Follow-up: I went ahead and used both cameras today. Same strange color balance in the camera A jpg's. To better explain what I am talking about, here is a screen shot taken while downloading into Lightroom. The thumbnails shown have not yet had LR generate a preview and it's own version of a thumbnail based on the DNG. The first 7 of 8 thumbnails shown were taken in fairly rapid sequence as I was following five small boats across the scene, trying to get a shot with a good juxtoposition of the five boats and the lager sailing vessel behind. So all seven shots had the same shooting parameters. You can see the color variation in the thumbnnails.
