Normal camera using lubricant which will be volatilize in hot environment , that will make lens out of focus and picture blurring .So we spent a lot of time on searching solution for this issue.After a dozen times tests, we find a successful solution-- spring lens.

SPRING LENS FEATURES:
First, the lens is made by die-casting mould,without any lubricant.Second, we use the tension of the spring,avoiding the focus error affected by the high temperature or shake. Third, luminous flux of spring lens is F/1.4 which is much better than normal F/1.2 lens.
