Large-scale views of small objects and animals, or full-frame copies of pictures and documents are particularly fascinating and interesting subjects - and often important for professional purposes. The Voigtlander Proximeter for the Prominent and Vitessa makes the job really simple.

The special advantage of this ideal close-up attachment is that it permits hand-held near shots with the camera instantly ready for action - an important point with live or other rapidly moving subjects. At the same time the viewfinder parallax error is automatically corrected, and even at closest range the eye views the image as at infinity.

These features of the Proximeter system are based on two firmly connected supplementary lenses. One is a positive meniscus element for the camera lens and the other a spheric/prismatic unit to deflect the rays going through the two rangefinder windows. As a result the camera lens is coupled to the rangefinder just as accurately at close range as over the normal focusing range from infinity to three and a half feet.

Instructions For Use

The Proximeter close-up attachment is available in two focal lengths covering the following focusing ranges:

Proximeter I (focal length 38 inches or 95 cm.): 38 to 18 inches (95 to 47.5 cm.)

Proximeter II (focal length 20 inches or 50 cm.): 18 to 13 inches (49 to 32.5 cm.)

Combining the Proximeter I and II produces a focal length of 13 inches (33 cm.) covering a focusing range from 13 to 9.5 inches (33 to 24 cm.)

Mounting the Attachment. Slack off the milled screw at the side of the Proximeter, push the clamping ring over the lens mount, and tighten the screw. Make sure that the metal frame of the Proximeter is parallel to the top edge of the camera. When using two units together, always mount the Proximeter II on the camera lens and the Proximeter I on the front mount of the Proximeter II; never the other way round!

Field Mask. For shots with the 4 inch (10 cm.) Dynaron f/4.5 telephoto for the Prominent resp. Dynaret f/4.8 for the Vitessa T a special field mask is available which is fixed between the camera lens and the Proximeter (see main pictures).

Aperture and Depth of Field. To ensure adequate depth of field in the picture, it is advisable to stop down at at least f/5.6 ot f/8, or when copying documents even to f/8 or f/11. The tables on the following pages give the available depth of field at various apertures and distance settings. See Tables for Depth of Field Tables (captured as images).

Exposure. The use of the Proximeter does not call for any exposure compensation. When working with filters the appropriate filter factor must of course be taken into account. The filter is mounted on the outer mount of the Proximeter.

Taking the Picture. Sight the subject and focus the image within the distance range of the Proximeter used by means of the camera rangefinder. The rectangular finder frame shows the exact field of view for the 2 inch (5 cm.) lens. When taking pictures with the 4 inch (10 cm.) telephoto lens Dynaron f/4.5 resp. Dynaret f/4.8 the red frame indicates the correct field of view at a setting of 3' 6" (1 m.), whilst the yellow frame on the field mask indicates the field of view with the lens set to infinity.
