I tested many of my lenses mounted on a converted 5D classic then later my 5D MKII that were both converted to IR (RG715) as well as converted Full Spectrum 5D MKII, Fujifilm S3 UV/IR and Fujifilm IS-Pro. Further testing with a filter (B+W 093) and then a Heliopan RG1000 on the lens. These were tested at various apertures until a hot spot appeared. Here are the findings I had. I added a couple that I use now.. Those with an * I find myself using more often than others.
