Brand new 1D Mk IIn camera has spots all over images...

Recommended Posts

I decided to upgrade from my 10D to a new 1D Mk IIn. I brought the

camera home, charged the battery and took some pics. Problem was

when I brought them into PS CS2 I noticed something really wrong, the

images had spots all over them. I plugged in the DC coupler and took

a look and there isn't one hint of dust or anything else for that

matter on the sensor glass.

 

What do I do? Help!

Here is an <a href="http://www.photo.net/photo/4273428&size=lg">EXAMPLE</a> of what I am seeing. The image has been converted from RAW and saved as a Jpeg for reference and is full size. The spots I am referring to are mostly located in the upper left of the frame but can be found in other areas of the image as well. I have gently blown the sensor with the air from a bulb type duster and cannot see any debris or dust on the sensor plate at all.

Thanks for the help. I have experience cleaning the sensor on my 10D but would never have thought a camera would leave the factory like this. Moreover; I am surprised it's nothing that I can see... Thanks again for the help. Will let you know how it turns out.

Yes...it is dust on the sensor...

 

I have routinely cleaned my Canon 5D and Canon 10D sensors, using a PEC-PAD wrapped around a modified rubber spatula that has been carefully cut flat, rounded and smoothed.

<p>

I start by carefully blowing off the sensor with a bulb blower, then I dip the PEC-PAD into methanol ("HPLC Grade" Methanol ... very high quality methanol) prior to touching the sensor. Then I gently "swab" the sensor from one side to the other, and then blow the sensor off again. I may (occasionally) need to repeat the process if there are dust specs remaining.

<p>

To see the dust specs, I shoot against a white card at f/16-f22, slightly underexposing to get a light gray image...which makes any dust specs readily visible.

<p>

Again, do this at your own risk. I won't advise you to try to clean your own sensor...but I have done so many times, and it is no longer a scary process!

I completely understand that this might be dust. Problem is, in the past I was able to see the crud on the sensor and the camera had 2+ years of shooting airshows and F1 racing where I changed my lenses in the most horrible of conditions. This camera came out of the box and produced these images as some of it's first! It actually left Canon this way? This leads me to believe it might be more than dust.. but if it is, WTF?

Norman...any chance this camera was purchased and returned prior to your receiving it? My 5D arrived in pristine shape...but then again, I was on a waiting list and received mine at the store on September 29 last year, as one of the first to be shipped.

<p>

Good Luck! I hope you get this resolved. Canon and/or the store you purchased from should certainly be told about this.

Richard,

 

Actually, the store was backordered and waiting on a shipment. I bought it and had the camera drop shipped to me while out of town. I never would have thought that the camera had problems but it was the people in the pro rental dept who I get my specialty glass from that suggested the possibility of it not being dust at all but maybe part of a bigger problem. This is when I panicked.

 

Andrew,

 

I didn't stare lovingly at it.. But I did lock up the mirror and lick it a few times. ;)

Just a short note to say thanks to everyone who kept me from jumping to conclusions with regards to my sensor problem. After a thorough cleaning there still is only one extremely faint spot on the image and after shooting at both ends of the aperture spectrum have concluded that it can only be dust and not dead pixels. I just couldn't (and still cannot) believe that Canon would let a camera leave their factory like that... My 10D was in better shape after 2 years of shooting!

 

Anyway I just wanted to say thanks again to everyone who responded in such a quick and helpful manner. You guys are the best!

 

-Norman
