Ran my 50 and 24-70 though FoCal today and did some shooting outside with the 50.
The 50 is totally out of focus @ 0 MA, @+20 is still slightly out with real shooting.
On FoCal the 50 said it needed +26 MA(was -2), the 24-70 needed +17MA @70mm( was -12MA.
seems they stopped the left side being soft now my centre point is Back focusing extremely.
Going to be a day of phone calls tmr to the shop, nikon and to get advise from TS.
The shop said they would not refund me when i purchased it if it showed the AF issue and i would have to send it to nikon..How ever checking the TS website you can demand a refund or replacement for faulty good within 6months and repair for upto 5 years(in scotland ,up to 10 in england) if the expected life is longer and its not user damage.
Will see if nikon try and use there normal impact damage chat with me.
