K&F Concept 55 mm Magnetic Adapter Ring

The K&F Concept 55 mm magnetic adapter ring screws into the lens thread and holds K&F Concept magnetic filters, which you can then attach and remove in one movement. The frame of aviation-grade aluminium alloy is only 2.16 mm thin, so it does not cause vignetting even on wide-angle lenses. The ring works only with K&F Concept 55 mm magnetic filters.

Strong magnet for quick filter changes

The magnetic attachment holds the filter securely and a filter change takes just a moment. The ring stays screwed onto the lens and you simply place K&F Concept magnetic filters on it – no screwing and no risk of a jammed thread.

Slim aluminium alloy frame

The frame is made of high-strength, impact-resistant aviation-grade aluminium alloy. The black anodised finish prevents reflections while shooting, and the CNC-machined non-slip knurling makes screwing on and off easy. The frame is just 2.16 mm thick.

For the K&F Concept magnetic system only

The ring is designed exclusively for K&F Concept 55 mm magnetic filters. It cannot be used to adapt non-magnetic filters or non-magnetic adapter rings.
