I found this interesting, yet I didn't hear of any widespread problems reported with this. When you read it, it does make sense? Would this be a widespread problem - I think not, 'cause Nikon would have had a recall? And if it were true, I'd be afraid to check because of the length of time I'd have to keep the camera body open for inspection, thereby allowing all kinds of dust to get into my camera.
So far I've managed to avoid the CCD dust pitfall by being exceptionally careful when I put on a new lens.
Any comments or observations about the problem listed on the highlighted thread?
I have not seen any other posts on the internet in relation to that aperture problem. An easy way to test is to just stick on a lens and set the D100 to Aperture priority, then use the Depth of field preview to see if it is opening the lens.
I have seen damage done to the lever by putting on a lens incorrectly or an incapatible lens type.
I experienced that particular problem when I bought a Sigma 15mm fisheye, but I think that was more a lens problem. It seems that the spring that controlled the aperture tab was not mounted properly, so the aperture "sticks" to wide open (f2.8). I've been sending that lens twice to Sigma USA. They did not do a good job in repairing the lens for the first time.

It's not a problem specific to the D100: if you're changing lenses in a hurry, get the lens in the wrong position and use too much force you can bend that lever on just about any Nikon camera.
My dealer told me about a pro photographer - one of their regular customers - who had just bought a D1x and somehow managed to do this: he thought he'd got a faulty camera since the exposures were consistently wrong, so they replaced it. The original was sent back to Nikon who promptly pointed out that there was nothing wrong the camera per se - the aperture control lever had been bent....
I recently had a conversation with Nikon tech support on a different topic (AA batteries not functioning 'properly' in the MBD100); somewhere in the conversation I asked what is the major 'repair' problem Nikon encounters. This is the one. Amateurs and Pro's in a hurry or not being careful/watchful when swapping lenses. Some are repeat offenders, fortunately, as indicated in the posted article the damage most often is not disastrous.
