I don't believe I ever actually said it was complete nonsense.
I might have said that I don't think it's a big problem. And I still think that.
I haven't seen it with my own BM cameras. But I also don't have cameras made on the assembly line and I know that my experience is not others experience either.
But many many other beta testers have cameras form the line. And there are many beta testers who don't post footage publicly. And a lot of that feedback is shared amongst the beta testers. And it wasn't really that much of an issue amongst the many that were beta testing.
So when I see people posting a shot as dusk that would naturally have magenta colour in it as evidence of a magenta problem then yeah, I'm going to ask if there really is a problem.
I posted an experiment with my own camera and I was somewhat surprised to see my stills camera does the same thing, if not worse. I invite you all to try it as well. Shoot a RAW still with no lens on.
But even as bad as my stills camera was, I'd never ever noticed it in the work I was doing with it over the last 18 months. I think that says something about the severity of this issue as well. Yeah you can make a fault show in the worst case scenario of a white wall with no lens. But does it make your shots unusable ?
There was a similar sensor issue when the pocket first started starting shipping. Sometimes there was an ORB in highlights or a kind of odd clipping. Next thing you know, people were posting shots of out of focus highlights as evidence of an ORB crisis.
I have a fair bit of skepticism when manufacturers tell me things like "hey it's got 15 stops" because I want to be able to prove that stuff to myself. I also have a healthy skepticism for problems posted by users that I can't see or document or repeat for myself. 9 out of 10 users with corrupt frames that start threads about how crap their camera is fro dropping frames, turn out to be bad docks or backing up and have nothing to do with the camera.
I think that this is the very first run of a brand new camera with a new sensor and they have some issues dialing things in. You know I read over on REDUSER that they have a 90% rejection rate on their new 8K sensors. It's really hard to make sensors (BM don't actually make them) and getting consistency from batch to batch and sensor to sensor is also really difficult. I don't want to preempt what BM are doing to address this, but if I had to guess, I'd say it's an issue of something like sensor to sensor consistency or calibration from the factory. I'm going to bet that it can be and will be reduced and anyone who thinks they have a problem sensor will be able to get it 'sorted"
I think that BM, as they have done with similar issues in the past, will happily address the issue via their service department. They've done it before and I'm sure they'll do it for this problem. They key is to be able to identify if you actually have a problem. So far we've already in this thread developed a good way of baselining each other's sensors. We can compare and see them in similar circumstances and therefore judge the severity of the issue. I think that's where a forum like this is super cool...
