3. In fact I was talking about something like shooting my daughter with 35 or 50 mm lens under sunlight with aperture at f/5.6 or f/8 from distance of at least 2-3 meters. I suppose I should have said this explicitly to avoid confusion. REPLY: The case is that if the camera AF is able to nail the shot with super telephotos with miniscule DOF shooting a 50mm lens at F:8 should cause no problem. Mind you, just like with MF it is important where you put your plane of focus. The 50 L/mm barrier yields no meaning in the shooting conditions you suggest. These test simply state that AF systems aren't perfect and given all the time in the world with properly calibrated cameras and loupes and god knows what, a person can focus more precisely. In the case 3. above theres no meaningful differences as long as you put the plane of focus at same place. P�l
