Appendix C - Lenses and Advanced Focusing
Your camera was supplied either without a lens (AXIS 2420), or with a DC-Iris lens (AXIS
2420 W/Lens). Either model can be fitted with any standard CS/C lens. The DC-Iris support
included with the AXIS 2420 will drive any standard DC-Iris lens.
Fitting a Lens
Note: The AXIS 2420 is equipped with a CS-mount, so any standard CS lens can be fitted directly. To
mount a C-type lens, a CS-C adapter must also be used. The adapter effectively moves the lens
5mm away from the camera’s CCD.
Follow the instructions below to fit any C or CS type lens:
1. C-lens only: Attach the new lens to a CS-C Adapter.
2. Screw the lens onto the AXIS 2420. If applicable, adjust the iris according to the
prevailing light conditions.
3. Referring to Focusing Procedure, on page 56, adjust the camera focus.
4. Adjust the DC-Iris settings. See page 57.
5. Refresh your browser and check the results from the camera’s Home Page.
Caution!
Exposing your camera to bright sunlight may cause permanent damage to the CCD if you:
• use a non-DC Iris lens, or
• select anything other than DC-Iris in the Exposure Control settings of the Image - Advanced page.
Axis consequently advises extreme caution when fitting a lens to your AXIS 2420 and/or when using the
Image - Advanced settings. Damage caused to the AXIS 2420 through overexposure to direct sunlight or
halogen light is not covered under the product warranty.
