I seem to have a haze - or slight losss of contrast in the blacks. This seems to only happen on my 70-200 Nikon lens. It is clean. Thoughts?
Only on the 70-200? At all, or a certain focal length? And are you taking interior or exterior shots. Please post an example.
Not knowing where or time of day that you were shooting I will offer this possible cause. Light, sun or man-made, grazing across your front lens element will fog your pictures. As you rotate toward the light beam you can notice in the viewfinder a brief angle that the view is fogged. Some lenses are more prone to this as their front element protrudes further forward than others. You might try installing a Lens Hood and trying a similar shot, same time, direction to see if this is indeed the problem. Also, remove the lens from the camera and look through it to see if the fogging is a problem within the lens itself.

Do you use a lens hood? Does it do this at all f/stops? Does it do this in all modes including M, S and A? Is the VR turned on or off?
I do use a hood and usually keep the VR function on.

Try a few shots without VR. If your contrast improves, it could be a VR problem.

post an example. VR does not affect image contrast and without an example you will be getting other "unusual" suggestions.

Theoretically that is true, but we are in the investigative stage of troubleshooting and NOTHING should be off the table until we find evidence that points us in a direction. Right now, we have insufficient data to draw any conclusions in any direction.

The obvious has no place on the table. I prefer to not go down certain avenues when solving problems, just to say I can rule them out. VR is not something that could ever produce haze in an image. Fungus, dust, etc inside a lens or on the front/rear element, a poor quality filter, smudge on the sensor, pointing the camera at strong light, these are all likelier scenarios which I would look for initially. But without an image you could blame haze on the Northern Lights or the dust from the volcanoes going off, or a cloudy day.

Right, haze cannot be caused by VR. The questioner needs to post an example or two to get useful help. There might need to be two photos, one from the "haze" lens and one from another (same view and time). Otherwise, maybe the best suggestion is that it was hazy outdoors.

Post some pictures and click "store original."
Thank you for posting this question....as I have enjoyed reading the muses from some of our several weegie board disciples.
In all seriousness, it is obviously witchcraft.... No other explanation without further data.
Post two examples. One with the problem and one of the same subject without the problem.
