Okay let's get to basic first.
1. If I understood your reply, you assumed I or my friend uses 'Area mode' AF tracking when comparing the 85 f/1.4D versus the 85mm f/1.4G?
2. 50% that my shots are OOF? Meaning not focused to where I intend to? I get it focused where I want it to be. I shoot only in single AF point mode. If it is the eyes, then it is the eyes.
3. Based on my experience with the 85 f/1.4D, it acquire focus faster than the 85mm f/1.4G. But hit rate aren't as good as the f/1.4G despite being faster.
4. Depending on condition, sometimes the 85 f/1.4D can't even get a lock under low light, hunting compared to 85mm f/1.4G. To be frank, have you tried the 85mm f/1.4G and comparing it side by side with the f/1.4D before? If you did, you would understand what I experience.
1. Focus accuracy @ 1.4 is way better than the 1.4D under low light
2. Focus speed i think is almost the same anyway ( Way slower than 70-200 but not unbearably so )
3. Focus accuracy improves once stop down ( I guess it's the same for any prime lens? )
4. Sharpness for 1.4G wideopen is generally a bit better than 1.4D, but not shockingly better as the 1.4D is quite usable wideopen
My conclusion is same with CY, under low light condition the D version hunts and miss focus much more frequently compared to the 1.4G version, there's just no comparison at all
