Focusing To focus, rotate the focusing ring with the distance scale on it until the image is sharp in the viewfinder (it is preferable to do this with the aperture being maximum open). The distance scale can be used instead to give an approximate focus. Determine the depth of field using the distance scale and the depth-of-field scale, and check it visually by the image on the focusing screen, in the viewfinder at the chosen aperture. When focusing the lens after it has been shifted, it is possible that the microprism and the split-image rangefinder of the viewfinder of the camera may darken. In that case, check the image sharpness on the matte spot of the focusing screen. Orientation based on a distance scale after the lens has been shifted shall not give precise result. MC PCS HARTBLEI 3. 5/45 Aperture Setting MC TS-PC HARTBLEI 3. 5/45 MC TS-PC HARTBLEI 3. 5/45 Super-Rotator To set the aperture, rotate the aperture ring with the scale number on it until the selected one matches with the red mark on the fixed ring. Lens Shifting To shift the optical unit of the lens, rotate the shifting ring with the shift scale on it. Choose the direction of the shift by rotating the lens about the bayonet axis. To rotate the lens, push the shift direction release button on the shift mechanism. Finding the Exposure when Using Tilt-and-Shift of the TS-PC and TS-PC Super-Rotator Lenses When tilting and shifting the lens simultaneously it is necessary to introduce exposure adjustment to the external or handheld exposure meter (not TTL system). The exposure adjustment increases from 0 to +0. 5 of the aperture step that is proportional to the shift of the lenses optical system. So, at the shift of 6 mm, adjustment is +0. 25 of the aperture step, at the shift of 12 mm - is +0. 5. When using lens tilt and open aperture there will be a difference in the quantity of light falling on the opposite edges of the frame. The simultaneous shift of the optical unit magnifies the effect. It is recommended to work with a film with large exposure latitude. With 6° tilt (and more for TS-PC Super-Rotator) and simultaneous 6 mm and more shift for 6x6 format vignetting occurs. With 6° tilt (and more for TS-PC Super-Rotator) and simultaneous 9 mm and more shift vignetting occurs in both 6x6 and 6x4. 5 formats. P R A C T A LA D V IC ES A N D EXA M P L IC ES Bellow you find several pairs of pictures that illustrate possibilities provided by the lens shift and/or tilt functions. The picture « A» illustrates the standard position in which lens shift and/or tilt functions are not used, and the picture " B" illustrates the uses of the given functions. Both shots from each pair are made without change of the point of shooting. Remove or Increase the Distortions With the help of the control system of PCS and TS-PC lenses, you can if necessary remove or increase the effect of difference of level between a photographer and an object (Photo 1A, 1B). Photo 1A Photo 1B When photographing architectural objects, the distance from the lens to upper and lower parts of the object is different. [. . . ] It would allow you to work without polarization filters and labor-consuming retouching of the photograph on your computer (Photo 3A, 3B). Photo 3A Photo 3B Tilting the TS-PC and TS-PC Super-Rotator Lenses and Adjusting Depth of Field While photographing interiors, still lives, portraits, objects for advertising it often happens that total control of the depth of field is required. With ordinary lenses, it is achieved via the aperture. The most widespread method to increase the depth of field is to minimize the aperture of the lens. However, it frequently happens that this is not possible: when you close the aperture, it is necessary to increase the exposure. [. . . ]
