About a month and a half ago I bought a used D200, with E+ rating, from Adorama. It had 20K shutter activations and worked great, until I noticed a hot pixel. In every image, there was a fluorescent green pixel that would not go away. Happened no matter the image quality settings and no matter whether it was RAW or JPG. So I sent it back and got another new (used) E+ D200 from Adorama which I still have. It only had 200 activations (basically brand new) but again, there was a hot pixel. Not in exactly the same spot, and nothing that a casual observer would notice, but since I know about it I find it difficult to ignore.
In searching online I've found that this is apparently a common issue with DSLR cameras. Most people like Ken Rockwell just ignore it and fix it in Photoshop if they really need to:
I'm wondering if other users here have any advice or information on what to do. From what I've read, these sorts of things can come and go and even if I sent this second camera back and got another one with no hot pixels, it could develop the problem over time. It's really not that big of a deal for me, but I'm curious what others have done when faced with this issue.
