Some B60 lenses have plastic front barrels, which are extremely easy to damage.
For example, CFE80
Unlike ordinary lenses, this lens has a more complex structure and is more difficult to process. There has been no solution for a long time, but we have finally overcome the difficulties.
Integrated CNC cutting, the inner bayonet has been changed to a 67mm universal UV lens thread, allowing users to use their preferred UV lens without worrying about it falling off.
Upgraded to 7075 aerospace aluminum and then hardened. The surface was also finely polished and hand-ground.
The appearance and feel are identical to stainless steel, with excellent luster, while also being acid and corrosion resistant and lightweight.
I hope everyone has a good time.
Installation method: Unscrew the original front nameplate. A special tool is provided for non-destructive removal. Molded to the original size for non-destructive installation and replacement. If you are unsure how to install, please consult customer service.
