I found that on the D300 using the more narrow field of focus sensors works better when there are surrounding objects. Maybe 9. Like in the bird in the tree if you had 11 or 51! ha ha it was trying to get it all in focus rather than just the bird. Using the spot metering and focus will be "spot" on. In Nikon View you can have it highlight the focus point to see where you had it centered. The other thing Im still not certain of is that when I shoot birds in the water with some lapping waves if you have wide sensor area and continuous focus on rather than single the dang thing will keep trying to focus on the different wave heights rather than the bird. These things are smart but need human intervention to show them who's boss
You might know that but I thought I would throw it out.
I had a case of NAS (Nikon aquire syndrome) and trying to keep up with F5stop I got a 70-200 2.8VR for some indoor sports (I'll let your imagination run on that one) I tried the 14E TC but my test was during really cloudy conditions like we have had forever. I figure for the money and added mm the 17E TC would be better if the IQ stays up there. They did not have one in stock. Right now the best solution for reach is already in my bag. I bought the 80-400VR before the new 70-200VR was available. No problem on sharpness.
I sold my 10.5 and got a 16-85VR to use for most things. I have a huge 17-55 which is a touch sharper if you really test it, that I use for studio work.
Now if the sun would come out!!
