Some of the BIF shots from Sunday. It was a cloudy day with very little light to work with. Not ideal for this lens
I used both Canon 5D3 and 7D
For 5D:
I started with Zone Auto Focus (Center Zone) - It did NOT go very well. Unless the subject is hitting the center point of the zone... Camera/Lens was missing the subject (absolute no movements)
I resorted back to the Center Focus Point and this seems to be the most reliable option for bird in flight. Camera/Lens was able to focus - I guess it was comparable to my Canon 400mm 5.6 with 1.4x III extender (which is not bad I guess)
My setting for AI Serve, Continuous Hight Speed shooting, Center Focus Point, Case 4 in the AutoFocus settings, Lens drive when AF impossible = ON
For 7D:
I started with the zone autofocus and camera continuous focus on the subject but subject stays out of focus in most of the shots (probably require Micro Adjust)
I did not get the change try with only the center point but guess that should work fine - its just the zone autofocus had some issues.
Still early days, I am still trying to understand the lens behaviour in these situations. I am OK if the behaviour is predictable as I can plan for but.
