Lens Setup and Focus Procedures

VIDEO DRIVE AUTO IRIS LENS

Set the lens mode selector switch to AIV. Switch the ESC and AGC OFF. Refer to the lens instructions and adjust the lens for the optimum picture (video output level of 1 Vp-p). To focus, completely open the iris by covering the lens with a suitable neutral density (ND*) filter. If the viewed scene is 6.5 ft (2 m) away or farther, set the lens focus to infinity (far). Use the back focus adjustment ring (refer to Back Focus Adjustment on page 14) and focus on the selected scene. Remove the ND filter and set the lens focus as required. Set the AGC switch to ON, as required. Most scenes benefit from AGC.

DIRECT DRIVE DC AUTO IRIS LENS

Set the lens mode selector switch to AID (default setting). Set the ESC and AGC switches to OFF. Use an appropriate screwdriver to completely turn the lens level potentiometer (refer to Figure 1) clockwise. Next, slowly adjust the potentiometer counterclockwise until the optimum picture is obtained (video output level of 1 Vp-p). To focus, completely open the iris by covering the lens with a suitable neutral density (ND*) filter. Select the scene to be viewed. If the viewed scene is 6.5 ft (2 m) away or more, set the lens focus to infinity (far). Use the back focus adjustment ring (refer to Back Focus Adjustment on page 14) and focus on the selected scene. Remove the ND filter and set the lens focus as required. When finished, set the ESC and AGC switches to ON.

FIXED LENS, NO IRIS

Set the ESC and AGC switches to ON (default settings). To focus, set the lens focus to infinity and view an image more than 6.5 ft (2 m) away. Focus the image with the back focus adjustment ring (refer to Back Focus Adjustment on page 14). Set the lens focus as required.

MANUAL IRIS LENS

Set the ESC and AGC switches to ON (default settings). To focus, open the iris fully and set the lens focus to infinity. View an image more than 6.5 ft (2 m) away. Focus the image with the back focus adjustment ring (refer to Back Focus Adjustment on page 14). Adjust the lens focus and set the iris (if equipped) for the best picture quality. The largest aperture gives the best light sensitivity; the smaller the aperture, the greater the depth of field.

ZOOM LENS

Set the lens focus to infinity (far) and completely open the iris by covering the lens with a suitable neutral density (ND*) filter. Zoom out to the widest field of vision and view a distant object. Adjust the back focus adjustment ring until the object is in focus (refer to Back Focus Adjustment on page 14). Next, zoom completely in and adjust the lens focus until the object is again focused. Repeat these steps until the full zoom range may be viewed with the minimum loss of focus.

*NOTE: For best results outdoors, use an ND3 filter.
