Seems to me that you've just discovered the mirror box in the SLRs. Good for you ;)

Please feel free. Enlighten me and all the other posters on DPR and fredmiranda. You said mirror box - where - how - what ???

PS: I presume you have followed the debate and know what we would like to get an answer on.

So, is it kind of reflection?
Anybody who do same things with other cameras? :)

Inside of an SLR camera.

Please forgive me, but it's just that I remember similar conversations in the times of usenet forums and film cameras, about fifteen years ago.

... a reflection caused by the protective piece og glas on top of the image censor? This piece of glas has some thickness and therefor an edge of which you could have something reflecting. The double lines could even be explained with an chamfered edge on the protective piece of glas.

This explenation is supported by the fact that the shadow is in top of the frame when the light is above the camera and vice versa. With the light above the camera it could be shining onto the bottom edge of the protective glas causing a reflection onto the bottom of the censor / top of the picture. I can't explain why it shows up as an hard edge in the top and soft edge at the botton (and why this is vice versa on the D610).

It seems it happens with about every current camera so far, maybe with exception of D4/s, at variable degree.

I don't know, maybe going back to photography could be a good alternative, or just give up on photography altogether.

Meanwhile, how about someone with a Canon dslr here test it?

;-)
 
I tried yesterday night with my 70D but couldnt replicate it, used a 50mm 1.8 and the lightsource was a desk lamp

dunno if this is the right way to test it though

Doesn't occur on my D800. Also tried it on my Canon 5D and didn't see it although the body doesn't have LV so it's harder to check it as carefully as on other bodies. A poster on FM took a 60-photo series and the effect showed up in 4. IMO the extent of the issue should be determined before we rush to categorize or dismiss it.

I noticed the issue on a trip to spain last month. It is a real issue, no doubt about it. It´s not lens flare. I made a video to prove it. In the end i show the pattern of my flashlight, with shows as a reflection on the camera.

Said persons performed the test using a bulb-type desk lamp. See, I don't have a D750 (or any DSLR). I'm just relaying the message, so would you be so kind as to point your gun barrel elsewhere?

Gun barrel? What a laugh. There was absolutely nothing wrong with my response to your post. If you are that thin skinned as to perceive that any counter opinion posted is a blast of criticism at you then you shouldn't be posting. I made absolutely no critical remarks against you. You relayed a message... I responded with my opinion of what was reported in the Asian blog.

Good sir, I don't exactly have a problem with you (and in all honesty, I wouldn't want to have a problem with you), yet it appears that you have a problem with me. Thus I invite you to sort out whatever problems you may have against me through private messaging. Thank you.

Where did you ever get the idea that I had a problem with you. Point out exactly what I wrote that upsets you. I wrote nothing against you or your character. I have nothing against you nor did I have anything rude to say in response to what you wrote.
 
Was in the market for D750. After reading this, I thought that maybe I will go with D610. Apparently the D610 replicates the same condition. Not wanting to go back to film, I think I will continue my quest for the D750. What a can of worms that has been opened!!!

Now for the BIG question that will likely start a flame war:

Did you buy your camera to take wonderful photos, or did you buy your camera to do forensic engineering and document all the design compromises that were made?

Go back to the very 1st posting on this subject. Images taken during a wedding were ruined because of this behavior. Would you argue against learning the characteristics of the tools?

There is a chance that not all lenses will do that on a D750. We now know that a few lenses can.

There is a chance that a lens hood might not be sufficient to protect against the behavior, and some additional tactic could be employed.

There is a pretty huge chance that the same thing can happen on other bodies.

It would be a good thing to understand which lens/body combination might need some extra step, and when. Or, forget about that. When it happens during a wedding, no problem, we'll just reassemble everyone the next week and repeat the poses.

The question bigger than yours is, do you like to have control over your craft? It's not required you know.

So far, I've only seen videos of the LCD [taken w/ a second video camera]. Why has no one taken a picture of this "problem"? Or thought to go to video mode and use the D710 to record the video?

I wonder if it's an issue with the LCD?

The D610 does not behave identically to the D750 I belive. I have to really push it to get the reflection or shadow. I've succeded doing so with a LED spot ligt. I can't replicate this under halogen spot or normal light bulb.

The other differance is that the hard edged shade is at the bottom of the picture in the D610. The shade on the top of the picture is harder to provoke and it is less distinct.
 
The more I consider this as the actual reason the more convinced I am. The edge of the protective glas would be able to cast a shadow / reflection in a very straight line and even showing two lines. Still can't explain why the one side is soft and the other very hard.

Okay, but then where do you go? People have reproduced the phenomenon on the 800, 810, 610, Canon 6D, and Fuji X-T1, and that's just in this family of threads. If people are fed up with/don't trust the 750, fine, but then where do you go? A7 family? Those have internal reflection "problems" too. 5D Mark III? I have a suspicion it can be provoked there, as well.

I am a 750 owner, I acknowledge that this phenomenon exists, I can make it happen on my camera + 50 1.8 G, but all the evidence in this thread and others suggests that this is not a 750 specific problem. Given the immense number of people who have said "MY 750 DOESN'T DO IT!", only to come back and say, "hey, actually, I can make mine do it," would you really trust your results if you got a "good" copy?

Again, I'm not denying this is a real thing that has ruined some pictures. But what do you do? Where do you go? The idea that replacing it will yield a better copy doesn't seem to hold any water, especially considering all the other bodies that can give you nearly identical flaring. What camera do you buy to "fix" this, if not the D750?

My video is from the camera - it's not from a second videorecorder. Its visible in LV and in pictures (but not in VF). There have been plenty of pictures with this issue start with the four pictures taken by the wedding photographers.

Well,the only one that i'm sure doesn't have the "issue",at least under the same conditions is the D4.

But I'm also sure that if i tested the D4 under several scenarios,something would show up!

In the meantime I'll keep the D750.I really like it has a 2nd/light camera to my D4.

I may be wrong,but this "issue" seems less problematic than the D700/D3 "blooming".And i used those bodies countless times to shoot on stage performances.
