A neat filter trick

[Byuphoto]

I was having trouble getting filters for all my RF's. I use mostly Cokin with my SLR's so I was looking in the brochure and spotted a neat little gizmo. It is a bracket for digi-cams tha attaches to the tripod hole and extends in front of the lens, allowing the use of cokin filters. I ordered one and can now use my extensive collection on my various RF's no need for many different sizes. Here is a link to the product

Doesn't it get in the way of the focus and aperture ring?

I don't think you could use it with Leica or leica copies?
