On Nikon D750 flare investigated: Why we're not worried article (358 comments in total)
In reply to:

Ramjager: Let me guess if it was a Canon camera from DPR's perspective it would be another nail in the coffin.
Instead it's Nikon but hey it's ok...
Let me guess who is paying the bills..

But Canon has this problem too, did you not bother to read the post by DPR?

And DPR nowhere condemns Canon for Canon's failure, with a very expensive DSLR no less.

It's a minor issue for all SLRs involved and the high contrast of the D750 example pointed out the broader problem.

ozturert: Nikon should have ordered a lot of black dots by now. They will need them for D760, D820, D620, D900, D5...

ozturert:

No, the D610 is not the same.

Do you not apprehend the difference between a minor problem that affects few files from the bodies with the problem, a problem Nikon acknowledged, and a problem that affected every file in cameras suffering from oil in the wrong place?

So, yeah a really dumb old joke that many have already made.

You omitted the fact that the 6D and 5DIII also have this problem.

Charlie boots: If there are black dots in the tripod sockets then obviously Nikon knew about this before it was noticed by customers but they kept quiet until they had to do something. They should have been upfront and issued a notice and recall as soon as this was discovered. Once again Nikon does not inspire confidence in its new products. The result will be that people will hold off buying new products until the bugs have been ironed out.

Too many mistakes made in the past few years with high end expensive cameras without Nikon quickly taking responsibility.

Um, I believe the point is Nikon puts the dot there after servicing the body, before it's sold.

And then also puts the dot there after servicing a body returned to Nikon by a consumer.

Yes Z,

the colour problems with current compressed raw Sonys are pretty easy to see.

even some of these Kauai shots, the ones, extracted with ACR have trouble. now this could be an extraction time choice. i've never shot with the A7II outdoors (or on Kauai).

RichRMA: How are ISO variances addressed? A long while ago, I compared Olympus and Pentax DSLRs and found a marked difference in ISO speed between the two. The Pentax was at least a stop slower when it came to producing the same "out of the box" illumination levels as the Olympus. It's metering showed this difference, you had to raise levels considerably in post in order to get the Pentax to match the Olympus or expose longer in-camera. Raising levels in post of course had the effect of increasing noise which at the time (Pentax K10D) meant the Pentax wasn't that much freer of noise than the old 4/3rds Olympus sensors.

Rishi Sanyal:

"However, it's a common misconception that it's the ISO setting that leads to different noise levels. It's not the ISO setting but, instead, the actual amount of light captured. So these differences in stated ISO accuracy aren't actually very relevant to final image quality wrt to noise but"

Then how come I can shoot dark into shadows with the Nikon Df at ISO 3200 and see next to no noise in the raws, processed to tiff, while if I use the same camera in the same lighting but set the camera to say ISO 25,600 there's beginning to be noise?

Are you referring to some jpeg only thing? (Never heard of that either.)

Noise is definitely relative to how much the signal is amplified, whether on the sensor or later.

Now right deep shadows do add more noise to an image than the same camera shooting at the same settings in a bright environment. And this may be the factor to which you refer, but still upping the gain/ISO brings in more noise to the system.

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.

Andy Crowe,

Um, DPR recreated a problem already well documented weeks ago by Imaging Resource, an IR article DPR links.

davids8560: I highly recommend the Nikon D750. Still.

Mike FL:

Just since you don’t get the term:

“red flag”

means something that is obvious and visible, or known, well in advance.

Neither thing you mentioned would qualify as such.

And the stepped flare remains a minor flaw.

Mike FL: Where is the D750 sensor exactly come from?

Raist3d:

I disagree, but it's close.

The Sony RX100III has a good lens, but compressed raws aren't helping.

The Nikon 1 V3's kit lens isn't real good.

Now the Sony may have better dynamic range.

In reply to:

Richard Franiec: Thanks for following the issue.
Since Nikon recognized the phenomenon and they seems to have
a cure to counteract, I hope that Canon will follow Nikon's action and offer to fix their (my) 1DX which should have even more pronounced flare effect according to your findings.
Are you going to contact Canon regarding your discovery? That would be appreciated. Unless opening the the old can of worms could be counterproductive?

The problems with Canons have been known about for some weeks.

IR demonstrated this problem with all current Canon FF DSLRs, it's weakest with the 6D.

Good, now maybe people stop claiming that Canon doesn't have this problem, given the point DPR made about the 1DX.

Oh so ironical to learn that the only full framed DSLR that DPR couldn't get to create this really minor problem was a Nikon.

Just a Photographer: Expect the D760 to be announced At CP+...

f:

I think fixing in post is a bit of stretch with the 6D, unless the flaw happens to line up perfectly with some horizontal architectural element, with a shadow.

Indeed with every other camera the contrast step is less extreme than with the D750, but the images are ruined.

Now, the ones where the step in the flare is at the top or bottom certainly may provide the opportunity to crop the step out.

I'm not one who believes in blurring out blemishes. That's how a lot of photos are wrecked.

Mike FL:

You mean grey market, all D750s selling in the US were imported.

At the reputable camera stores in the US, the camera has been pulled and is still listed for basically list price, which is about $2300 for the body.

When some party offers a new item at 40% off what every reputable dealer is charging that is big red flag. Legitimate grey market imports would be in the neighborhood of 10% less--not 40%.

KenD100: I read info about black dot and red arrow point to tripod socket also serial no. I checked my d750's socket, look inside look like silver to me. where or what was black dot from? meant black socket? my s/n was 301xxxxx I read comment below s/n say great than 302xxxxx hmmm am not sure! I bought it last month. Also I already test shoot bright lights dining room and sunny day new car shines... I didn't see any flare... hmmm but this weekend I will test college baseball practice games I will see what happen.

I think the point about the black dot is that Nikon will put one in the 1/4"-20 threaded tripod mount on bodies Nikon has serviced, including bodies that Nikon pulled from dealer stock before they were sold.

The problem is not simply flare. It is a band of contrast within the flare. (Many DSLRs have this problem, but with less contrast.)

Imaging Resource describes the problem, and how to create it here:

Henri F: This is the beginning of an nteresting fight. Is Samsung going to pewn Pana and Canon when it comes to pro-level video? They sure managed to blow both Pana and Sony out of the water on the TV front.

BarnET:

Canon pro cameras shoot AVCHD+MP4, this C100 is 4K too.

http://www.bhphotovideo.com/c/product/889545-REG/Canon_EOS_C100_EF_Cinema.html

The G30, normal hi def, shoots MP4 and AVCHD, that's an excellent prosumer video camera.

fmian:

The D750's flare is NOT further into the frame than that of the Canon 6D.

Any file with an example of this stepped flare in it is ruined. That is unless you have really really low image production quality standards. (And there sure seem to be a lot of pettifoggers here who don't care about image production--probably should avoid a digicam gear website.)

Don't bother to try further misdirection.

marc petzold: Dear Nikon, you really do some very fine DSLR Gear, but please spent more time for Quality Assurance the next time before you'd release a DSLR body...

No marc,

I want to know when you'll be sending a message to Canon about all the Canon SLRs that have this problem of stepped flare? You know the 6D, the 5DIII and the 1DX.

Zeisschen:

"Widely known" from above refers not to a Sony camera. You seem confused on that point.

Links to Sony raws that have bad color from current 2013/2014/2015 Sony cameras. Pick any raw shot above ISO 400 that you want. It's real easy to see.

sfpeter: I'm as attached to a mirror as I am to whether you turn the on switch left or right. Right now mirrorless cameras are for the most part like advanced bridge cameras that can change lenses. Give me a mirrorless that is full frame, has the picture quality, battery life, and performance of a DSLR ad I'd use it. It HAS to have an EVF, and really the only shooting advantage I've seen is the display shows more clearly what the end result image will look like. Otherwise I keep feeling like mirrorless is the tablets of the camera world, something manufacturers tell us we need but we're not too sure yet.

sfpeter:

And "advanced bridge cameras that can change lenses", so you're not actually familiar with mirrorless offerings.

A good EVF is easier to use in real low light than even the best prism full framed SLRs. But good EVFs have only been out for less than 2 years.

theprehistorian,

Right lens sample variation could be more serious. I'm not real aware of Nikon's failures with that. But I'm sure willing to believe the problem exists.
