I have the D7000 and an infrared filter, but conditions have not been right for a reasonable test. I'm not expecting it to work very well. Each succeeding generation of cameras has had better (or worse) filtering of IR wavelengths. Full sun exposures with the D300 were 30 seconds or more - and I expect the same or longer with the D7000. In comparison, my converted D200 has exposures at normal shutter speeds.
