D2X 300/4 focus flight shots

hillrg · Jul 19, 2005

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.

I really like the last one, that should quite difficult to catch, that's not very big.

Well made point Rory (and excellent captures). 8)

Surely difficult to nail focus on such small insect in flight but you done it. Great work Rory.

WOW.......how do you do that? Good eye and a steady hand.

How do you track these suckers?
Good captures. Are they full frame or crops?

Those are pretty cool Rory, not the easiest to capture.

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.
