This morning I lucked upon a 1/2 dozen Common Terns fishing.
Unfortunately, had the 100-400 on the camera (1DMkIIN).
The lens struggled with smaller, faster and irregular flying targets.
Not only f/5.6 aperture delays the camera\'s AF response, the AF lens element group just moves slower than 400 f/5.6, 300 f/4 etc. I feel I would have done much better this morning even if I had the 180L.
I suppose one can get some keepers with just about any lens, however, the key difference is in the keeper rate and the effort one needs to put into it.
Thus, I\'ve come to the same conclusion from 3 years ago: the lens goes back to the stationary/slow target duty where it performs very well for me.
Here are three a bit more interesting shots with the 100-400 from this morning.
