5D4 Sensor Defect Discovered

I am trying to decide a possible course of action if there is still a problem in the new 5D4. I am thinking 1DxII but maybe this is an overkill... It will be very good for DR issues and action photography but for birds I would have to get closer (and weight would impact more since I would hold it more..). OK I will know in about 1.5 to 2 weeks...

You said that the 5D3 is much better than the 5D4 with a 4-5 stop push. Is the 5D3 image usable when you do that? If not, then the comparison is effectively nullified because you are trying to solve a problem that doesn't exist and the advantages of the 5D4 lie elsewhere.

The funny thing is it was an actual test pushing a black frame I think I had to push about 6-7 stops to see noticeable banding. I'm really not sure what scenarios I have to use to replicate this issue. I'm just glad that I don't seem to be affected.

Thanks Kevin- I'm amazed that you would get two copies that have the same issue. I'm also fascinated at how few 5d4 users understand the test and how to execute it (unfortunately you wont see it under those image conditions ilumo)

getting interesting poll results, so far it's about 50%.

Sorry. Haven't gone through all 15 pages. If you let me know what specific tests you need to run to replicate those results, I can try it for you guys. Maybe I can be the control.

If you read a previous post you will read that it is better in the larger part of the example photo. Still having the known shadow lift problems but in the specific example they were shown in say 1% of the area not in the 10%.

There has to be a very bright object in the left hand side of the frame, with dark areas to the right of it. Then when you bump up the shadows and exposure, there is the weird streak extended from the bright object.

i think that there is a too much generalization in this post. There certainly seem to be select situations where the banding flares up on SOME 5d4 bodies, but to say that the 5d3 is much better than the 5d4 when pushed 4-5 stops is complete BS and misinformation. The 5d4 in my experience and as tested by many people have blown away the 5d3 in LOW ISO DR. There seems to be valid issues on some bodies, but lets not exaggerate here guys.

Look at my previous post of the swing set in the park. I was trying to expose for the sky and it was still blown out (very bright) in some areas, and then I pushed up the extremely underexposed areas (shadows) on the bottom of the frame by +5 stops, and there was hardly ANY of the horizontal banding (streaks) that some of you guys were experiencing.

I think it only happens in low-light settings - I had a similar underexposed shot in similar lighting - outdoor sun - also scenarios where I had extremes in DR and pulled the shadows quite a bit - no streaking at all, and noticeably cleaner than with the 5D3. However, wait for night-time, take it inside in dim lighting and underexpose at low ISO and then you see it. It's rather odd, I'm not even sure I would have known about it had I not seen it reported on the internet/in this thread...

Also, your light source does not HAVE to be on the left side. I was able to reproduce the issue with the light on the right side, and even with the light source well out of the frame (although in that instance, it took a greater amount of pushing for the streaks to become visible)

An unfortunately long thread leading nowhere and back again.
This is the way I feel for some threads too but then if I do not like them I do not read them and certainly I do not make them longer by posting to them.

But you add to threads by commenting on comments about the length of pointless threads, so I'm not feelin' so inferior. 8)

What else could be said? The misleading, sensational title is obnoxious, but it keeps going and going with nothing new added.

I have not started the thread but the title is relevant. Of course HOPEFULLY it does not apply to all but some 5DIV sensors. May be OP could add something to make it more specific. The thread it helped me to find about it soon to send my 5DIV back.

Do you want to find threads that keep on and on? Find some discussions about how bad 5DIV is simply because it does not have tilting screen or because it has a 4K crop factor. ;D

Word. :)

Waiting on the tiniest discount...
