Re: LiveView MF Vs LV contrast detect AF

but i discoverd that my 135L on 5D mark II is correct when in phase AF, but really and always out of focus in contrast AF in LV (i tried even to use Eos Utility to have a large image of the LV and i can confirm it's out of focus)

that's strange.. any solution?

I have not heard of contrast AF yielding out of focus results

1. the 5DII will contrast AF where ever you place the green magnify rectangle. Is that placed on an appropriate AF target?

2. AF target of high contrast lines, with good light.

3. Tripod to prevent unwanted camera movement

This should match optimum manual focus with Live View 5-10X magnification. Since LV is exactly what the sensor is going to record, it is a good way to evaluate the accuracy of the AF technique without taking an image.

I suppose there could be some reason for a systematic error in contrast detect AF, but I have not heard of it?
