Operating Instructions

11
The detachable folding focusing hood includes a depth-of-field table for evalu-
ating the depth-of-field for lenses of 90 to 300 mm.
Based on the distance selected a certain depth-of-field value can be determi-
ned for the necessary aperture. The data found are only valid for a camera
either totally unadjusted (basic position) or adjusted parallel.
When operating with adjustments according to Scheimpflug the aperture
selected may be considerably higher (lower f-stop figure).
9. DISTANCE SCALES
(classic and 2000)
Distance scales assist the focusing control of unadjusted cameras. The index
has to be located on the infinity mark at the distance scale corresponding to
the lens used.
The distance scale stage carries up to 3 scales. One each for wide angle,
normal and telephoto lens. Their color corresponds with the color of the infi-
nity stops and range finder coupling cams. For telephoto and long focus len-
ses the distance scale located near the front edge of the drop-bed applies.
When more than three lenses are used on the camera, the scale stage may be
exchanged for another one simply by pulling it off its dovetail.
