Could it be related to PDAF sensel pattern?

But some reports suggest this isn't an issue with the A7R...

Well, there is a chance that it has to do with either the spectral properties or some aspect of the sensor stack. I suppose the most likely part of the stack would be the microlenses. If so, it would involve a very specific interaction between that particular lens and the microlenses. I suppose there is a possibility that it has to do with the pattern of PDAF sensels...?

I have an A7 and have not seen this effect on any of my lenses so far... although I haven't played with all 130+ lenses I have on the A7 yet. The only other body I have with PDAF on the main sensor is a Canon EOS-M, and I haven't seen this effect on it either.
