User manual HARTBLEI MC TS-PC 3.5-45 SUPER-ROTATOR

[. . . ] The lenses TS-PC (Tilt-Shift) and TS-PC (Tilt-Shift) Super-Rotator are manufactured with Pentacon Six (identical to Exakta 66, Kiev 60), Mamiya 645, Contax 645 and Pentax 645 bayonet. There is also the option of mounting the lens via an adapter on a 35mm camera. In this way, the parameters of shift are increased. S P EC IFIC A T N S IO Bayonet type: PCS . . . [. . . ] Due to the design characteristics of the TS-PC and TS-PC Super-Rotator lenses with the Pentacon Six bayonet type, it is desirable to use the shift adjustment after the tilt value has been fixed. In the TS-PC lens with the Pentacon Six bayonet while the maximum tilt is set, the shift against the tilt direction shall not exceed 10 mm. In the TS-PC Super-Rotator lens with the Pentacon Six bayonet while the maximum tilt is set, the shift against the tilt direction shall not exceed 9 mm. In order to prevent inaccurate operation, it is recommended that after each shot, return the parameters of the shift and tilt to the initial (zero) position. Finding the Exposure when Using Lens Shift When shifting the lens, it is necessary to introduce exposure adjustment of the external or handheld (not TTL system) exposure meter. 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 makes +0. 25 of the aperture step, at the shift of 12 mm - makes +0. 5. Tilting the TS-PC and TS-PC Super-Rotator Lenses Lens tilt is achieved by rotating clockwise the tilt handle. One full revolution of the handle corresponds to a lens tilt of 1. 13° for the TS-PC lens and 1. 5° for the TS-PC Super-Rotator lens. The direction of the tilt for the TS-PC Super-Rotator lens is made by rotating the lens about the bayonet axis. To rotate the lens, depress the tilt direction release button on the tilt mechanism in the direction of the pointer. The lens can be turned around the bayonet axis 360° in any direction and fixed every 15°. The lens may operate in the position between these intervals as well. MC TS-PC HARTBLEI 3. 5/45 MC TS-PC HARTBLEI 3. 5/45 Super-Rotator If applying the tilt when photographing, obey the Scheimpflug's principal, which states that if a lens is tilted such that the lens plane intersects the film plane, the plane of sharp focus must also pass through that same line of intersection. Remember that when using the TS-PC or TS-PC Super-Rotator lens with Pentacon Six bayonet type it is recommended to set up the tilt angle with the zero position of the shift. Finding the Exposure when Using Tilt of the TS-PC and TS-PC Super-Rotator Lenses With the lens tilt and the aperture open, there will be a difference in quantity of light entering the opposite edges of the frame. To correct it, choose the exposition pair " exposure-aperture" with the aperture closed down to 5. 6 - 22. 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). [. . . ] When dust appears on the surface of the lens, blow it off with a " rubber pear". When fingerprints and other spots appear on the surface of the lens, first remove the dust from the lens and casing around. Then, using a special rice paper, natural cambric or new non-colored suede (a special suede for cleaning optics), wipe the lens with circular motions (from center of a lens in a spiral to edges) applying no pressure.
