Just got a call from my local Nikon repair facility. They have a lot of *new* EN-EL15 batteries for me compliments of Nikon Nordic and the D500 battery recall action. The recall had a limit of 5 batteries per customer and I filled my quota to the maximum.
Whatever the underlying reason for the recall, fact is I got a bunch of fresh new batteries instead of my old worn ones. For free. Good for me, the D500, D800, V1, or any other camera of mine using the EN-EL15. I had purchased a few of the 'good' version of the EN-EL15 already thus my camera battery bin is pretty much overflowing at the moment.
I probably will separate work flows so as to confine manual lenses to the Df and AF/AFS to the D500. Despite this division, there is nothing wrong with the capability of D500 to focus manually even very tricky optics such as the 50/1.2 Nikkor.
