Fully Multi Coating: Fully Multi Coating is applied to transmission surfaces of all lenses. It brings better clarity and color restoration.

　Bak4 Material: BAK4 has higher light reflection than BK7. It can effectively shorten the optical path and make the structure of optical products more compact.

　Nitrogen Filled: Due to the lower preparation requirements for nitrogen compared to argon, it is cheaper.

　High Definition: HD (High Definition) optical system makes images cleaner and sharper.

　IPX7: Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed in water under standardized conditions of pressure and time.
