Have you provided any footage from your camera to our support team? I may have missed where you shared those images in this or another thread but we would be happy to assist you if you could send those into our support offices.


I'm glad officials from BMD are now talking about and acknowledging that there is an issue as the silence was very frustrating. Thank you for responding and I hope that there will be status updates, even if there is no new information, once a week or so.

I have not. I've looked at 2 4.6K's that both exhibited the issue, and that made me hold off on my purchase. They weren't mine so I don't have footage of my own to provide, though I know the owners have contacted support. I had actually placed orders at 2 dealers and canceled both when this problem was reported in the production models (after also being reported in beta footage but never addressed). I'm currently looking at other camera options since it appears that every 4.6K has this issue to some degree and I cannot shoot and deliver footage with these kinds of problems. Hopefully your engineers will figure out and solve the problem before that happens as the 4.6K meets my needs and wants more than any other camera at the moment (minus the image issue). Thank you for following up.

Tony,
If you don't have answers, why is BM still shipping product? Especially when a large percentage exhibit the problem? I just seems so slimy.

I can attest to the fact that if your having any issues BMD is interested and will communicate with you consistently. I have a bit of a different issue than magenta corners but they have been in touch with me almost every day.

Luckily my issue only flares up in a very repeatable but rare situation, other than that the camera is doing amazing.

I wouldn't call Blackmagic slimy, but Tony, I have to agree with Ron. Why is Blackmagic still shipping? I understand I am in no position to comment on someone else's buisness practices, and I understand that you don't have the authority to make such a decision. But I have been through 2 cameras now, I have friends/coligues who have gone through cameras. It does seem slightly disturbing that a company would continue to ship a flawed product. Any insight would be helpful, thanks Tony.

Hello,

I am the owner of the camera with the serial number 2911... . My camera also has this uneven magenta thing most pronounced with a walimex 16mm. It is gone with a 300mm lens. Even at F/16.

But thats not the worst problem of my sensor. My camera also exhibits a green patch in the upper left region of the image. Its a green streak, looks like a comet or something like this. This is visible with all lenses and without a lens. (on top of that, there are some magenta "hairs" in the image)

And now here is the most important fact about this issue: This streak can be seen when looking at the sensor at the right angle! So it can be physically seen on the sensor surface!! The green is of the same shade as the centre of the image and exactly the opposite of the magenta corners. So this issue is absolutely related! Meaning, then issue has nothing to do with the IR filter glass.
It is caused by the sensor itself, or what is directly above it (micro lens array? some kind of coating?)

For me this seems to be a very important indicator to narrow down the cause if this problem.

I will try to attach two images that are showing this problem and the sensor surface.

Best regards,
Florian Duning

Until BMD starts testing every 4.6K camera shipped, the numbers in a recent Facebook survey indicate only about a third of users reporting magenta concerns. You might argue many of them just aren't looking hard enough or using problematic lenses, but while the 'bad' sensors are a very large number, there's still some rationale perhaps from BMD's perspective to keep shipping as most shipments will be 'good' cameras. I'm sure they've thought about putting shipments on hold, but that might disappoint a lot of shooters wanting the camera with orders made many months earlier. Not an easy decision either way until the reasons for the problems are better understood by BMD.

While the Facebook survey is hardly scientific, if the number of faulty cameras was 30%, I'd say that was way more than enough to not ship a product.

I think we need to wait for the issue to be identified before making that judgement though.

I was unable to attach the images directly (got a "Sorry, the board attachment quota has been reached." message every time), so I have uploaded them to my dropbox, because I think this is highly interesting stuff.

Does anyone else has some small or medium sized patches or strokes beside the "standard" magenta falloff?

Rick,
I really don't know. At least I wouldn't like to be a part of one-third of the BMD population having problems. I am not looking at things from BMD's perspective though. Why would I? I am looking at from MY perspective.
Subrata

PS: Every penny I spend is on my account, and I care. BMD may not care about its reputation to one-third of their population. It's their problem. I, for one, wouldn't be a part of that 33.33% of the BMD's problematic population. Unless I know things are settled and those minorities have a level playing field.

Subrata, BMD certainly cares about their reputation and their customers. That's why they are taking their time to analyze all these magenta-related issues before making definitive comments and announcing solutions. I think some at BMD might have got off to a bad start when the complaints started coming in, but now they should all know it's a serious concern and not operator error or their 'look.' I know what you mean as it can be considered cavalier or callous to send out problematic cameras. But I think they must feel they have no other option at this point while they ascertain the situation.

"No other option"? How about not shipping! History shows that this is the modus operandi of of BM. The BMCC, BMPC and BMPCC all had major issues. Just keep soldiering on and pretend there is no problem. Fix it as you go along, and keep the returns to a minimum with BS. Did they ever own up to the FPN on the BMPC?

I for one am glad they didn't stop shipping. My camera is not displaying any of the problems associated with this thread. And I'm not alone. However, I realise that doesn't make it any less disappointing or frustrating for those that are experiencing problems.

Thanks for the update Kristian Lam, it's good to hear that BMD is working on the problem.

Since this magenta problem is the biggest issue (along with FPN) with the UM4.6, could you please consider creating an official BMD post for announcements, even if the cause and solution are not yet fully in hand? (even a locked one would be welcome) This original post has become such a big thread that finding anything official from BMD in it can be challenging at best. Thanks and I hope the understanding of its cause and a full solution are near. This camera is just too good to otherwise let this condition be just the way it is.
Thanks!

I'm always very happy with reports of problem free cameras! Tristan have you used any of the lenses listed below that are known to cause the magenta corners issue with many other users cameras? And if you have, have you shot at F/T 8 or higher?

What about FPN?
I was experiencing a lot at 800 and 1600.
Are your cameras all FPN free?... I just would like to know if I'm to expect this on darker sides of the frame.

I have a PL model, so most of those lenses are incompatible.

The only lens on that list I've tested is the GL Optics (Tokina) 11-16mm. No strange corner magenta problems.

I've tested my CineAlta primes - specifically the 35mm @ f5.6, f8, f11 & f16 - without problems. I'm getting minor lens shading, but nothing concerning.

I shot a corporate film last week using B4 mount & B4 lens with not magenta problems.

Not sure if I'm correct about this and there are probably people that have a lot more experience and would be able to debunk this theory, however surely its just the lenses that are vignetting a little bit. The fact that the colour science leans more towards magenta means that it shows up more in the darker area's.

So if that was the case and the camera naturally had a slight green cast, it would be a faint green vignette.

I know this doesn't explain the uneven casts people have been mentioning, and maybe someone might shoot me down with this but thought I would put it out there.

The 4,6K sensor is much more prone to magenta (with lights and sensor correctly balanced) and this is mostly an issue when you have severe color cast and you need to immediately deliver ProRes straight from the camera.

The magenta corners we all complain about is fall-off to magenta on corners and sides (right side much more than left). This has nothing to do with lens vignetting, as it does appear also on fullframe lens.
This phenomenon is very evident when using lens stopped down above f8.0
Using a Sigma 18-35 f1.8 you'll get strong magenta corners when using it a 35mm: where this APS-C sized lens give the largest sensor area coverage
The results is a frame with very strong magenta on all edges while the center will be well balanced. Trying to fix by M/G slide will results in a greenish picture (in the center) with magenta sides.

The PL mount cameras seem to be free from this issue so far. (does anyone know of one?) Are the Cine Alta primes telecentric? One thought is that telecentric lenses will not produce the problem.

Emilian has a URSA Mini 4.6K PL and has reported magenta issues. That's the only one so far. As for people reading these forums, I think less than 1% have PL mount and PL cinema lenses.

If it were simply the case of an overall cast being accentuated by darker corners due to regular lens vignetting, then we would see the problem at wider apertures like f/1.4 and f/2 where most lenses vignette. In those cases, we do see the darker corners that you'd see at those settings with those lenses, but the darker areas are NOT magenta.

Instead, the problem creeps in around f/8, when the light from the lens is hitting the edges of the sensor at a steeper angle. That steeper angle is interacting with the lens to create a green deficiency that increases as you get closer to the edge of the sensor.

Also, on a lens like the Sigma 18-35, the issue is gone at 18mm, but there at 35mm even when the aperture remains at f/8. So it is likely about the angle at which the light is hitting the sensor, and perhaps the micro lenses on the green photosites specifically.

What concerns me right now is whether there are ANY good cameras out there. Ive heard about them, but I have never personally seen a RAW DNG of 35mm to 50mm shot at f/8 that didnt have some of this magenta vignetting.

Also Im not a hater, I just want to own one of these with a good sensor. In fact I will put my money where my mouth is. If someone has a fully working 4.6k cam, that I can test first hand to verify that it does in fact pass the test, I will gladly pay $6,000 for it.

Re: URSA Mini 4.6k The Original™ Magenta Cast Issue

PostThu May 12, 2016 4:29 pm

15 days ago I shipped my 4.6 for RMA, and today I received this:
"We have tested the camera in our office and found it to perform similarly to our test bench unit.
As such we would look to return the unit to you.

We are aware there has been some reports of a limited number of cameras experiencing unexpected behaviours.
This is something that we are looking into as a matter of priority and we can assure you that we are doing everything we can to get to the bottom of this.
We don't want to speculate or provide unrealistic or inaccurate information, so as soon as we have received accurate information we will contact you with further information.
"

So, this is how a URSA Mini 4,6K should normally look.


Now I really want to understand if people that already changed 3 cameras got replaced by BM or reseller.
Anyway, doesn't really matter, once here I'll return for refund.

Keep in mind that BM didn't aknowledge the issue. Even in this forum. They are just saying that "they'r aware of some reports from a limited number of users" that means nothing.

URSA Mini 4.6k The Original™ Magenta Cast Issue

PostThu May 12, 2016 5:06 pm

Doesn't make sense that your real image which is useless is supposedly the same as a benchmark camera being used by BMD. Just what are they shooting with the benchmark camera, and what lens, what aperture, etc.? I can believe the benchmark camera is one of the 'good' ones and if it is, how can they accept this right side magenta effect apparent in the sky shot?

Sounds like you received a standard 'form letter' that needs to be updated.

The only testing they would do on my replacement camera was the open sensor test. They refused to test it with a lens as I requested. The open sensor test is completely useless when it comes to revealing the magenta corners problem. Returning the camera for a refund may be the best option for anyone with this problem. Buying a new one again two or three months down the road, might yield a fixed camera.

That'd be pretty f..d up I'd say.

Can one ask for a report on the type of test being made?

That's really, really unacceptable. If I were you, I'd make this as public as possible and look into getting the Better Business Bureau involved. Even a civilian can see that the camera is not supposed to look like that. It doesn't even look like you abused the saturation to show the issue.

My camera is being RMA'd right now and this makes me very afraid...

As I said above, limiting returns with BS. Lets face it! BM had to know about this issue before they shipped. They had tons of beta testers and had to do extensive testing themselves. This issue is no surprise to them! They have been working on it for many months prior to shipment, and were unable to fix it. They shipped anyway. The sensor is extremely expensive. Look at the cost difference between the 4.6 and the 4K cameras. They couldn't afford to throw away the sensors, so they have dumped them on the unsuspecting customers!! The "keep sending us your shots" is disingenuous - it an attempt to create the illusion that this is a surprise to them. "We are aware there has been some reports of a limited number of cameras experiencing unexpected behaviours." What absolute garbage!!!

To argue that it's a surprise is to argue that they are incompetent. That's one thing BM isn't. Incompetent, no. Honest?

I'll not argue anymore, even because BM support is reading already yours, and mine, answers.
I'll be just *happy* to get back that camera and to review it in youtube and facebook side by side with BMPCC,BMMCC,FS5,A7R2,A7S,GH4 on same lens.
Viewers will judge by themself the statement "the returned image quality is within expected quality after the WB and tint correction" (first answer I got from support).

What make me really sad is that I'm feeling myself like an "hater" right now, but I'm really not.
I thought about myself more as a pioneer of new technologies, and I always forgive those early issues.

But dealing issues this way really scares me. Maybe cause I already owned an URSA big V1 with that bad FPN we all know, just to see it fixed in a brand new V2 one.

I think that BM couldn't exhibit at NAB'16 if they weren't delivering products announced one year before, even shipping them AS IS, for many two main reasons: press and users questions, new products from competitors. That's why they started delivering them two weeks before the show. IMHO.

So, if BM will fix this in, let's say, a couple of months, why should they change my camera if -again- "the returned image quality is within expected quality" ?
I know I have the best camera in the world to date, just need to not put on lens and keep shooting at a white wall.

I don't want to call out anyone specifically, but I have noticed that none of the beta testers have really commented on this once it became evident that it's a real issue.

These issues were visible in the beta footage but we were told not to judge beta footage and that we should wait for the final shipping cameras.

Now that those cameras are here, it appears that the issue is even worse! So I guess we were correct to wait.

Hey Gents,
Just a word of advice, deal with your dealer/reseller don't deal with BMD. You'll be able to return/exchange your camera in a more sufficient manner. I heard some resellers are not allowing individuals to return for the magenta issue, this may seem shady, but just wait an hour call back and explain that the SDI or XLR port is broken and get your money back or a new camera that way. I have a friend that learnt this the hard way. Early on he dealt with Blackmagic for an issue unrelated to the magenta, BMD sent him a new camera that exhibited the magenta characteristics, but he couldn't get his money back due to the fact that The camera was different then what his reseller sold. Now I'm not sure if that's just a technicality of him using a smaller dealer, or if they're all like that, just something to consider.

I haven't been so silenced by anyone other than those of you that spew personal venom and vitriol instead of trying to talk about the issues faced in a logical and scientific way.

Why should I engage with people like you ?

Either sit at home and peep with the white wall or go out and enjoy the camera.
BMD will solve the issue. In the meantime I will enjoy mine.

I need to learn how to best expose with this camera. Clearly different from how I worked with bmpcc. I will learn how to handle the magenta corners etc.

Others are out working with their new cameras.
That's what I think most regulars are doing.

I supplied my dngs and diagnosed my camera with same issues as others if I push the footage in unrealistic ways. But being angry and getting personal issues with people in public is not my cup of tea.

In Sweden, if you request warranty repairs etc for same issue three times during one or two years, you're eligible for full refund. I have plenty of time to wait for a fix. :)

JB, don't care too much. Many people learn from you and other regulars here. Valuable assets. Maybe people are frustrated and might see you as a representative since BMD says nothing and then unfortunately express harsh comments.

John - rest assured that there are those of us who appreciate your efforts, input and discussions.

I see 2 types of posts here - first is those trying to understand and help find a solution, and then there are the complain and attack posts....doesn't take a rocket scientist to work out which are helpful.

Seriously dude, where do you get off? Mr Brawley has been the single most helpful person on this forum for people learning about cinema camera use. And not only just about Blackmagic cameras, but any camera and/or equipment he has experience using.

He is not an employee of BMD, but a working cinematographer who we are not entitled to expect anything from. Yet he, like many others here, generously offers his time and experience for the benefit of all of us. This type of personal comment is absolutely unacceptable, not to mention immature and anti-social.

I don't see any attack of JB here at all. All I pointed out is that JB hadn't posted for quite awhile! Which, as John confirmed, was true. And he should be embarrassed at how BM is handling this! I would be personally embarrassed if I was a closely aligned with BM as he is! My criticism here is of BM, not John.

The problem here isn't the people on BM's case. The problem is BM. Obviously shipping a product with significant defects. And continuing to ship, knowing that it has significant defects, and by their own admissions, not knowing what the solution is.

See when you say this, I take this as a personal attack.

You're saying I'm some kind of attack dog. I'm attacked for not posting and attacked for explaining why I'm not posting.

You see how idiotic that seems right ? Your kinds of posts are why I'm not posting just to re-iterate.
