Other lenses in the same price range are partly plastic. Surface finish: Our lenses are treated with oxidation, which is standard for the optical instrument. However, others use " painting" instead of "sand oxidation". The surface turns out with low hardness, thus fragile and easy to scratch. The result is a much shorter life. Processing technology and design standard: Our lenses are designed following Korean and Japanese standards. Our manufacturer uses CNC( Computerized Numerical Controlled) lathe and milling machines, therefore, our housing parts are high-precision, smooth, and highly finished. However, others use outdated ordinary lathe and milling machines. The lenses have big gaps so that they use a lot of "damping grease" to seal the gap. The main problem is grease will melt in summer and blur the lenses, which is very hard to clean. Only a special chemical fluid can wash the grease off. Assembling: All of our lenses are assembled in a Clean Room, which delivers a higher quality lens.
