If there are leaves or branches between you and the subject, the camera/lens doesn't really know what you want. If there is a breeze, and said obstacles are moving, AND you do not have spot focusing on, the camera will hunt. Choosing action mode will do the same thing. Focusing looks for movement, such as a flying bird, vs a perching one.
I spot focus on the subject, moving the spot to something stable at the same distance as the subject off center of the frame. This frees up my composition wishes instead of centering the subject. Worked wonders with the hummingbirds yesterday. Pentaxian On Apr 13, 2014, at 16:08 , David J Brooks wrote: > Took the new 17-70 out to shoot birds in my lilac tree today.
