Nikon lens AFS 70-200 VR DX 2.8 mm problems
This has ALWAYS been a great lens, but now a problem has arisen. The lens takes washed out over exposed photographs. I thought at first it was my cameras (D90 and D7000) but it was not. I have taken the same photograph with my prime 18-105mm lens on each camera and all is OK.
I have tried all the option wheel settings with the 70-200 but all have the same problem, a washed out overexposed photograph.
I wonder if I am overlooking something, dirty lens to camera contacts? Some background menu attribute that has changed? (surely not on two cameras). Light leak on lens somewhere? I have tried various S speeds and A settings and ISO’s and it does not help the outside photograph
This SAME lens takes a good photograph inside the home OK and it is not over exposed???
ANY IDEAS!!!! I have never had a Nikon lens do anything like this.
Samples attached from same camera.

Try setting camera on a tripod and using exposure delay are timer if this fixes the problem it could be a sluggish iris if it does look into the lens and watch the iris when taking a 1/2 sec exposure at maybe f16 if the iris does not close down it is a stuck or sluggish iris in lens. Worth a try.

Was the settings set in manual in both pic, , if so try taking the over cooked one again in. Auto and another in P mode

I had the same problem while walking up the Mist Trail in Yosemite National. I was walking up to Nevada Falls and looked in my viewfinder and saw nothing but washout. I thought maybe I ruined my 24-70mm F2.8 MKII. Took a shot same results. It was going to be a long three miles down the mountain w/o my short lens. 5min later I tried another shot, perfect. Not sure what it was? Thinking it was condensation due to temperature change, happens a lot when I go to Alaska.

I would check the diaphragm on your lens. I suspect that it is really not stopping down or is only partially stopping down when you take pictures outside. Inside where there is much less light and the picture is usually taken at a lower f-stop and the diaphragm doesn't have to close down much. You can check the lens by removing the lens and set it to the highest f-stop. Then move the little lever the camera itself move to stop down the lens to determine if the diaphragm actually closes down. Try doing this with both your lenses and compare the results.

thanks to replies
Will try the dry out method first. Set on table with sun shinning through the window and our AC on and see if that will take any moisture out. It is the time of the year here in Missouri to turn on the air anyway.
thanks again

Ck Metering/exposure in menu an set it back to factory setting. ev button on the camera changes it back to more realistic numbers in exp and shutter speeds, these can override the cameras' computer Easy exposure Compensation, forgetting to "turn off" EV changes after you've moved to a different shooting environment is the primary cause of over and under-exposure

Had the same issue with my older 80-200.
Sluggish diaphragm blades.
Had it cleaned/repaired.
Though the focus is different, the OP's overexposed tree photo appears to have shallower depth of field than the normal one which would back that theory up.

Check the metadata and see what aperture the image was taken at. If it shows wide open you may have a diaphragm issue on that lens. Or it could be a contact issue between the lens and the body.

I sent to Royal Camera service for repair. It had a number of problems. The lens was returned in excellent working condition and operates like a new one. I have used their service before and it has always been excellent.
Thanks to everyone for their advice and experience.
