How Do You Prevent Fungus On Lenses?.
Fungus on Lenses: A Guide to Prevention and Removal
As avid photographers, we cherish our cameras and lenses, investing significant time and resources in capturing the world's beauty through the lens. However, these delicate instruments are not immune to the perils of the environment, with fungus being a potential threat that can cause irreparable damage.
What Is Lens Fungus?
Lens fungus, also known as mold, is a type of microscopic organism that thrives in dark, moist environments. It can grow on various components of the lens, including the front element, rear element, and internal lens elements. Once established, fungus can spread rapidly, distorting images and reducing the sharpness and clarity of your photographs.
Causes of Lens Fungus
Lens fungus is typically caused by prolonged exposure to moisture and insufficient ventilation. Humidity levels above 65% and sudden temperature changes can create an ideal environment for fungus growth. Additionally, storing lenses in dark, enclosed spaces like camera bags or cabinets can exacerbate the problem.
Preventing Lens Fungus
While there's no foolproof way to guarantee complete protection, several proactive measures can significantly reduce the risk of lens fungus. Here's a comprehensive guide to preventing lens fungus:
-
Regular Cleaning: After each use, wipe your lenses with a microfiber cloth to remove any moisture, dust, or fingerprints. Avoid using harsh chemicals or lens cleaning fluids that can damage the lens coating.
-
Proper Storage: Store your lenses in a cool, dry place with a constant temperature. A humidity-controlled cabinet or a closet with good ventilation are ideal options. Consider investing in silica gel packets to absorb excess moisture.
-
Avoid Extreme Environments: Avoid exposing your lenses to extreme temperatures or humidity levels. This includes storing lenses in hot cars or in direct sunlight for extended periods.
-
Protect from Liquids: Keep your lenses away from water, rain, or other liquids that can cause condensation and encourage fungus growth.
-
Regular Inspection: Periodically inspect your lenses for any signs of fungus, such as discolored spots, smears, or haze. Early detection is crucial for prompt removal.
Remedies for Existing Fungus
If you suspect your lens has fungus, it's essential to address the issue promptly to prevent further damage. Here's a step-by-step guide to cleaning and restoring your lens:
-
Disassemble the Lens: If possible, disassemble the lens to thoroughly clean all internal elements. Take care not to damage or lose any screws or delicate parts.
-
Spray with Isopropyl Alcohol: Use a spray bottle containing 99% isopropyl alcohol to carefully clean the lens components. Avoid direct contact with electronic components or rubber seals.
-
Rinse with Distilled Water: Rinse the lens components with distilled water to remove any isopropyl alcohol residue.
-
Dry Thoroughly: Allow the lens components to air dry completely in a dust-free environment. Avoid using heat or direct sunlight to dry the lens, as this can cause further damage.
-
Reassemble and Test: Once the lens is completely dry, reassemble it carefully and test its performance. If any residual fungus remains, repeat the cleaning process.
Seek Professional Assistance
If you're unsure about the severity of the fungus infestation or lack confidence in your DIY cleaning skills, it's advisable to seek professional assistance from a reputable camera repair shop. They have the expertise and specialized equipment to safely and effectively remove lens fungus without causing further damage.
Preserving Your Lens Investments
By following these preventative measures and acting promptly if fungus is detected, you can significantly reduce the risk of lens fungus and safeguard your valuable investment in capturing remarkable images. Remember, prevention is always better than cure, so take care of your lenses to ensure they continue to deliver stunning photographs for years to come.
