ZOOM LENSES (PARFOCAL LENSES ONLY)
1. Zoom the lens into maximum zoom.
2. Adjust for best focus on an object within the normal focus range, perhaps a few
meters away.
3. Zoom the lens all the way out.
4. Loosen the Back-Focus lock screw on the bottom of the camera by about 1 turn
using the included 2mm Allen key.
5. Rotate the entire lens allowing the CS ring to screw in or out. Adjust the rotation
until best focus is obtained on the same object.
• Do not adjust the focus ring on the lens.
• If the CS ring will not rotate far enough, check to see if your lens requires
a CS-C adapter. Please refer to Pg. 43 for additional details.
6. Tighten the Back-Focus lock screw, finger-tight.
7. Repeat steps 1 to 6 until the lens is in focus when zoomed in and when zoomed
out, without adjusting the focus control while zooming.
