Originally posted by starbase218 You say liveview couldn't even provide an image for you to manually focus on, yet PDAF still worked?
You say this as if you think CDaf will focus in lower light levels than PDaf !!
CD af currently is no where near the low light sensitivity of PD af , That is why most manufacturers wont even give figures in the camera spec.
The ability of CD af to not need calibrating for accurate AF has lead to many false assumptions on it ability, It is still the poor cousin to PD af
CD is a one trick pony with no other advantage over PD than the calibration requirements.
Because of the high gain required for liveview it fails for even MF long before an f2.8 lens reaches -3EV
