Canon EOS Rebel D300 KISS - Mystery Pixels?

Marmbo · 6th July 2004

I've only had my D300 for a few weeks and love it a lot. I have noticed something now however after taking a lot of low light snaps. There seems to be a small blue dot near the bottom middle, and far right almost near the bottom there is an even smaller white dot. These seem to be in all dark photos ( easy to see when leaving the lense cap on ) The single white dot isn't too much trouble to remove afterwards, but the larger blue dot isn't so easy to deal with. This happens on all user selectable modes of the camera.

Any ideas? Should I bring this back to the store for exchange?

Hi.

I think you have a couple of dead pixels in your cmos chip. This means that a couple of pixels in ur chip has spolit. With your lens cap on, take a picture about 10-15 seconds, then you can see the pixels that are spolit. Bring your camera to the canon servicing centre @ lv4 keppel bay tower @ harbourfront. If you have the warranty bring your recept along.

Oops if you are based in singapore then follow the above. You shld bring the camera back to the shop for a 1 to 1 exchange within 7 days of purchase. After that proceed to a nearby canon servicing centre then.

YES!!
In store exchange for another 300D after talking to the Store Manager for like 10 seconds. He had no problem doing it at all for the 1 Month old camera. ( As opposed to 4-6 weeks for service through Canon )

Took the new one home, charged both batteries all up and took photos with the lens cap on. No more image abnormalities.

I'm a happy

Canon

owner once again.

Yes. Store was FutureShop in BC, Canada where this all happened.

The new Camera I thought had no problem, but doing some long exposures last night, I noticed different pixel problems now on the CMOS sensor. For quick snaps there doesn't seem to be any issue. When there is longer exposure ( The longer, the more noticable but it gets bad at 1+ Second ) There is now a grouping of two red pixels that get brighter and a few instances of a single white pixel after 2+ Second exposures start to show up when taking shots in complete darkness. ( At night, with lens cap on )

Looks like I'll go back to the store and test one in stock to see if it exhibits teh same thing. I really assume this is NOT NORMAL for these cameras to be doing? Or it something that is common with DSLR??
