define modern. all the 6MP bodies leaked IR badly. i have dozens of shots that show IR leakage and it was easily figured out because i was testing ND filters at the time shooting the same scene with several different ND filter brands. B+W filters didn't leak any. all the HiTech did. IR leakage is much more variable than a magenta cast. to further confirm, i shot with an 87C filter attached to compare IR leakage. just because the body's IR filter is lousy doesn't mean it doesn't exist. HiTech ND filters are essentially transparent to IR. that IR leakage translates into sometimes radical color shifts if you have a body that leaks IR.

Hogwash. In a side by side test tonight, with two identical cameras and lenses, and identical exposures with daylight WB, stacked 3-stop GND and 4-stop ND, the Singh's had a magenta cast and the Lee and Hitech did not. The Singh 4-stop ND is being returned. And this has nothing to do wit IR. Modern cameras have IR filters, IR doesn't get through. I know, I shoot astro, where we want IR and dslrs are pitiful compared to dedicated astro cameras unless modified. You can see the difference just looking through the filters and I don't have an IR eye .
