Attention
- To take the lenses from cold environment to warm environment, condensation might occur on lenses and internal parts. To prevent condensation under this circumstance, put the lenses inside an airtight plastic bag before taking them from cold environment to warm environment, After the lenses gradually become warm, take them out for use. Please follow this step too in taking lenses from warm environment to cold environment
- Please don’t put lens in places where temperature is too high such as cars directly exposed to the sun. High temperature might cause lens failures.
- To mount lenses on cameras, you’d better hold the lenses (do this too in mounting the lenses on the tripods).
Safety Instructions
- Please don’t view the sun or bright light sources through lenses or cameras, or else your eyesight will be impaired. It is especially harmful to directly watch the sun through lenses.
- Please don’t take photos by pointing the lenses or cameras at the sun. The lenses will focus on light, so the cameras will fail or be caught in fire even if the sun is not within the image area, or photos are taken against light.
- No matter if lens are mounted on the cameras, please don’t put the uncapped lenses in the sun, or else the lenses might converge light sources and thus cause fire.
Cleaning
- Please don’t directly touch lenses with hands, or else the lenses will become dirty. Please blow dust away with lens plunger, and gently scrub the lenses with clean soft lens-cleaning wipes.
- Please don’t use any organic solvent such as thinner and petrol to clean lenses.
