Is there any difference in focusing speed or accuracy between 1D and 5D if a single AF sensor is used (not cross type sensor) and one shot mode? I would be interested to hear the differences both in good lighting and bad (like EV3) lighting.
5D is specified to focus to -0.5EV and 1D to 0EV. I think -0.5EV with 5D is due to larger AF sensors. Larger AF sensors would mean faster autofocusing at least when the light or subject is not that good. On the other hand, larger AF sensors might lead to AF errors since more subject area is covered by the sensor. 1D in turn has a lot faster AF processing engine so that should help autofocusing faster and better at least when the lighting is rather good.
I am a 5D user who considers 1DII. 1DmkIII feels a bit too expensive but is tempting because of more and better placed cross type AF sensors.
