Selling to declutter. Purchased in October 2020 from Amazon. To be honest, I haven't used it much since I bought it. To avoid any misunderstandings, I've marked the overall condition as poor. Available for immediate purchase. 【Product Information (from Amazon)】 ● Square Filters Medium GND8 100x150mm Reverse GND8 100x150mm ND64 100x100mm ND1000 100x100mm ● Filter Holder: Holds 3 square filters (100x100mm or 100x150mm) and 1 dedicated circular filter. The new design with cut corners makes it easier to insert and remove filters. Also, the newly designed clip allows for smoother filter sliding, and the locking screw allows for rotation to be fixed. ● Main Adapter: Adapter compatible with 82mm filter diameter. Equipped with a rotating knob that allows you to adjust the angle of the CPL filter while the square holder is attached. Compared to the V5 PRO, the thread part of the main adapter is made higher, making it easier to attach and detach the CPL filter. ● CPL Filter: This kit includes the "Landscape CPL". ● Adapter Rings: Used when changing the diameter of the main adapter. Includes 67mm, 72mm, and 77mm rings. ● 100mm System Square Filter Case Plus: The 100mm System Square Filter Case Plus can store up to 9 square filters (100 x 100mm or 100 x 150mm), protecting the filters in separate storage pockets. ● V6 Lens Cap: Covers the CPL filter when the filter holder is removed.
