jtan163: @Rishi, BarneyI imagine the DPR staff have been discussing and perhaps dreading this question, so sorry, but I'd love to know.
In light (oh crack me up...) of this phenomena and the "revelation" (confirmation?) that it occurs in many DSLRs, will shining high lumen LEDs into the vicinity of front elements become a standard DPR review test?
It seems the genie is out of the jar now and I suspect a certain class of reader will want to know about this on all future DSLRs now.
"Standardizing AF and sensor tests, among other things" - truly an excellent news. Right now there's pretty much no place where people can find some good AF tests. Hope you'll make it!
nikheat: I checked my serial number (2004727) and the site says it is affected, but I have run every test I can and have read/seen and am unable to replicate any banded flare (not even a little bit).
So the question would be, should I still send it in? My initial reaction is no, how do they fix something that isnt broken? As I understand it, the D600 had a shutter replacement, but it seems the D750 only needs an adjustment.
Try testing with a different lens, shoot wide open. With some lenses effect is not visible.
Zeisschen: @ DPreview
Focus accuracy of DSLR still seems to be a problem with current cameras and manual calibration is still mandatory by the user, ust due to the nature of the system. Okay, you don’t have to send the whole body to the factory or go to the service like with a rangefinder camera, but compared to more accurate and service free on sensor focus system in mirrorless cameras it’s surely a bit of a down-side. Hasn’t the actual technical state of the art made this a clear CON in any DSLR that can't do this calibration fully automatically? I mean it's 2015!
"as they don't even know that this problem might exist" - if you don't know that problem exists than it's not visible for you, and therefore it's not a problem.
Move along, move along.
rsf3127: I understand that DPreview.com is not concerned about this dare issue because people there have not dropped two grand for the camera and do not rely on it as a tools to make their ends meet.I would avoid Nikon products until they decide to go mirrorless, because for me it is clear that they lack in the RD of mirrorboxes.
And if you're fine with camera that's lagging behind entry-level DSLRs when trying to focus then it is also ok if it is your money and not mine.
ozturert: This is really fantastic. Dpreview (Rishi) and HowaboutRAW have been trying to defend D750 when Nikon withdrew all D750s from retailers silently and issued a statement saying that they will repair affected cameras.I think you really need to meet Nikon executives and explain that their efforts are futile and they waste their money and time (which is money again).I'm also surprised (not joking, serioulsy) that 1Dx users have been unaware of this issue. Or have they been aware and not talking about this for years? Or is it really not the case for 1Dx and bigger issue for D750? This really needs to be investigated. Why has this issue been reported widely for ONLY d750 and not for d800, d810, 1Dx etc..? What can the reason be?And I cannot understand the logic behind saying "why we think that D750 owners can rest easy" when Nikon offered free fix? Personally I'd not buy a second hand D750 if it's not fixed by Nikon.
1Dx is the only camera where that issue was found other than D750.Nice that they got it to show the problem,but it's also skewing the reality into thinking that it's something common among other brands or other cameras. It's not.
Whatever it's stronger or not depends on a few factors: lens used (here we've got 1Dx tested on prime and D750 tested on zoom which adds even more to that), exact position of the light source, light intensity, angle at which it hits the lens front element (which again is different in both cameras),etc.
In either case: even though D750 got theoretical advantage due to the testing setup over 1Dx -from the samples published I see D750 having significantly stronger flare.
As for Howabout guy,he insisted that it's a binary operation - either photo is spoiled or not, stating that it's a problem with every DSLR so every DSLR will have photos spoiled. dPreview got quite opposite conclusions "we find it so slight as to not be much of a practical concern at all"-D810
David G72: One more thing, to anyone who wants to send their D750 for updating:
The fix to move the AF sensors down is complex and requires opening the camera, moving the phase detect sensors and re-calibrating the camera. When your camera comes back from Nikon service center, you might end up with it being worse than it was in terms of AF accuracy and reliability. If this flare issue does not bother you and your D750 is in excellent working condition, just forget about this and keep on clicking!!!
People are already spreading FUD about the fix.
Seriously David G72: Get a life, or find a better job than bashing products of competitors. Samsung already got punished for that.
Not until, but if. And If anyone got a problem with AF accuracy - it's usually a good idea to send a camera along with a lens to service for calibration. Also these days Sigma got quite an advanced software for fixing focusing issues, though as with everything - there always will be a few people who will keep on having problems regardless what they do.
In either case though - Full-size PDAF sensors are the way to go if someone wants to reliably "get that shot" and there's no alternative.
JRFlorendo: This is a SLAM DUNK class action law suit, an engineering flaw by Nikon engineers, can't get any easier than that. Nikon just needs to slow down, it seem like they are coming out with a new FF camera every six months, at that rate, something is bound to get neglected. Sony and Toshiba already providing you with top grade sensors, slooow down and get the engineering and quality control right.
Nope, they are not, and no, it doesn't demonstrate that "Canon has this same stepped flare issue". You are the only person who sees any stepped flare issue in "all current full framed Canon DSLRs" and you don't even own Canon. I got Nikon camera myself, but I don't see a reason to be such an aggressive apologist as you are, posting the same mantra under nearly every single comment.
"If you repeat a lie often enough, people will believe it, and you will even come to believe it yourself." - you believe it yourself already, but hopefully people are not.
Imaging Resource samples quite specifically illustrate that a visible stepped flare exists only in D750 and 1Dx, from which D750 got by far clearest issue, unlike any other camera on a market.
Here's the link so everyone could compare on their own: http://www.imaging-resource.com/news/2014/12/24/nikon-d750-flare-problems-heres-why-and-what-to-do-about-them-its-not-lens
Don't get fooled by Nikon apologists.
Lassoni: Did nikon provide "instructions" for people displeased with D800 AF performance? Other than "you should upgrade"?
"people displeased with AF performance"
Nope, just like Canon didn't with 5D mkII, Sony with A7r or Fuji with... well... pretty much everything.
"this is indicated by a black dot inside the tripod socket" - that's a very clever method of marking it. Good idea. :)
mgatov: On a recent trip to Disneyland, I observed that 95% of the cameras I saw people holding were DSLRs. I think their demise is premature.
A77 is not a mirrorless camera, so irrelevant to anything we discuss here.
blink667: If Mirrorless could catch up to FF DSLR AF speed, it might happen. But companies like Nikon and Canon and their wealth of excellent lenses at a third of the price of either Sony or Fuji are enough of a reason for many to buy DSLR.
I doubt. DSLRs got so much more to offer beyond AF speed. Actually - mirrorless in a way are already superior to DSLRs - they use much more accurate CDAF. This changes nothing though. Whole problem mirrorless cameras got is by far more extensive than just AF speed or C/N brand that people so easily point at.
golf1982 - depends on country-by-country basis. In some it's actually shrinking.
Tony H - "Many mirrorless look just like traditional DSLRs these days" - no, they don't. They look like a bridge cameras. With some others looking like an overgrown compacts.
mgatov - and what's wrong with that, again?
dlkeller: Right now P&S outsells DSLRs so this is not amazing. The issue is what happens in the DSLR type sector of the market.
"The DSLR type sector shrinks, because of the outdated and compromised mirror alignment and mirror slap issues" - clueless guy is clueless.DSLR sector shrinks because digital sensors matured and upgrading to the new body every 24 months is nowhere near as beneficial as it was 4 years ago. Mirrorless sector grows because it's a new thing that majority of people bus as a toy or their secondary body, plus the factor that from zero you can only grow. On a global scale - it's simple as that, really.
Plastek: So, who sponsored this trip?Because if it's Sony or anyone linked to Sony - you should clearly make a remark about it right before showing any scores for this camera.
Looks like he had a great time :)

Rooru S: Funny how we read an interview with a Samsung rep saying Mirrorless ILC market will get above the DSLR market in three years...yet Samsung isn't popular at all in Mirrorless market.
That doesn't make it a mirrorless. Mirrorless is industry-wide shortcut for naming mirrorless interchangeable lens cameras. Your smartphone isn't a mirrorless camera nor belongs to mirrorless market. Same with compacts.
completelyrandomstuff: What is pale blue between Pentax and Panasonic in CSC? Ricoh? Leica?
Samsung mirrorless share is too small to show on that graph.
(at the date of writing this comment best Samsung mirrorless got activity level of 1/10th to that of best Fuji mirrorless camera. Second Samsung mirrorless got activity an of 1/20th of second best Fuji mirrorless. Any other Samsung mirrorless cameras are pretty much non-existent while Fuji still got several quite active models)
