Why is the GRDIII lens sharper than the GRDIV

If you own both these cameras you can see the difference for yourself. The GRDIV does focus faster but it does not nail the sharpness that the GRD III does. I also find that when shooting with the GRDIV in good sunlight I will get “purple blobs” randomly.  I’m not sure what the techinical term for that is? I don’t get the purple blobs with the GRDIII?

I remember years ago when I was purchasing a GRDIV from B&H for my wife we ended up returning the camera twice because of this. I even showed the guys at the return counter the difference. Taking one shot with the GRDIII & then the GRDIV and comparing. They agreed that it was unusual and looked to be the case. Both those GRDIV’s created the “purple blobs” as well.

Anyone else familiar with this anomaly?
