Hello, New on here and this is my first post. After reading a lot on the web about the d7k IR issues, I ordered a filter for it anyway. Also being impatient, I ordered a D70 and filter as well. Before the D70 arrived I got to use the D7k with IR filter and was blown away with the images. After reading all the forums about it can't be done, I should've waited for the filter to arrive before ordering the D70. First day out with the D70 produced grainy noises shots with the first days shoot on the D7000 being far superior. I must add though I needed upto 3-4 second exposures on a bright sunny day with only a 720nm filter on.
