Xume 67mm (2.63") Filter Holder
The Xume 67mm (2.63") Filter Holder is a precision-machined metal ring that attaches to a 67mm circular screw-in filter to provide instant and secure attachment to lenses when a Xume Lens Adapter is installed. NdFeB rare Earth magnets are integrated within lens adapters to attach to the filter holder to and provide a strong, but easy to remove, connection that is suitable for use with oft-used filters. By using quick-to-remove magnets to attach filters, changing of filters can occur much more quickly and eliminates the chance of cross-threading or jamming when installing or removing filters.
The ring is approximately the same thickness as most step-rings and will not cause vignetting on most lenses with focal lengths as wide as 24mm (35mm equivalent). Over-the-lens type lens hoods are still compatible when Xume Adapters and Holders are in place and are recommended during use to provide an even more assured connection if working in busy environments.
