5D4 Sensor Defect Discovered

[Loswr]

Kevin, thanks for bringing this to everyone's attention. I've noticed this with my camera as well and I'm glad you started a thread for all of us to compare notes on a new camera with unknown problems and limitations.

It's not your responsibility to write a post that is perfectly worded and diplomatic. You didn't say anything racist, bigoted or offensive. But, you did bring to attention what may or may not be a defect in some of the new 5D's. As we get more feedback from 5D owners, we can get a better perspective on what's going on.

Well spoken, Sir.

Even if you don't have six fingers on your right hand.

Start your car's engine and put the transmission in neutral, then floor the gas pedal for an hour or so. When it overheats and/or seizes, log onto a forum for your car make and post about how your car is defective. I'm sure your opinion will be warmly received.

Well spoken, Sir.

Was wonder how many people will really "purposely" under exposed an imaged and recover the exposure back to 5 stops and push the shadow by 100%?
Just curious...

I guess people still aren't reading...

This exaggerated what I'm seeing. If I dial back the push and the underexposure it's still there. This was only given as an example of what my particular camera is doing and shown to the extreme so that it's very obvious.

Well, enjoy your "real world" testing then

Does a 1 stop exposure correction with a +40 shadow adjustment sound reasonable? Because if you do and you use the 11-24 or 16-35 f2.8 MkIII wide open and you use lens corrections you have a total five stop corner lift.

Kevin, please let us know what comes of showing photos to a Canon technician, and what he has to say about all of this

I will! Canon doesn't like saying anything like "defect" or "problem", but they were quick to say what I'm seeing shouldn't happen...much to the dismay of the smartasses that have posted in here. Hahah

When I uncovered a firmware bug in the 1D X and called Canon, they said that shouldn't happen and since they couldn't reproduce it, I should send it in. I declined, worked out the root issue with help from another member of these forums, created a video demo and sent it to Canon, then they could reproduce it.

Point is, I hope they find it's defective, but they may tell you it's within spec.

In this case, you're drawing conclusions based on them having only your verbal description, not even pics. Put another way, if you rush a miracle man, you get rotten miracles.

Can confirm with my 5D4. 70mm @ f/2.8, ISO 100.

And... my camera has a similar problem. I was going to take it to a trip tomorrow and now I have packed it back in its case hoping the dealer will tell me to ship it back

Would using the latest version of camera raw make any difference 9.6.1 I think?

Edit:. Anyone able to replicate with DxO optics pro? I didn't upgrade to the latest version so can't test

I have tested with latest DPP (4.5.10.1) and I also converted the raw to dng. Even 5D3 gives a more tolerable result

But I have to admit these tests are a little extreme. The jacket is black! Even so 5D4 seems to have worse banding (in absence of a more precise term) than 5D3...

What are we supposed to be seeing here?

Can't comment on DxO Optics Pro, though I get similar results both in Lightroom and Capture One Pro.

Looks very good to me on a 4.75 stop lift.

Horizontal color bands in the 5D4 version. These do not exist in the 5D3 photo which is even more pushed.

The 5D3 version pushed even more does not have the color bands! Tue in the very dark small parts of the photos it has worse noise - that's 5D3 after all. But you can see the difference in the major part of the 5D3 photo.
