I Concur With Frank. :-) Note: 720nm refers to which 'piece' of the IR Spectrum the filter lets thru. In this case 720 nanometers. You can get filters in a couple of different Nanometer Numbers. If you get into IR photography and like it, the different strengths give creatively different results. YMMV On the upside: Filter Acquisition Symdrome is a heck of a lot cheaper than Lens Acquisition Syndrome. R. in Mi.
