I am getting very sporadic results with the d500/tam. There is a definite discrepancy between the focus point I use and the focus point indicted in the image review -- the latter always one square below where I was pointing. The auto focus, which was astoundingly fast, is now only slightly better than my 5300 and certainly doesn't hold like it used to. I have a call in to Nikon and sent them images to see if I am nuts or what. If what, back it goes to the dreaded SquareTrade. . . .
