Magnetic Retro Color Filter Kit - Orange. I bought this with interest, but I'm selling it because I haven't used it much. I've used it 2-3 times. It attaches and detaches magnetically, and a magnetic adapter ring is also included. Please note that this is not the EVO system, so you cannot screw the filter directly onto the lens. If you don't have a magnetic system, screw on the included magnetic adapter ring first, and then attach this filter. Everything shown in the photos is included.
