Thks daredevil. I think although there are some perfectly fine D4 (plural) out there, it doesn't mean that others are fine. It can be the case that some users do not use a potentially defective D4 in a manner that will reveal the defect. Just like the D800, the issue is similar or even identical. The left side of the focus array is out-of-whack. Personally I prefer to call it an asymmetrical AF problem. I have been blunt in the past, but I believe my manners are still bearable. Feel free to flame me but to those of you who do not encounter such issues or have never encountered an issue that you feel is a defect, please be civil & empathize users who are affected by these problems. I am not alone. If you owned a D800 with this issue before the "fix" you would know how I feel, the experience is identical. Saying "never had any issues", or "my set is perfectly fine" without further discussion really does not help anyone. I think it is agreeable to acknowledge that Nikon QC has dipped a notch given the known issues of D800 and D600 (Oil stains/dust).
I know another friend who is also affected by the issue and has not gotten Nikon to admit the issue. To Nikon this is a matter of customer preference, and not a "defect" as I would very much like it to be acknowledged as.
Heres Nikon's Corporate opinion;
Nikon Tokyo told me that the D800 left AF point issue is a matter of user preference, so is the case of the green-ish screen, they are literally saying they enhance and tweak these users and they do not consider these as defects.
(Opinion here)
To me this is disastrous corporate behavior... but debatable whether admitting flaws on a regular basis like what Canon is doing nowadays is better behavior or not.
I have been to Tokyo 3 times and Malaysia once (my set was purchased in Malaysia). For a more in-depth view on my case you may visit my thread on dpreview (3 parts, 1st part long read);
