Re: Unfortuanetly the reoprts are important :*(

Gotta agree with you there.

The other thing I find strange is the statement we often see that contrast detect is more accurate as if this is to be expected.

Now when I went to school admittedly many years ago phase detect AF is many times more accurate if pre-calibrated correctly

The advantage of Contrast detect is it doesn't require additional hardware to function lowering manufacturing costs and is more fool proof not requiring pre-calibration.

The down side is contrast detect requires bags of light.

My test seem to indicate the status quo has not altered and Phase detect will continue to operate reliably long after contrast can no longer function, But this again seem to go against the popular opinion here (and seems only here).
