User manual NIKON AI-S ZOOM-NIKKOR 35-70MM F/3.5

[. . . ] The lens couples fully to both the full-aperture metering systems and automatic diaphragm mechanisms of all Nikon and Nikkormat cameras. MOUNTING A Align the aperture index of the lens with the mounting index of the camera; then position the lens in the camera's bayonet mount. Twist the lens counterclockwise until it clicks into place. [. . . ] (For details , also refer to your focusing screen's instruction sheet). €¢ When the Teleconverter TC-201 or TC-200 is attached to this lens, use the following table: ~ Camera _ F3 F2 Screen '——~___ A/L a c D E Gl 3 G2 63 S4 HI H2 H3 H4 J K P MR T U • • a o 3 • • • • • •o • 10 •When the Teleconverter TC-14A is attached to this lens, use the following table; G3 G4 HI H2 © = Excellent focusing • = Acceptable focusing The split-image rangefinder, microprism or cross-hair area is dim. O = Acceptable focusing Slight vignetting (or moire phenomenon, in the case of the microprism) affects the screen image. The image on the film, however, shows no trace of this. El = Exposure measurement not possible; lens/screen combination permits only focusing operation. ZOOMING D By rotating the zoom control ring, the focal length of the lens can be varied continuously between 35 and 70mm. This enables you to "trim" the composition to fit the film frame exactly. Once set, the focus does not change regardless of the focal length used. However, it is recommended that you focus on the maximum zoom setting (70mm) and zoom back to the preferred composition; since depth of field is shallowest at longer focal lengths, focusing is made easier. This technique will assure you of obtaining the maximum image quality that the ZoomNikkor 35-70mm f/3. DEPTH-OFFIELD SCALE Unlike other Nikkor lenses, the Zoom-Nikkor 35-70mm f/3. 5 has no color-coded depth-of-field indicators engraved on the lens barrel. However, you can still determine the depth of field by using the scales on page 25. To use, first cut out the scales along the lines indicated. Then, place the subjectdistance scale (B) over the depth-of-field scale (A) with the top edge of the B scale lined up with the focal length in use and the focused distance aligned with the A scale's central indicator line. Now read off the numbers (on the B scale) which appear opposite the pair of depth-of-field lines (on the A scale) corresponding to the aperture in use; these numbers express the depth of field for the settings in use. [. . . ] If this happens, wipe it again with a cotton cloth moistened with alcohol. €¢ To protect the lens surface from dirt or damage, the use of an L37C or L1BC filter is recommended at all times. The lens hood also helps to protect the lens. [. . . ]
