Rainbow EX-TUBE CCTV Lens Extension Kit For Close Up Viewing
The EX-TUBE lens extension kit accessory allows you to reduce the minimum object distance of any cctv lens, therefore allowing you to achieve good focus on any object up close. These 5 metal spacers can be used alone or in combination for the desired results. The 5mm spacer is the same as the CS/C adapter used to convert any C mount lens use on CS mount surveillance cameras.
Notes: Camera lens will not focus normally with this kit, used for close-up viewing only. When using with a zoom lens, you will lose tracking (picture staying in focus) when zooming in and out. The CCTV lens will only focus at one distance.
