Hi, I'm an ambassador for poor Matt Heitek filters. One of the things I love about them is they listen to when I have a problem and they try to find solutions. So we're here in sunny Bolivia, shooting a future vlog, and one of the things about this area is it's such bright, strong sun. So if I pile up a filter as I've got like an N-D-1.2 and a polarizer, the lights bouncing around all over the place, back down the lens, I'm getting double edges of highlights, and for me it's an absolute nightmare. So I asked them to find solution and this is what they came up with. This is a combined filter which includes N-D and polarizer in a full range. So now I have one filter, no double bounces, no highlights on the edges on the highlights. I'm very happy. Thank you for my Heitek.
