B/ When using, please pay attention to the following points to prevent the lens from bursting and prolong the life of the lens.

a. The machine's air-cooled fault causes the lens to overheat and burst, or the air is not cold, and there is condensed water in the lens barrel to cause it to burst from hiding on the lens.

b. The back spray or liquid that occupies the carved material on the lens is prone to burst due to uneven heating for a long time. It is necessary to use a cotton swab to dip cleanly with anhydrous alcohol.

c. When dimming, the optical path hits the edge of the lens and the junction of the lens barrel, which can easily cause burst.
