Re: possible solution

In my D7100 focus results table here, with both copies of the 17-50/F2.8 and the  50/F1.4,  I can see that using the left focus point in live view (CDAF) I get good sharp results for the whole image.

However, if I use the PDAF system by looking through the viewfinder and using the left focus point then the results are very bad for the whole image.

My question is does this point to an error in the lens or an error in the camera?

If it is the lens,  why would it work OK with the CDAF focus system in live view ?

Can anyone help me understand that in this case?

thanks
