So whether you are shooting at f/1.4 or f/8 the lens is always open at f/1.4 during focus acquisition and the AF system is operating at f/2.8.

Mike: Maybe this is a dumb question. What does this mean, the AF system is operating at f/2.8 even when the lens is open at f/1.4? Thanks.

Aperture is always wide open while looking thru the viewfinder and focusing, unless you press the DOF preview button. Once you take the shot the camera closes the aperture to the desired f-stop. It does not affect the AF. I have always found great success with AF with 2.8 zooms but not with 1.4 primes.
