if he indeed did jump ship to Nikon now, I would be surprised since there were many people jumping ship to Canon from Nikon because of Nikon QC and dishonest customer treatment with its D600(which is now confirmed to be replaced).
Nikon did never issue proper FW update to the camera with many many FW related design flaws, and now it suddenly replacing it with a minor updated body.
this is really you know rude to us who actually bought a D600 camera or current D800 owners having experienced the infamous left AF issue.
they should have admitted these 2 overrated toy cameras actually have many hardware and software related issues and should have announced recalls.
But Nikon has never admitted it and just replacing them , it is really stupid , in the long run they will lose a lot of loyal customers who bought high end FX Nikon bodies and would have spent a lot of money into Nikon F mount.
Seriously that company is choosing to please wrong kind of cheap headed customers who just buy a cheap body and kit lens and all done, stupid.
Nikon betrayed us and even shafted.
I am still keeping at least two Nikon bodies (D800E and D600 for now) but I am not sure I will keep them if they really announces the D610 and discontinues the D600 without recalling it(for the infamous oily dust issue) or announcing real solution to fix the FW design flaw (it does not allow controlling iris in video mode).
Nikon is fraudulent and cheating all of its long time loyal followers like us , I think I was very right to have decided to go dual mount in last Oct.
Canon seems to be much better in QC dept and much more honest with its loyal customers.
