Sehr interessant. Kommt hier noch ein Folgeartikel? Würde gern mehr darüber hören. Kannst du mir per E-Mail eine Antwort geben?

[...] Beinahe hätte ich’s vergessen. Kurz vor Weihnachten hat Canon die ersten Exemplare der brandneuen EOS 1D Mark 4 an Endkunden ausgeliefert. Jetzt heißt es also erste Erfahrungsberichte und Testergebnisse mit der Kamera abzuwarten, denn immerhin war Canon in der jüngeren Vergangenheit unangenehm kreativ, wenn es darum ging, Fehler auch in hochwertige Kameras einzubauen. Zur Auswahl stünden da zum Beispiel ein hakeliger Autofokus oder schwarze Pixel an hellen Lichtquellen… [...]

Hello my name is Alex, and I own a Canon FS-100 camcorder. I mostly use it to film skateboarding. Windows Movie Maker is the only movie editor program I have. When I try to upload my videos on it, it says it cannt import this type of file. Do you know of any movie editor programs that is compatiple with my camcorder?

Here are some pictures processed from RAW and taken at ISO ranging from 800 to 3200.

Viewed at 100% crop, the black spots can be seen in certain high exposure areas like the light bulbs on the Christmas tree. However, not all high exposure areas show this “black spot” symptom. Seems like they only appear under certain conditions. In any case, i hope that Canon is working on something to solve this problem

Ed- agreed. Some CAs are harder to fix than this and are often visible without pixel peeping.

Here’s a link on something called “Black-Pitting”. As good a candidate for the problem as any, and likely fixable in firmware:

I did re-examine one of the 5D MK II beta photos that was available on the internet in both jpeg and raw at various ISO’s. Available Here (Huge File) http://www.akihabaranews.com/en/news-16901-Akiba+Interactive+Review:+Cannon's+5D+Mark+II+(beta)+RAW+Pictures+by+Night.html

It is a night shot with lots of bright lights. In all cases, I viewed them at 100%. They were not visible when reduced to screen size (24″ screen)

In the jpeg out of camera shots, I could see the black spots on a few lights. The very high ISO settings had them the most, 6400, 12800 and 25600.

I then converted the raw files using Adobe ACR, and the black dots were also quite visible as square black pixels, much worse at high ISO’s.

I then tried DPP, and right away noticed that they were less visible, but still there(NR at 0).

Finally, I tried sharpraw pro, and the dots were also visible.

Just to see what would happen, In DPP, I turned off auto lighting optimizer and put noise reduction of 8 luminance and 4 color and they disappeared. When I activated the autolighting optimizer, they came back slightly. At ISO 6400 and higher, a little noise reduction seems normal in any event.

For this photo, the black pixels were extremely minor and since very high ISO noise was a lot worse, using NR made them go away. Until I get my camera and do my own tests, I am not yet convinced that they are a problem.

I sent Canon an email regarding this issue. I am still waiting on my 5D2 to show up and wanted to know if they knew anything about the issue. They claim they have NOT received any complaints and said they did not have the time to read the mulitple threads center around this topic. Grrr!! I think I successfully got a support person with an attitude… So I am now waiting for their next response as I told them that was unacceptable answer. So my suggestion is if anyone is having problems with the black dots, to kindly send canon support an email with your photo. The only way this will be address is if canon gets a flood of emails… Here the link… https://www.usa.canon.com/consumer/controller?act=SupportMailerAct&fcategoryid=215&modelid=17662

Also I like to suggest that CR post an entry on the main page of the site suggesting that customers who are seeing black spots, to send Canon an email. Thanks.

So if Canon need to repair this , will this be a firmware job ? or a recall job ?

If it’s a recall i’m assuming a full refund will be in order ?

That’s what I think. Mine is perfect and I’m not usually that lucky.

I returned the crappy 50D a month ago. I preordered the 5D2 from Ritz 3 months ago and when they shipped it on Monday, Fedex lost it!
I think it’s a sign. I am sticking with my 1DIII which is still the best and a REAL professional camera.
I am NOT going to get a 5D2… Canon is messing up big time and they are paying for it. Unfortunately Nikon’s D3X is the best camera in the world right now with their proven quality at a price, of course. But the D3 beats the 1DIII in speed and quality as well.
Too bad I am not going to bail out on Canon just yet. But they better get their act together or they are going to keep losing customers…
I can’t wait for a 1D replacement ASAP. Canon needs it and PRO’s need it.
If things keep going like this, next Olympics or next World Cup all you are gonna see is big Black Telephoto Lenses…

I noticed the black dots on only 2 of my images, but very slight. HOwever, I noticed that when shooting an image, the left hand side of the images have blurred or unsharp areas.
Unbelieveable. How can this happen? Check your cameras for the same pls.
