I'm new here, and I've been looking for a solution to my problem when I found this forum.
Last october I bought a new Mark II and was very happy with it. I use it for work, filming everything from tv ads to weddings.
This last week something came up on my screen. Some purple dots appeared on the center top of my images. It is visible not only in my photos or videos, but also when you turn on the camera on live view. And it appears with any lens I use.
Is this what you guys call hot/stuck pixel?
Here's a photo for you to see.
At first they look like black dots of smudge, but if you zoom in to its original size or more, you can see they're purple/reddish.
I read about laser damage to the cmos, but all images I found are very diferent from what I have.
I tried the sensor cleaning option on the camera, but it didn't do anything for me. Do stuck/hot pixels only appears after the photo is shot or is it already visible in the lcd in live view mode?
Can anyone help me? I'm going crazy here...
You can ask Canon to fix the camera. They will merely map out the bad pixels so they no longer show up. As time goes on, its possible that more will appear. Its not a big issue for still images, since noise reduction removes them easily, but it is a problem for video.
