K&F Concept X-PRO square filter holder with built-in 95 mm CPL filter and 4 adapter rings

X-PRO square filter holder with built-in 95 mm CPL filter and 4 adapter rings. It suits landscape photographers who shoot long exposures on a wide-angle lens and want a polariser and square filters in one holder without dark corners.

• 12 mm frame, 91 mm clear aperture
• Built-in 95 mm CPL, 36 coatings
• Adapter rings 67, 72, 77 and 82 mm

A slim frame without dark corners

The X-PRO holder carries two square filters plus a built-in 95 mm circular polariser at the back. The frame is only 12 mm thick with a 91 mm clear aperture, so no dark corners appear even on a wide-angle lens.

Adapter rings from 67 to 82 mm

The holder mounts on a 67, 72, 77 or 82 mm adapter ring screwed into the lens thread. The square filters come out without removing the holder, and no side light leaks in between the filters and the lens.

The polariser is AGC optical glass with 36 coatings, polished on both sides; it repels water and grease and resists scratches. It is turned with a wheel on the holder, so the effect can be fine-tuned even with the square filters in place.
