No an issue here, either. I took this earlier today -- while TRYING to make this dark band appear -- and all I got was some delicious flare.

just got info from 2 pros (im in contact with through FB) who have contacted a lawyer and are looking to take legal actions. one is a news journalist and will be making an article about it in the newspaper he works at. others said they might contact the legal offices of the D600 class act lawsuit. they want new cameras that are free from the problem. nikon has ignored their requests.

im just passing the information.

See the dark band? Not that pronounced but it is there. How would that AF sensor do that when I took this shot with the cam upside down?

Here are better shots:

010-3.jpg

011-2.jpg

The same light hits the lens at the opposite direction now.

Let's make it even easier to show why the AF sensor is problematic as a cause. Let's shoot normal but above the light source.

Light again hits my lens at the opposite direction and since it doesn't go through the lens flat as a pancake, how would that same sensor affect it now?

You tell me.

Btw, that line in the window is normal.

If I had to bet money on it, I'd pick the shutter curtain and say the stray light creeps through there. If the stray light bounces somewhere before the focal plane curtain, it could explain why we see that band of unspoiled area, an eventual increase right at the edge of the band, why upside down behaves similar but not identical and why I simply can't get this effect going sideways. It also explain why it doesn't show in the viewfinder.

It would also explain why the D3300 shows the same behavior during certain positions.

I did a mash-up of several shots:

That looks like my shutter curtain if you ask me.

I own Three full frame nikons and not one issue.

anyways got more info from the two pros who contacted me through facebook and theyre trying to get a class act lawsuit in order. this is what ive been told. not exactly sure of details.

Tell them to read page 455 of their manual first. They might realize there's no way they can win.

Not that I have a dog in this fist, but you don't have to actually go to court to "win", either...

....

They could try to settle but that's a path of no return in this case. Going to court and pointing out they warned about what could happen is probably much cheaper. Either way, I'll sit back and watch the show.

I think they might have contacted the lawyers who did the class act lawsuit for the D600. zimmerman and reed. not sure. they dont have to do much to win. its a very clean cut case here.

your fanboyism is a bit tiring jzee

I'm a realist. That is quite different from being a fan. If they want to go to court, more power to them.

Look, I know the problem and have the problem with my cam. I was interested in the problem as long as I didn't know what happened. I think it's the shutter curtain and until someone explains me why that can't be, I find the issue no longer interesting.

But what gets on my nerves is constantly being told what a crappy cam I bought and that I need to cry out loud to satisfy some drama queen that not even owns the cam and has all he knows about this issue from hear-see online.

If those that own it want to go to court or protest naked in Tokyo, good for them. I don't care about the problem or a fix. But quit nagging that I too have to think my cam is crap.

no one said its a crappy cam. Im not even saying it. you show me where I said crap camera. I think its a kick ass cam. Im planning to buy it, if they fix the leak. this is a severe issue I cant have ever show up in any job ill shoot. once they fix it, I, amongst many, will get one. I know a few people who will not buy the camera now. theyre waiting to see if nikon stands up and takes care of the issue. im certain they know about it. and well soon get some feedback from them, im certain.

again, I didnt think for a second the camera is crap. I think its great. just have an issue that for most wont be a problem in almost any shot they shoot. I, though, cant take any chance to buy it, now, till they fix it.

This isn't worth having words about.

If it is the focal plane shutter as I think it is, I doubt there will be a fix. When tilted to the leak angle, the light bounces somewhere before the curtain which at its furthest retreat when open blocks that part of the flare. If it was the AF sensor, it would not be as clearly defined since this is unfocused light. Fixing that would require finding a way to position it lower but then it needs to be faster to move the same distance. That is a lot of work and a whole lot more money.

There is already a fix for this and that is simply using something to shield the top of the lens. It's the cheapest and fastest fix possible. You can still shoot into the light or just below or above or anywhere needed and it doesn't hinder the field of view of the lens.

It's a silly problem and they should have fixed that before release but it's at such an angle it probably didn't even show up during testing. If none mentioned it, most of us wouldn't even have known this is happens.

The good news is that this is a non-issue for many..Just some isolated few that this is happening too..That batch was more then likely done on the wrong day where someone dropped the ball..This is def not happening to all D750's...So more then likely the few this has happened to will get fixed or a replacement eventually..
