Thanks for the info. At USAG meets any kind of flash is prohibited, so the strobes are out. The ISO on the D7000 goes up to 6400 plus the h0.3, h0.7, h1.0, and h2.0.( i need to do some reading to find out how high those are). I try to shoot at the lowest ISO I can, maybe next time I will bump up to 5000. At this meet I had the 70-200 on the D7000, and the 18-105 on my D40. I have permission to go any where I like at this meet, and it is in a 2 y/o convention center with very good lighting. Last year I shot with the D40 and the 70-200 and they came out pretty good. (I put together a lot of excellent info that I read on this forum to use, You Guys Rock!)
Thanks again, Greg
