Here's a good comparison of the effect of different IR filters. They come from Eric Platt, a DPreview Sony Forum contributer. They were all on a Sony F717...

Hi, Ted! I don't think the metering is being affected because I always use manual exposure mode when I shoot infrared. The reason I do that is, the R72 allows...
It occurs to me that a part of my problem is probably attempting long exposure shots in windy conditions. I've been trying to shoot at ISO 100 to get low...

Shannon, I forgot to mention that I estimate the distance when manually focusing and then move the focus slightly in the IR direction(which is a little...
I was browsing through the files section and saw someone who is using a Nikon 880 and a Hoya R72 filter. I have a similar setup, and was wondering if rzmico...

Shannon, Yes, it is a few millimeters on the dial on most lenses but to be more precise it varies with focal length and lens. I have longth focal length...
