I've been reading a lot lately about some of the idiosyncrasies of the D300 autofocus system. For example in the D300 forum there is a post about the D300's ability to focus on birds in flight. https://www.nikoncafe.com/vforums/showthread.php?t=177146 I would appreciate learning from those who have used the D200 your experiences with that camera's autofocus. If you can, please let me know of particular strengths or weaknesses. Also, if this can be done without flaming each other, it would be great to learn about the comparative merits of the two systems. Thank you.
