Does anyone know which is the best Infrared filter to use? Opteka or Hoya?

Question

I'm looking to get into Ir photography but I'm finding it hard to choose a filter. I'm shooting with an xti with 70-200 F4L, 50 F1.8, 17-55 F2.8 and 60 F2.8 Macro. I have step down rings and all but I want to find the filter that gives the best results. I see 720 NM seems to be the most popular but im not sure what that will give me. Does anyone have any sample shootings times and sample pictures? Thanks

Answer 1

The Hoya R72 and similar filters are the most popular because they block out almost all (if not all) of the visible range of light, leaving you with nothing but infrared light.
