    5. Infinity Compensation Mark Infinity compensation mark Distance index To compensate for shifting of the infinity focus point that results from changes in temperature. The infinity position at normal temperature is the point at which the vertical line of the L mark is aligned with the distance indicator on the distance scale.
  • Page 8 7. Picture Taking Normal Photography The lens can be used as a telephoto lens for normal photography. Closeup Photography Close-up photos (minimum focusing distance of 0.48m) up to 1x (life-size) magnification are possible. The minimum focusing distance is the distance from the subject to the film plane. The distance from the front of the lens to the subject (working distance) is about 0.25m.
  • Page 9 8. About Exposure Setting the Exposure When taking photographs using TTL metering, no exposure compensation is necessary to meter the light coming through the lens. With TTL metering, AE (autoexposure) is possible at all focusing distances. Just set the desired picture-taking mode, then check the shutter speed and aperture before taking the picture.
