      differing lens mounts.  lf you are now using two
      different SLRs or if you someday replace your
     present camera with a camera of different make,
     you can still use your entire range of Vivitar
     T-4 Lenses by simply changing the automatic
     T-4 Adapter. These Vivitar T-4 Adapters are
      available for most 35mm SLR camera mounts
    and feature automatic diaphragm mechanisms
    and full meter coupling to behind-the-lens
     exposure controls of the camera.
     Attached without the need for any tools,
     bands, rings or special couplings, the unique
     breech-lock design of a Vivitar T-4 Adapter
    when mounted on a T-4 Lens results in a
     combination that has the integrity of your
     camera's normal lens. Accidental separation or
     loosening through wear is virtually impossible.

     This scale shows you the range of subjects which will appear in sharp focus on
     the film. This range will vary with the aperture selected, and is indicated by
     the reference marks bordering the distance index mark. The smaller the
     aperture (numer.ically higher), the deeper the depth-of-field, and vice versa.
    INFRARED INDEX MARKS
    The red marking on the right half of the depth of field scale is a focusing
      reference when using infrared film. Focus normally first, read the distance as
      indicated opposite the distance index mark, then turn the lens barrel until the
     distance reading is opposite the Infrared Index Mark. The lens is now focused
      for infrared photography.
    DISTANCE SCALE
     This scale, in both feet and meters, gives the distance between the subject
      in focus and the film surface in your camera.
