next PZ lens test report: Canon EF 24-70mm f/4 USM L IS
#13
Quote:You could of course suggest instead that the camera refocuses when you finally press the shutter button. However, that would probably lead to some sort of shutter lag.
There already is a lag time, due to setting the aperture. I once tried to measure the aperture movement speed of the Canon 50mm f/1.8 and concluded it was a little too slow for the full fps of the 7D. I don't know how much aperture settling time they allow, but possibly the minor focus nudge could be done in that time with minimal impact.
