5D4 Sensor Defect Discovered

[takesome1]

This issue could be normal behavior, it could be a few defective units, or it could be a major issue. In that last case, there will be a recall for affected units.

All valid reasons to NOT buy the unit at this time.
If it is a minor issue it will play itself out and in a few months then buy one.

It reminds me of the 24-70mm II problems with copy variations and clicking noises. It is a great lens and people still buy it.

If a few reports of problems on the Internet constitute a reason for you not to buy something, you'll never buy anything. The 7D was 'soft'. The 7DII has 'focus issues'. The 5DIII had a light leak. Of those, only one was an actual widespread problem, which Canon addressed.

I bought a 24-70/2.8 II during the 'problems', my lens is just fine.

This is pretty nasty banding to be honest. And it seems like a lot of people are experiencing this "problem".

I won't be buying one now until after the new year.

That's a safe bet. I made the mistake to buy too soon. I didn't have any problems with my previous cameras (5D2, 5D3) simply because I waited.

5D2: Needed firmware 1.07 to fix dark spots near bright ones.
5D3: Needed an insulation tape to stop metering being affected from light during night exposures.
7D2: Many units could not focus correctly

But the reason I waited was that I did not want them initially:

I upgraded to 5D2 when my 40D was stolen (plus I already had many FF lenses...)
I upgraded to 5D3 when I didn't think any more that 5D2 was equal to 5D3.
I got 7D2 when I started shooting birds and I was FL limited.

On the contrary I got 40D - my first DSLR -from the beginning but it was 100% OK.
I had an excuse that I wanted to start shooting digital and I was waiting for it (I even went on vacation two months before using my EOS1n - waiting for 40D)

I got 5D4 because I could not stop myself from wanting it!!!!!
In practice I could wait because summer was gone, so I did not needed it urgently for landscapes and landscape astrophotography. Also some DR demanding shoots would take place next May/June/July.

So I had no excuse for getting 5D4 that early.

That is very true. I didn't buy the original 5D not only because it was too expensive but because it was reported to be a dust pump. Maybe it was maybe it wasn't. But I could have shot many nice pictures in digital (like a total solar eclipse). On the positive side I used the money I saved to buy Coolscan 5000ED

...This thread started with the OP demonstrating some pretty extreme circumstances to show an effect most people would not notice in a long time of shooting. In the good old days it used to be called 'finding the limitations of the gear'. Now everything is 'a fault' or 'a mistake' or 'the manufacturer don't know what they are doing'. It is becoming increasingly tedious to tell the difference between a genuine concern and someone who thinks they have found something worth discussing...

...This not about being a fanboy or a Canon shill, but being bored with over-hyping issues (real or perceived) and people seeming less willing to discuss gear but phrasing things in a way that suggests the only thing that interests them is finding 'problems' with new gear.

Excellent post. I'm willing to entertain the possibility that this might be a legitimate issue. But, so far, all the examples that have been posted look to me to be very typical examples of pushing beyond the limitations of the gear.

The much-maligned DPReview gave very high marks to the both the 1D x II and 5D IV, but also said Canon's sensor technology still lags slightly behind its competitors. To me, a lot of the examples posted here simply confirm that observation. People are pushing the camera to its limits and getting some noise and banding. No surprise.

What intrigues me is the viral nature of how this supposed defect is being identified. Someone pushes the equipment beyond normal limitations and finds a "defect," which sets about a mass hysteria as others try to replicate the same conditions and conclude their equipment is defective.

It seems like everyone would be better off if they just took a deep breath and waited to see if Canon identifies a real problem, or if this is just a hoax. If you bought it new, it has a year's warranty, so no reason to rush to judgement.

What I'm saying is, unless you need a 5D4 right now, why not wait and see how this plays out before shelling out a lot of money on a camera?

Anyone remember the banding/exposure line issue with the D750 when shooting into strong backlit scenes? For weeks people on forums said it wasn't a big deal and would only show up under extreme circumstances, and then Nikon issued a recall.

I didn't buy the original 5D not only because it was too expensive but because it was reported to be a dust pump. Maybe it was maybe it wasn't.

It wasn't Unless you used an external extending zoom like the 24-105 or 70-300 etc, then it was (is).

Underexposure 3ev then push up 3ev in LR, +100 shadow, and then the banding showed up.

So about a 6-stop push then?
How about you take a normal scene, not underexposed and then push the shadows 100%. Because that is what I would do in real life.
See how that works.

Actually only +3ev in LR, which means make the photo return to +0ev as the auto-metering of the camera.
I don't know how to get +6ev in LR.

Hello, I can get this banding by going +2 on the exposure and 100% shadows.

But only is the histogram is clipped on the left indicating there is no data there anyway.

Seems like a non issue on that basis tbh. If there's no data there all you do is get amp readout glow.

I bought a 24-70/2.8 II during the 'problems', my lens is just fine.

Reports that number in the thousands always start with a few. I think you had previously mentioned you wouldn't be buying a 5D IV, neither will I. However if I were in the market for it I would probably wait a month or two to see how reports play out.

The 24-70 II clicking noise thread still seems to pop up occasionally. It is a great lens regardless.

I own one of the 7D II's with "focus issues", it has been to the CPS twice and still has an issue. Since I have purchased two and one has the problem , the problem seems to be centered around 50% of the 7D II's that I have purchased from my point of view that problem is widespread.

But most of the time, reports that number in the few do not go any further than that.

I think maybe you're just a little bit biased there...

The bits that have banding are the shadows. You are pushing those by three stops then you are lifting the shadows again by 100% which is another 3 stops (or more). So you are pushing the non-shadows by 3 stops and the shadows by 6+ stops.

Done a statistics degree, have you?

I once kept had a cat that had been abused by its previous owner. It never trusted anyone, and never trusted me. From the cat's point of view all humans must be bad since its first owner had abused it so much. It is easy for the multitude of owners of happy lap cats to look at the abused cat and say the cat is wrong, but if you are the cat with cigarette burn scars your view may be different.

I had assumed you were being facetious. If that's not the case, you clearly lack perspective and objectivity. Does the earth look flat from your point of view, too?

Well of course not, it has hills, mountains and valleys to.

I have 2 kids, one of them was born with heart problems. The AHA and March of Dimes say it happens to 1 in 100 babies. From my perspective, it still happens to 1 in 100 babies, not 1 in 2. Anything else is ridiculous ignoring of reality.

That's not true for everyone... :-X

 

[ilumo]

actually, I take it back. I could reproduce it. but man, in real world, i would NEVER do this. would be interested to see other cameras with this same test. I dont think in my 40000+ 5d3 shots ive ever done this, even in a purely test environment. oh well.
