I just shot a bunch of XC this morning and soccer this afternoon for the first time with my D300 and 300 f4. I'm very surprised by the number of OOF shots. I don't get nearly as many with my D200. I was using AF-C, A mode, SS were 1/5000 (give or take), monopod, and AF-C priority selection set to Release. I just changed 'Release' to 'Release+Focus'. I seem to remember Randy saying he has better luck with that. Anybody have any focus issues or tricks? Thanks.
