Product Precautions for Normal Use
- Please avoid any long-term exposure to the lens in a wet environment which may produce mold and rust on the lens. Store the lens in an airtight cabinet with a drying agent. For other options, contact your SIRUI rep for information on a SIRUI High Performance Humidity Control Cabinet or visit www.sirui.com.
- Do not touch the lens glass surface with your fingers. Gently remove dust and dirt with a cleaning cloth or lens brush. Wipe off fingerprints with lens cleaning products and a lens cloth. Do not clean the lens with general household cleaners.
- Please avoid using the lens in the rain or near water as this may damage the lens and void the warranty.
- When transporting the lens from a hot and cold environment, please place the lens into a lens case or a commercial camera bag. When removed, allow the lens some time to adapt to the new temperature as the lens interior may develop condensation if not.
