Re: Sensor types longevity

I can't offer any quantitative info, but I did manage to damage the sensor 
on my old CoolPix 990.  I had been using it in manual mode with a fairly 
slow shutter speed (I think 1/15th) and wide aperture (I think 
~f3.5).The next day I took it outside and decided to put the wide angle 
adapter on it.  I managed to snap the shutter while pointing the lens 
directly at the sun.  Starting with that snap, and on every shot after, 
there is a magenta circle in the frame.  I noticed it when I dumped the 
files onto my PC a couple of days later, and was able to go back through 
the files and see exactly when it happened.

Fortunately it is near the edge of the frame and not terribly huge but it 
has been a PITA since then...

Here's a quick snap that shows the problem:

How susceptible are they to bright light damage?
Is degradation, if any, slow through the life of the unit

Do colors change/shift, does sensitivity change, or both?

Nope. Bottom center, a little to the left.  The arrow is pointing at it.

I gotta admit, it was a challenge to shoot.  After I drew the arrow on the 
light table, I had to take several shots from various positions to get the 
spot to line up right.
