The sports viewfinder (left) fits into the shoe in the side of the camera. This finder again can be fitted with interchangeable masks
for lenses of different focal length. A special version indicates the fieId of view for the Sonnar 150 and 250 lenses used with
Hasselblads 500C/500EL and magazines A12, 12, 24 or 70.
The Super Wide C can also be used with a ground glass adaptor (right) to permit precise focusing on a ground glass screen. The
adaptor fits in place of the film magazine, and can be used with the focusing magnifier for accurate judgement of the screen image.

CLOSE-UP EQUIPMENT

The Hasselblad camera is particularly suitable for close-up photography as the actual picture is seen on the ground glass screen right
up to the moment of exposure. This eliminates all parallax and focusing errors. Any of the Hasselblad lenses can be used for close-ups.
Without the aid of any attachments the 80-mrn. Planar focuses down to 3 ft. At this distance the lens covers an area of 19 3/4 x 19
3/4 in. With the 60-, 150- and 250-mm. lenses at their closest setting the field covered is even somewhat less (see table on page 63).
If smaller areas are to be photographed, there are various close-up accessories.

Proxar Lenses

These are Zeiss close-up lenses in double bayonet mounts for series attachments (adding further a Proxar lens or/and a filter). They fit
the front of the 80-mm. Planar f2.8 lens. There are three types: Proxar 1.0 (focusing range 22 7/16 to 42½ in.), Proxar 2.0 (26 2/3
to 83 3/4 in.), and Proxar 0.5 (17¼ to 24¼ in.). They can be used singly or in combination.
When working with close-up lenses, stop down the camera lens to at least f 4 or f 5.6, to avoid falling-off of definition towards the
corners. No change of exposure time is required.

Extension Tubes

These go between the lens and the camera body. They increase the lens-to-film distance and thus enable the lens to focus on much
closer distances.
FOR THE HASSELBLAD 500C two extension tubes are available. One is 21 mm. long (M21) and one 55 mm. (M55). They have bayonet
front and rear fittings to suit the 500C body and lenses. A shaft passes through the extension tube to connect the camera lens with
the mechanism of the body, thus permitting the same automatic aperture control as without extension tubes. They can be used in
conjunction with any of the Hasselblad 500C lenses. For instance, with the 80-min. lens and the M21 tube the focusing range covers
subject-film distances from 40.2 to 48.5 cm.; with the 80-mm. lens and the M55 tube, from 31.9 to 32.6 cm.
With the standard 80-mm. Planar lens, extension tubes can also be used in conjunction with the Proxar lenses.
Before fitting the extension tubes fully wind the film transport and remove the lens. Attach the tube first to the camera body, and the
the lens to the tube. If two tubes are used, first fit the M21 to the camera body, the M55 tube to the M21 tube, and finally the lens to
the front of the combination of tubes.
To remove the extension tube or tubes, first remove the lens from the extension tube, releasing it with the extension tube release
button. Then remove the extension tubes, one at a time, starting with the route tube.
FOR THE HASSELBLAD F MODELS two tubes are provided. One is 20 mm. long (No. 20) and one 40 mm. (No. 40). They are threaded
to fit the camera body on one end and the lens on the other. They are suitable for all Hasselblad 1600F and 1000F lenses and can be
used individually or in combination.

CLOSE UP GEAR

Extension tubes are available for the Hasselblad to go between the
camera and the lens and shutter unit of the 500C. The tubes can be used
with any of the lenses. and incorporate a coupling shaft to con. nect the
