Maintenance Guide for cine e mount lenses

The maintenance of cine e mount lenses should focus on cleanliness, moisture resistance, dust prevention, and temperature control. The specific methods are as follows:
Cleaning and dust prevention
External cleaning: Use an air blower (made of silicone material) to remove dust, and gently brush the bayonet and gear set with a soft bristled brush. ‌
Lens cleaning: Use only specialized lens cleaning solution (such as recommended by Zeiss or Canon), and gently wipe with ultra-fine fiber cloth or lens wiping paper to avoid direct contact of alcohol with the lens. ‌
Transportation and storage: Set the aperture to maximum and the focus to infinity, and store in a moisture-proof box or desiccant. ‌
Moisture and mold prevention
Humidity environment: Moisture proof boxes should be equipped in humid areas in the south, and timely cleaning should be carried out in windy weather in the north to avoid sand and dust entering the interior of the lens. ‌
High temperature environment: Avoid direct sunlight, cover the front and back covers when storing, and regularly check the lubricating oil status of the mirror assembly. ‌
temperature control
Low temperature environment: The working temperature range of the lens is -20 ℃ to 55 ℃. If it is below -20 ℃, the lubricating oil needs to be replaced to avoid condensation. ‌
High temperature environment: Avoid prolonged exposure to sunlight, regularly clean the casing and check the sealing. ‌
Physical Protection
UV filter/protective film: Installing a UV filter can reduce the risk of lens scratches, especially suitable for outdoor shooting. ‌
Light shield: prevents direct sunlight and accidental collisions, providing a cushioning effect. ‌
Special maintenance
If mold or mechanical failure is found, immediately stop using and contact professional maintenance personnel to avoid disassembling and causing secondary damage. ‌
