Description
These lenses are varifocal lenses designed for 1/3-inch format cameras with 5 megapixels (MPx) or less in resolution. These lenses, which were designed
for CS-mount cameras, produce high precision images from the image center to the image corner, fully exploiting the performance of megapixel cameras.
Megapixel lenses are best suited for high-quality image surveillance with a megapixel camera as well as with a standard definition camera.
MODELS
Installation
1. Press the threaded portion of the lens mount against the threaded portion of the camera mount.
2. Slowly rotate the lens clockwise.
3. Screw in the lens mount.
4. Connect the auto iris lens cable to the electrical connector on the camera.
NOTES:
• The lens mount is equipped with a slip mechanism. To change the rotational position of the lens, rotate the lens until it reaches the stop (cannot be
rotated further), and then rotate it counterclockwise to the required position.
• The iris control for this lens cannot be activated with a video signal. Use a camera that can send a DC signal.

Operation
ADJUSTING THE ZOOM
NOTE: The lens is a varifocal lens. After a zoom operation, you will need to set the focus.
1. Loosen the zoom tightening knob.
2. Rotate the zoom ring to select the appropriate angular field of view.
• Rotate the ring to “W” to set the zoom to wide.
• Rotate the ring to “T” to set the zoom to telephoto.
3. Adjust the focus; refer to Setting the Focus.
4. Tighten the zoom tightening knob.
SETTING THE FOCUS
1. Loosen the focus tightening knob.
2. Rotate the focus ring to adjust the focus.
• Rotate the ring to “F” to set the focus to infinity.
• Rotate the ring to “N” to set the focus to near.
3. Tighten the focus tightening knob.
SETTING THE AUTO BACK FOCUS
Megapixel lenses work with Pelco’s Sarix® cameras. The auto back focus feature of Sarix cameras saves time because a single button sets the auto back
focus mechanism.
To Set the auto back focus:
1. Press the button once to center the auto back focus mechanism and to fully open the iris.
2. Press and hold the button for three seconds to start the auto back focus mechanism.
NOTE: If you do not have a camera with auto back focus and you cannot get the lens to focus despite repeated attempts, refer to Adjusting the Camera
Flange Focal Length and the appropriate camera manual for detailed instructions.
ADJUSTING THE CAMERA FLANGE FOCAL LENGTH
1. Open the lens iris.
2. Set the zoom at the wide end and the focus at the near end for 13M2.2-6, 13M2.8-8, and 13M2.8-12. For the 13M15-50 lens, set the zoom at the
telephoto end and the focus at the infinity end.
3. Operate the flange focal length adjustment mechanism on the camera, and then focus on an object at 11.8 inches (0.3 m) from the lens for the
13M2.2-6, 13M2.8-8 and 13M2.8-12 lenses. For the 13M15-50 lens, focus on an object that is more than 8.8 yards (8.0 m) from the lens.
4. Confirm the focus at the telephoto end, around the middle, and at the wide end throughout the zoom range.
5. If necessary, repeat this procedure until the focus is correct.

ROUTINE SERVICING
A special coating has been applied to the lens surface to prevent light reflection. A dirty lens surface due to dust, oil, or fingerprints causes harmful glare,
which degrades the lens properties. Dirt can also cause mold or scratches on the lens.
NOTE: Be careful not to damage the lens while cleaning.
To remove dust, brush or dust off the lens with an oil-free soft brush or blower brush (for photography use).
To remove oil, fingerprints, or water drops:
1. Apply alcohol or lens cleaning liquid to a clean, soft, oil-free cotton cloth or lens cleaning paper. Using a spiral motion, moving from the center of the
lens to the rim, gently wipe the lens.
2. With another clean soft cloth, gently wipe off the rest of the dirt, and then dry the lens surface.
3. Repeat this process as necessary until the lens is completely clean.
Specifications
NOTE: When power is turned off, the iris will close automatically.
