--Left focus repair 1: returned unchanged. I got the "don't send it back because Japan is..."
--Left focus repair 2: returned with severe front focus. +20 fine tune helps a lot; not quite enough. Left sensor appears fixed.
-- Front focus repair number 3: Returns with the exact same front focus problem. Camera focuses about 4 inches short at 3 or 4 feet. Left is "ok" but now right sensor is a bit off.
+ 20 required on Nikkor 50mm 1.4; 24-70; 14-24; 105 2.8, 28-300.
I have finally figured out what must be happening: Canon has planted a tech at the Nikon repair facilities.
No idea what to do next. I've never been so disappointed in a product. Time to sell all my Nikon stuff and move to Canon? (jo)
