element construction (originally
six-element) with an angle of view of 52 degrees, a focusing range from 3 ft. to infinity, and apertures from f 2.8 to f 22. The near
focusing limit can be extended by Proxar lenses, extension tubes, and the extension bellows ( ** ). This lens accepts Hasselblad filters,
series 50 with bayonet mount, and a series 80 bayonet lens hood. For infra-red film use a position 9.5 mm. to the right of the central
distance indication line as the focusing index.
THE 100 mm. f 3.5 ZEISS PLANAR has a particularly flat field (for photogrammetric use), is a slightly longer than normal length lens of
seven-element construction, with an angle of view of 43 degrees and a focusing range from 3 ft. to infinity and apertures from f 3.5 to
f 22. Intended for use specially calibrated together with camera body and magazine 70.
THE 105 mm. f 4.3 ZEISS UV SONNAR. This is a seven-element construction with an angle of view of 40 degrees and a focusing range
from 6 ft. to infinity. Apertures from f 4.3 to f 32. Available to special order only with enhanced UV transmission for use with UV
materials by scientists and technologists, especially when examining old or altered documents, etchings, tapestries, paintings, finger
prints on various surfaces, etc.
THE 120-mm. ZEISS S-PLANAR f 5.6 is a long focus lens giving 1.5 x magnification as compared with the standard lens. It is a six
element construction and has an angle of view of 36 degrees. The focusing range extends from 3 ft. to infinity and apertures are f 5.6
to f 32. The lens accepts series 50 filters with bayonet mount. For near focusing distances extension tubes ( ** ) and extension bellows
are available.
THE 150-mm. ZEISS SONNAR f 4 is the most universal long-focus lens, giving almost 2x magnification as compared with the standard
lens. It is a five-element construction, and has an angle of view of 29 degrees The focusing range extends from 5 ft. to infinity, and
apertures from f4 to f32. For near focusing distances extension tubes ( ** ) and extension bellows are available. This lens accepts
Hasselblad filters series 50 with bayonet mount and a 150/250 bayonet lens hood. For infra-red film use a position 4.2 min. to the
right from the central distance indication line as the focusing index.
THE 250-mm. ZEISS SONNAR f 5.6 is a tele lens for close-ups of distant subjects. It yields more than 3 times magnification as
compared with the standard lens. It is a four-element construction, with an angle of view of 18 degrees, and has a focusing range
from 8 ft. to infinity. For nearer shots, extension tubes and the extension bellows can be used ( ** ). Apertures are adjustable from f
5.6 to f 45. This lens accepts Hasselblad filters series 50 with bayonet mount and the 150/250 bayonet lens hood. For infra-red film
use a position 5.1 mm. to the right from the central distance indication line as the focusing index.
THE 500-mm. ZEISS TELE TESSAR f8 is a tele lens tor extreme magnification. Its main applications include special jobs in press,
expedition and wild animal photography. It is the first extreme tele lens with Compur shutter and automatic aperture setting. It is a
five-element tele construction; the distance from the front lens element to the film plane is only 380 mm. It yields a linear
magnification of 6¼ times as compared with the standard tens, with an angle of view of 9 degrees. The focusing range is from 28 ft.
to infinity; the apertures are adjustable from f 8 to f 64. The lens accepts Hasselblad series 86 filters with threaded fitting and
threaded lens hood. The latter is supplied with the lens.
Changing the Lenses of the 500C
The lenses have a bayonet mount with four retaining lugs, and one starting point only.
REMOVING THE LENS. The shutter has to be tensioned before the lens can be removed. Depress the lens catch in the right bottom
corner of the front of the camera body, hold the entire lens mount with your right hand and turn it anti-clockwise by a one-fifth turn.
Then lift off the camera body.
FITTING THE LENS. A lens can only be attached to the camera when its shutter is tensioned. Normally, winding the film transport knob
tensions the shutter. With the lens removed from the camera, the groove on the tensioning shaft in the rear of the lens should then
point to the red mark beside it. If the shutter was released while the lens was removed from the camera it must be re-tensioned
before the lens can be inserted. The simplest way of tensioning the shutter is to place the edge of a coin in the groove on the cocking
shaft and turn clockwise.
The lens is in the correct position for attaching to the camera body when the red dot in the back of the lens is opposite the
corresponding mark on the camera body. Push lens into the flange of the body and turn the whole lens clockwise until the catch on
the bottom right-hand corner of the camera front clicks into position.
A LENS FLANGE designed for photographers who want to use the Hasselblad 500C lenses on their enlarger accepts the lens on one
side. while the other one will fit most enlargers. To stop down the Hasselblad lens when on the enlarger, use the manual aperture
setting lever.
