I learned my lesson well from my D800 debacle back in 2012 because I don't even want to be paid to be a Nikon beta-tester. As the marketing machine at the full speed promoted D750, I just relaxed doing nothing. When practically new D810 labeled as refurb gets sold for $400 North of D750, I started to realize both D810 and D750 are obscenely overpriced for fan boys. If I really need any of those, which I highly doubt, for what I do, I probably want to wait for better prices after the initial rush.

Tried to reproduce with a 28mm f1.8G with either live view and by taking pictures and no flare here. I was about 2 feet from a lightbulb. So it is a no issue for me.
People, don't confuse this issue with a defect of the body, serial numbers are irrelevant. It is the lens that produces this issue. Some lenses will produce it, some won't. Circumstances must be quite specific in order for this flare to be generated.
JBPhotog, I do agree with you on that because the latest lens design coming from most manufacturers uses a flat field design specially catered for digital photography. With that I meant having a less convex and flatter inner element. And the 28mm f1.8G is one of them.
Also I suspected that there are more than a single issue, and the lens is one of them, and something else when without the lens.
But still would be good to know the range of s/n that were affected or seeing them.
I finally reproduced the horizontal flare boundary with my D750 using an LED flashlight. Mounted the same lens and exposure settings (50G f/1.4 @ f/1.6) on my D800 and don't see the boundary on it. I shot this using the LV movie mode on the body, which crops the frame a bit so that boundary is higher than the other videos that recorded the LCD screen. I also tried my Sony NEX-5N using a different lens (worse flare characteristics) and that produces several striated flare boundaries.
Snapsy, yes you were able to duplicate them on the D750 and your NEX-N5. The problem is the N5 does not have a focusing sensor at the bottom of the black box and still exhibits the same issue, so now is that the common Sony sensor and it's on board firmware?
Since you have both cameras, can you confirm if the focusing sensor is sitting shallower on the D750 than the D800? Or is the tilting angle slightly different?
Thanks!

If lens design is the trigger, why we can't see it on other camera body like D8X0,,D4(s)?
It must be a physical design issue of D750 and can't be fixed by firmware update. We might have to wait for another patch version for D750 (D760)?
dreamplayer, if you follow through the whole thread, you would have found the answers to your question.
Simply put, there are more than a single cause to this issue. Sometimes it needs a combination to produce it.
I was finally able to reproduce it with my 50 1.8g (No hood or filer on lens) using LED flashlight. Not able to reproduce using Nikon 24-120 F4 or Nikon 70-200 2.8 VR.
My unscientific conclusion is that the light leak can be re-produced on D750 if done properly, but you certainly have to go through a lot of trouble to do so. Since I don't shoot LED's all day, not worrying about it
In fairness, I have a D750 at home (in Asia now) but I am not a single but concerned on the issue. I have the lenses that don't seem to get this light leak issue and if I see through what trouble one has to go for creating this effect I can only say that this is of no real concern in every day life.
Should it happen? Not at all but again, one has to go through a load of trouble to get this issue on the pictures they take.
Secondly, I find it amazing how some people are so eager and hopeful that Nikon is making mistakes in their designs so they can moan and b***h about it, even from persons that did not had either a D800(E) or a D750 but like to bring up these issues.
It sure is a strange world out there.
I have a D750, I am not worried. I can't reproduce what has been reported (perhaps I am not doing it "right," and/or don't have a proper setup), and being aware of this possibility will make me more careful in composition while shooting opposite/under direct light. If I were in the market to buy a D750, I would still buy it knowing what is known. I understand for some pros (which I am not), the reported behavior can be troublesome, but then it appears to happen with other models/brands/lens combo as well albeit to a varying degree.
A few of those that reported the issue are professional wedding photographers. One even posted an image shot at a wedding where it ruined a recessional shot. I also shoot weddings for a living and am grateful for the posts, since I'm in the market to upgrade my equipment and can't have that happen at a wedding. We shoot towards the sun or bright lights all the time and I need equipment that works properly.
In the process of shooting weddings, portraits and covering events I typically don't employ the effect of lens glare/flare from strong backlight, personally it's not my style. That said, I can empathize with photographers who are going for that look if their camera produces that shadow line at the top of the frame. If my camera was affected, it wouldn't matter to me - I'd shoot around it. I shoot with hoods and filterless indoors and out to avoid glare/flare. But out of curiosity, I did everything I could to duplicate some of the results I've seen here, and I can't produce it with my 750. So I have to believe that my particular body is operating to spec.

Point the cam at a strong light source and tild the camera slowly up and down in LV. Once the light source leaves the images there is a small area where you get the dark band. It happens both in LV and with taking the image regular.
It happens at the upper BUT also at the lower part of the image! Though stronger at the upper part. So it is not a shutter issue, nor a reflexion of the mirrors/AF something.
It feels like there is a shadow been thrown by something (mirror box?)
I have good connections to Nikon Germany and talked to them. The chief of repair did not know about the issue. I sent him the images and await a reply.

After your photo examples I don't think anyone would argue a similar phenomena can't occur on other cameras. The discussion is situations where it manifests on the D750 and not on other Nikon bodies, using the same lens and lighting conditions.

In your first photo; whats the main source of light.
it's reflection, flare, ghost, light leak or anything else one wants to call it; I clearly see that it impacts the images in a one particular way.
It's clear that not all D750 are effected.
I too have suffered from this issue. But I don't think Nikon is going to help me. Pretty much because the camera I used, while a Nikon, was a Nikon F from 1970-something...
Nikon F, Voigtlander 40mm Ultron, Portra 400. Oh, and with a dose of lens flare. Remarkable how it looks like a "light leak" D750!
p.s. I had a UV filter on the lens. Should have taken that off. And yeah, this means I am firmly on the lens flare side of this debate.
