Looking for the above to use with the IR film I just got. Before I gamble with eBay, I will try here first. Also I do have some 3x3 filters, but my holder only accepts 4x4. I believe there are 3x3-4x4 holders. If you have some I am interested. My DIY skills are just above 0 so I am not looking to make the frames. PM me with what you have
