Just been thinking about focussing in AI servo mode (assuming you are a Canonian).
As the sequence seems to me;
1. Lens is at max aperture tracking the target whilst shutter button 1/2 pressed.
2. Fully depress shutter button, aperture closes and shot is taken at the current focus setting.
3. Aperture then open back to max to retain focus track.
My question is, if you are in "machine gun" mode tracking a fast object does the aperture open and close for each exposure to keep the focus tracking as accurate as possible.
If so, can really fast shooting (10 FPS) in a 1DMk3 actually shoot faster than the lens can open/close the aperture.
Are aperture times published anywhere for lenses?
Just my thought for the day
