Close-Ups

Because the EXAKTA Varex is a single-lens reflex camera close-ups can be taken with it simply and easily. In accordance with optical laws the image distance ( = distance between lens and film plane) increases, when the subject distance ( = distance between lens and subject) decreases. Consequently, when focusing on a subject at a short distance from the camera, the distance between lens and film plane must be larger than attained by the helical focusing mount of the lens. Then extensions (bayonet rings and extension tubes) must be used. They are fitted in appropriate combinations, between lens and camera body. It is a characteristic of the single-lens reflex camera that there is no need for special optical attachments for focusing at short distances; the ground glass is used at all times for controlling of sharpness, depth of field, as well as for composing of the intended picture. The ground-glass screen image and the final picture are necessarily always identical and parallax, which often can not be eliminated at short distances, never exists with the EXAKTA Varex.

Two-in One Adapter Ring

For the minimum extension increase of 5 mm. a Two-in-One Ring is available. It is made as one piece. It fits into the camera after the lens is removed and is inserted into the front bayonet, so that the red dots on the lens mount and on the front part of the Two-in-One Ring come to stand opposite each other. By a short turn to the right the lens locks into the stop-lever, which catches with a click. To remove the lens from the Two-in-One Ring, press the little release button of the adapter ring and turn the lens to the left until the red dots are opposite each other again; then the lens can be removed from the adapter bayonet in the same manner as removing the lens from the camera. - Inserting the Two-in-One Ring into the camera is achieved in the same manner as attaching the lens alone. When the red dots on the camera and on the back part of the Two-in-One Ring are opposite each other, turn the adapter to the left, until the little lever on the camera snaps into position.

Front and Back Bayonet Adapter Rings and Extension Tubes

The next extension increase is of 10 mm. and is attached by the Pair of Bayonet Adapter Rings screwed together. Its handling is the same as that of the Two-in-One Ring. The Pair of Bayonet Adapter Rings differ from the Two-in-One Ring mainly in that, they can be separated.

In order to increase extension additional Tubes must be screwed between the adapters. These Extension Tubes are supplied in 3 lengths: 5 mm., 15 mm., and 30 mm. They are sold in complete sets together with the Pair of Bayonet Adapter Rings. The Two-in-One Ring is, of course, supplied singly.

Clamping Ring of the Back Bayonet Ring

The Back Bayonet ring has a Locking ring serving the following purpose: When using the Pair of Bayonet Adapter Rings and Extension Tubes the lens is often turned on its axis so that the lens-scales are difficult to read. This can be avoided as follows: First turn the notch of the rear bayonet ring to the left (looking on face of camera), then you can turn the other extension increases with the lens into the position desired (e.g. when using the Autocouple Extension Release, the release buttons of camera and lens must lies exactly on behind the other). By turning the notch for handling to the right the lens and the other extension increases firmly screwed together are fixed in this position. If the front extensions (front bayonet ring or tubes) shall be removed from the rear bayonet ring, turn the notch for handling also to the right, then the extension increases can be screwed out. When inserting and removing all extensions with rear bayonet ring, always seize the notch for handling.

Ihagee Autocouple Extension Release

In normal practice employing lenses with A.P.D. pre-setting device first the diaphragm, and then the camera shutter are released. In normal practice the button of the Automatic Pre-set Diaphragm lenses which is situated immediately in front of the camera body release is first depressed, followed by the actual firing of the shutter by the camera body release. When employing Bayonet Adapter Rings and Extension Tubes, however, the Ihagee Autocouple Extension Release has been produced specifically in order that the automatic lens mechanism may still be used. It consists of the following single parts:

  1. the coupling rod
  2. the release part
  3. the pressure part and
  4. the push button

According to the length of the additional extension release part b) and pressure part c) are adjustable and interchangeable on the coupling rod a).

In actual practice there are, basically, two possibilities as follows:

  • For short extension up to 15 mm. (Two-in-One ring, Pair of Bayonet Rings with, or without a 5 mm. Extension Tube). In this instance, pressure part c) with push button d) are screwed into the release button of the lens whilst the pointed contact of release part b) is inserted into the release button on the EXAKTA Varex. The distance between the release button and pointed contact having been adjusted according to the length of the actual extension, by tightening the knurled locking screws. In this way the coupling between the two release buttons is restored, and by single pressure of the finger on release button d) both the lens diaphragm and the camera shutter are release simultaneously.
  • For extension from 20 mm. to 60 mm. (pair of Bayonet Adapter Rings and Extension Tubes) parts b) and c) must be reversed. In this case, therefore, the pointed contact of part b) is inserted into the lens release and the pressure part c) is screwed to the camera release by means of release button d). Then as previously stated the knurled screws are tightened and the camera is then ready for releasing again. Automatic single pressure coupling is thus achieved as described above
  • In order to guarantee perfect functioning, please, note the following when connecting the Autocouple Release to the camera:
    • When the pointed contact of the release part has been inserted into the release button, the pressure part has to be close to the release button (always mount the Autocouple Extension Release to the camera with diaphragm wound up)
    • Besides, the coupling rod should always be parallel to the optical axis. This is easily achieved by turning the lens so that both release buttons lie in the same direction, also when using additional extensions. For this purpose the rear bayonet ring (next to the camera) is fitted with a locking device.

Important Note

Close-up and micro exposures with the EXAKTA Varex are not only obtainable with the accessories described in this booklet. For achieving utmost economy in this field, as well as in other spheres of photography, the "Vielzweck"-Multi-Combination for the EXAKTA Varex has been designed. Here just a short reference to the individual groups of the "Vielzweck": For close-up and magnifier work there is the Bellows Attachment. Reproductions are conveniently carried out with the help of the Copying Stand, which, by the way, also serves as a sturdy table tripod for other purposes. The Bellows Attachment and Copying Stand combined are used for photomicrography. Duplicates of small transparencies, on an optical basis, are made with the Transparency Copy Equipment. For medical photography, especially for photographing cavities of the body, the "Kolpofot" has been especially constructed. It works in connection with and electronic flash unit.
