Comments on: Dead Pixels on Canon 5dmk2 Image Sensor http://www.tomguilmette.com/wp/my-blog/archives/2054 Cinematographer, Director of Photography, Editor Wed, 15 Jun 2011 00:10:50 -0600 http://wordpress.org/?v=2.8 hourly 1 By: Sam http://www.tomguilmette.com/wp/my-blog/archives/2054/comment-page-1#comment-14051 Sam Thu, 09 Sep 2010 23:19:44 +0000 http://www.tomguilmette.com/wp/?p=2054#comment-14051 Hiya Like others I have stumbled upon this page as I discovered a hot pixel in the 5D I have purchased less than 2 weeks ago. I was testing it side by side doing low light tests in just candle light with REDONE and the results were fantastic. Only later on review I discovered an orangish hot pixel in roughly the center of the clip. I immediately ran a test shooting dark background at different ISOs and it was visible on high ISO settings and not on the low ones. I am gutted but reading about so many people having the same issue I am don't feel so bad now. I have written to the shop I bought it from as they sold it to me with a 3 year warranty. However I wonder if I should contact Canon directly. Other issue is I have left UK where I purchased it and am currently in India where I was to film the movie 5D was bought for. So I have to wait and see what happens. Do they help me out at a local Indian Service center if at all. I will run more tests now with the camera using (and noting) different ISO speeds as well as running the camera for long to see how it responds heated up. If it performs OK in low ISO then it maynot be too bad as I won't like to shoot in low ISO due to grain anyway. Will try and post 'what happens next' here. Still, a fantastic camera btw. Hiya

Thanks for the info. I just took receipt of a new 5D MII today. Without know that this was an issue I started testing out the low light capabilities of the camera. Low and behold during a video test shot at high iso's I found a pretty big cluster (4x4 or so) of white pixels. Instead of packing it all up and exchanging it for a new camera, I opted to just "beat the snot outta this one" and work the gremlins out and send it in for warranty repairs on Monday.

I hope to get it fixed as I only had my camera for about a month. I'm packing it up for another trip to the factory service center. Its about to spend more time at Canon than it has at my house. Wish me luck. Unfortunately, Canon is trying to tell me that having a dead pixel on the image sensor is normal. I hope to get it fixed as I only had my camera for about a month.

I saw it months ago when you first when through it and have been paranoid about this happening to me when I buy my DSLR. Long behold, my beloved 7D, which I've owned less than a month has this issue. I'm going to scan the sensor and map out where the dead guys live and give Canon a call. Thanks for posting all this.
