John Brawley Posted September 2, 2016 Share Posted September 2, 2016 23 hours ago, Kino said: I posted a sensor spec sheet from Fairchild that demonstrates how BMD uses off-the-shelf (or slightly modified) sensors in its cameras and does not manufacture its own sensors like Canon or Sony. You respond with insults and personal attacks. But please, carry on there . . . Can you buy the same sensor that is in the Ursa Mini 4.6K off the shelf and get the same result ? No. You can't. Is it an off the shelf sensor ? No it isn't. Do you keep saying it is ? Yes you do. Do you say stuff like "I think it has something to do with the fact that they source parts and do not manufacture their own circuits and sensors as with RED and the electronics conglomerates" That's your quote...you forgot that you said RED as well didn't you ? :-) Never mind.... So, you're wrong because RED don't do what you claim. Blackmagic DO make their own circuits and like RED, go to a sensor fab company and customise a sensor to their own specs that you can't buy. So do Arri for that matter. So how would you KNOW ? Seriously ? How do you know that it's off the shelf ? If it's only slightly modified, what does that ACTUALLY mean ? Is it the package size ? What EXACTLY is the benchmark for a slight modification ? What is it that was tweaked ? Was it one thing or many ? Did they just put the BM logo on it ? What other products use the same sensor ? Why doesn't someone else buy the same sensor and make a better camera ? I call you out because I've called you out before sir and I'm just cutting to the chase. You're wrong. Have an opinion. Don't post it as fact when you don't know if it's true. That's all I'm asking. JB Geoff CB, tweak and omar 3 Quote Link to comment Share on other sites More sharing options...

And for me, it's also about customer support and ergonomics and day-to-day strength of a camera - can it handle on-set abuse? I've had a UM4.6K for nearly a year. It's done many weeks of work on my sets. Most of the images in my twitter feed are of the same body, the very first one I got. I've had another two PL bodies for about 7 months that have also seen a lot of use. The camera can handle on set abuse. My main body has lots of scuff marks, scratches and dings. It's been rigged on a steadicam, Movi, to cars, in my hands, in production mode, in studio and remote locations. It's had extra transmitters, timecode clocks, plugged in, audio connections used, additional on board monitors, UMC's for remote focus.... There are many many sequences now in the last two TV drama series I shot that have Ursa Mini 4.6K shots and no one ever picks them. I managed to rip one helicoil out early on when an overzealous grip overtightened a rig. I lost a lock off screw that controls the tension on the EVF rotation. I've never replaced it, because the tension hasn't needed to be changed ! My cameras boot up, they don't overheat, they don't loose frames, my shots have passed a zillion INTERNATIONAL broadcast tech checks that specifically go looking for things like noise and FPN and image problems. Directors love the shots I can only get with an Ursa Mini 4.6K, so I'm going to keep using it.

Kino Posted September 2, 2016 Share Posted September 2, 2016 So it's just a coincidence that the BMD 4.6k sensor and the Fairchild 4.6k sensor have exactly the same specs and were released at the same time, right down to the switchable global/rolling shutter we were originally promised in the Ursa Mini? Having said that, there have been no statements from either company on where these sensors came from. BMD reps have claimed in interviews that the company spent $10 million developing the sensor, but that tells us nothing about what its relationship is to the Fairchild sensor that came out in 2015. And no one said you would get the same results if you put the same sensor into different cameras as there are so many other important components that contribute to the camera's image quality. The point was simply that BMD uses off-the-shelf sensor technology in contrast with RED and the electronics conglomerates. In fact, their CEO, Jarred Land, makes this claim about RED's sensors and boards: "We are the only company other than Sony in this market that designs both our own ASICs and sensors, so we can leverage yields in the manufacturing process to accommodate an array of products in different price points that all share the same DNA." http://nofilmschool.com/2016/02/red-scarlet-w-5k-camera-shipping Essentially, you are arguing against his position, which I have simply restated here.

Ehetyz Posted September 2, 2016 Share Posted September 2, 2016 I don't think Ursa Mini will be the end of Blackmagic, but as a long time BMCC user, all the problems that have popped up after its release have made me wait and see if any of the competitors can put out a less risky proposition. The magenta issue was bad enough, but people bricking the camera by having the side handle take a hit is what kills it for me. I shoot often in difficult environments, do action shots and generally things that put the camera at risk. BMCC never failed me at that, it's taken a 1,5 meter fall to concrete like a champ, twice. I have no faith in URSA mini being able to withstand that kind of abuse. The Mini 4.6K is frustrating. The image seems to be pretty much untouchable at the price point - but with way too many caveats and risks. Quote Link to comment Share on other sites More sharing options...

And for me, it's also about customer support and ergonomics and day-to-day strength of a camera - can it handle on-set abuse? I hope they can fix it with a firmware, because the camera does produce fantastic images for that price. It might not have the push/pull of arri exposure but image-wise it rivals it. The problem is that these smaller companies send their gear to these bloggers prerelease. Then you have all these 'professionals' hype it up, they don't want to piss off these companies who are giving them early access and a massive spotlight, so all their fans keep defending the gear even as problems slowly creep out of the shadows. It takes so much time and energy for the general user to fight off that fervor. I just don't see how they can fix it with lines of code when the problem effects each camera differently, some have stronger magenta corners than others. BMD knows what the problem is. They probably knew before the release, and it was probably one of the reasons why the long delay besides the failed global shutter. The customers who are buying the camera and using it already either don't care they are cutoff at f8 on certain focal lengths or are content lying to themselves probably won't effect BMD's business, so they should do the right thing and just clear the air since its already taken them a year to admit that the problem does exist.

Just out of curiosity unless you are going for mega depth of field why would you go past f8 on a super35 sensor? Sharpness really starts to drop at f/11 on a lot of lenses. I'm not trying to defend a camera flaw but unless I am being sloppy and not using the correct amount of ND I really avoid stopping down that much. I actually inadvertently discovered this with a film 35mm camera. I mean I knew about it theoretically but I thought it was just something pixel peepers worried about. Well I had a must get shot so I bracketed it at various apertures just to cover my depth of field bases and the results were astonishing. Sharpness at f/16 and f/22 was obviously less on a 35mm negative, not a print. Maybe people haven't worked with their camera much at f/11 and beyond. I never realized simply stopping down could reveal something like this magenta issue. I'll have to make sure I test all my future cameras.

Still, I think it's messed up if this issue was known by bmd and prerelease reviewers but swept under the rug to get it out there and see how it plays out by keeping quiet as long as possible. If you read through the magenta thread in balckmagic's forum an early adopter was being attacked for identifying this issue very early on, even pointing it out on some prerelease footage.

It just would never occur to me to point my camera at a white wall and stop down to f/11 when kicking the tires. My inclination would be to get the sharpest lens I could and open it up to it's sharpest aperture and then stress test the sensor. Having said that if I was buying a camera for thousands of dollars I would not be amused if it went magenta in the corners just because I visited f/11. Shame on them if they snuck this out the door with that kind of known flaw. Quote Link to comment Share on other sites More sharing options...
dhessel Posted September 3, 2016 Share Posted September 3, 2016 They knew or they are utterly incompetent, it was spotted in beta footage by a non beta tester just looking at footage. The mega thread on BM's form dates back to Sun Dec 06, 2015. It also can be found at larger stops that F8, it is just that 35mm at F8 is universally bad on the affected cameras. There were some who had issues at even F4 at 35mm. Hanriverprod and Liszon 2 Quote Link to comment Share on other sites More sharing options...

They'll outsource this part, just like BMD/Nikon/Canon/Arri/etc Land claims that RED is the only cinema camera company other than Sony that designs its own sensors and ASICs (integrated circuits). He makes no claims about where the sensors are fabricated. Of the cinema camera manufacturers, only Sony, Canon and Panasonic have their own sensor fabrication plants and have the potential to do everything in-house. Like BMD, RED would have to "outsource" the fabrication itself, which involves many steps, including the wafers from a semiconductor plant and the various other components that are then attached. The finished sensor just doesn't come from one place or even one factory. It's an elaborate process that is almost always outsourced for companies like RED and BMD. The difference is that RED designs their own sensors and boards and those are exclusive to them. You can't buy off-the-shelf versions of the Dragon sensor made by Fairchild or any other semiconductor company. It appears that BMD has to involve third parties like Fairchild in sensor design, suggesting that they don't have the same mastery that RED currently has. This lack of expertise may lead to problems such as we have seen with magenta-gate, considering how the sensor and its integration into the surrounding circuitry and the larger image processing chain would have to be designed with absolute precision. Perhaps they will get there eventually, such that they will have custom designed sensors that are exclusive to their products and not sold simultaneously as off-the-shelf sensors as with the Fairchild/BMD 4.6K. At that point, I would expect better quality control, which was the entire basis of our discussion. And, yes, it is entirely possible that BMD contracted Fairchild for the 4.6K with an arrangement to create two versions of the sensor: one for BMD and one off-the-shelf version. But the fact that they have to go to Fairchild would be proof that they did not design the 4.6K sensor on their own and do not hold the exclusive license or the patents involved.

Hanriverprod Posted September 4, 2016 Share Posted September 4, 2016 There is something off on the 4.6k image with this magenta issue even in the latest videos. I see it pop up on various shots on so many videos and it's not just the overall cast or magenta corners. It's in the way the camera handles highlights in some shots as well as edges. It might have more dynamic range but these issues make the 4k ursa look better overall. Ed_David 1 Quote Link to comment Share on other sites More sharing options...
