Description

Square filter holder for 75mm width The holder is precision and robust and strong enough to hold the filter and is designed to prevent the filter from accidentally moving or falling out. The holder and lens are also smooth to put on and take off, and the overall feature is comfortable to operate.
When shipped, the filter mount is screwed onto the outside of the holder to insert up to three square filters. If you replace the included screws (shorter than standard), you can use up to 2 pieces to reduce vignetting when using ultra-wide angle lenses.
