Pentax K100D Service Manual page 88

• Performance capabilities such as auto-focus speed, shutter lag time and continuous
shooting rate are unaffected by the SR system because its operation is instantaneous,
occurring within the normal exposure interval.
• By building the Shake Reduction system into the body, the PENTAX SR system provides
maximum flexibility and requires no compromises in optical quality.
• To provide optimal Shake Reduction, the camera must "know" the focal length of the
lens in use. PENTAX F, FA, D-FA, and DA series lenses automatically relay focal length
information to the camera. With older lenses, the PENTAX K100D allows users to
manually input focal length information via the Shake Reduction menu which allows
focal lengths all the way from 8mm to 800mm
