Kenko Square Conversion Frame, 100mm-width filter holder for φ82mm screw-in filter

"Kenko Square Conversion Frame for Φ82mm" is a conversion adapter for mounting screw-in Φ82mm lens filters on a square holder.
It is compatible with square filter holders for 100mm-width, 2mm-thick square filters.

Quickly attach, detach, and adjust the position by sliding the frame as if using a rectangular filter. It can also be used in conjunction with square filters.

The Kenko Night Focus filter (sold separately) is a useful tool for focusing on stars when shooting star scenes, but the filter must be removed when shooting. The Square Conversion Frame minimizes the time and effort required to attach and remove the filter, allowing you to take beautiful star-focused photographs.
