Canon 1Ds Mark II - red pixel issue

[hans1234a]

My new 1Ds Mark II has a very red pixcel (or two or three) in the right side of the frame. It turnes out in every shot, not so bright at faster shots but still there without a doubt. The ret spot is also there whatever iso, lens etc, although more saturated at higher iso or longer shutterspeed it seems.

It this common for the 1Ds Mark II?!

I have no place to upload an example, but the thing look just like the pixel area found in another discussion http://photography-on-the.net/forum/showthread.php?t=49203 Opinions? Experiences?

Anyone else checked their for red or blue spots?

If it shows up at long exposures and or high iso's, that is normal.
If it appears on all shots regardless of exposure time, I would return it.

[hans1234a]

Yup, it shows up at faster shutterspeeds too. Not that cricitcal but still there.

At this camera's price point, faults are not 'normal' or acceptable!

I agree, I'm attempting to purchase one of these too if I can get my hands on one, but if I had this, I'd return it. At the price, I'd expect excellence and nothing less.

Hey, who bought "mine" from bhphoto! By the time I got the OK to order they were GONE. ARgghh!

well there are over 16 and a half million photo sites.... one or two are likely to be bad :wink:

Return it if you can. Otherwise, send it back to Canon and they will map out the bad pixel(s) and all will be good.

I always wondered about this, and why there isn't software that can be configured to match the hot pixels on your particular sensor. I see so many people saying they clone them out, and it seems like a 5 minute configuration and then batch mode to take care of all your images at once with the right program or Photoshop plug-in. Does such a thing exist?

Regarding the 1Ds Mk II, I would also agree at that price level I would expect a near flawless sensor, or that Canon would already have mapped out those pixels before shipping the camera.

In the early days of the original 1D, they had quite a little utility disk that let the user make adjustments on the camera. But, and I think it's a good idea, they don't supply that software anymore with the 1-series cameras. And no, the 1D version would not work on the other 1-series cams.

And yes, you can create a PS action to auto-clone that pixel but why? You're talking an $8000, 1-series camera here. Return it to the dealer or send it back to Canon and have them re-map the pixel(s). That's why the camera has a few extra hundred thousand pixels (16.7 effective/17 total).

Oh, I agree, I was thinking it would be a cool utility for the rest of us, not directly aimed at the $8000 camera buyer who definitely deserves the red carpet treatment. I guess Canon figures it's cheaper to send them out and address the problem only for the users that complain about it. Oh well, whatever continues to bring us all these great cameras in the most cost efficient way.

Regarding the utility, I was thinking of something a little smarter than a PS action, that would only do the cloning if the noise matched the noise level you define, like a hot red pixel for example.

I guess that is a little off-topic, but I've been hearing the hot pixel thing come up a lot lately.

I would definately return it :(

What a bummer though.. how long does one have to wait to get the replacement :(

Not off-topic at all. I have also been reading on several forums of pixel issues on the 1DsMKII's.

The trick with hot and dead pixels is one of chance.
On a typical sensor they are trying for a less then 0.01 percent bad pixel. I don't know Canon's specific aim point, but for one of the advanced sensors I worked on that was the goal for an acceptable chip.

So if 0.01 percent of 16 million are bad this means 160 pixels over the sensor , which they will map out and have the software correct at the factory. Then when they ship it they are hoping that none go out before your warranty expires. Even so with that many pixels I will not be surprised that one in ten cameras ends up with some extra bad pixels that are close enough together that they are noticeable.

And for trivia on my 1DsMkII does not appear to be any bad pixels that I can find a this time. If they show up before the warranty is out, you can bet if it is noticeable and confirmable, I will be sending back for repair.

Dead pixel here.. brand new tonight. It seems many are saying that they got one new... with a red pixel (dead). Well I did a huge shoot 2 days ago... all perfect, and then a quick shoot today in studio... and BANG... I have my red beacon!

My camera is a year old... but lucky me, Samy's Camera cleaned it and put a swab into the shutter. So it has a brand new shutter... and I thought (??) a new sensor, but I might be wrong.

I shoot BEAUTY... so absolutely it goes back to Samy's, and they can ship it off.

Any more questions, just ask: bigler.steve@gmail.com

Canon Eos 1Ds Mk 2, and a few lenses. (I should have bought the 24-105 L... but I went cheap instead: 85 USM, 100 USM Macro, 28-70 USM)
My advice.... save your money... buy "L" glass only... and the 100 macro!
