There has been quite a bit of discussion about the D2X focus aquisition compared tothe D2H. I have found the D2X a little tougher to focus than the D2H, but only a small amount. I took these photos with the 300/4 AF-S and TC14EII at 1/100s f/13 with fill flash at +2/3 EV. I would judge dragonflies to be a tougher subject to nail the focus than a bird flight shot. My success ratio was about 25%. I would have done better with the 70-200 + TC14 I think. View attachment 12300 View attachment 12301
They are minor crops - maybe 70-80% of the original. As to how - I try to anticipate where the dragonflies will hover and prefocus slightly farther away. The focus first tries to focus closer. If you start with too close focus, on such a small subject, the camera will usually go into hunt mode. Also, you need to practise centering the subject very quickly. I usually photograph with both eyes open, which helps to quickly locate the subject in the frame.
