Yesterday I got my D5100 back from Nikon Repair for a focus tweak and was trying it with various lenses. Focus looked good but a strange thing happened. I had a Tamron 70-300 mounted and had snapped several pictures which were OK and then all of a sudden a photo was way dark. I looked at my settings on the LCD and they looked right so checked the data and found that I had shot at 1/2500 of a second. I metered again and LCD showed 1/60 so shot another photo and still way dark. I again took a look at the settings on the LCD which continued to read 1/60 of a second. I then replaced the lens with a Tamron 10-24 and all was well. I checked it with a Nikon 18-55, a 35 1.8, a 55-200 and again the Tamron 10-24 which all worked well. I re-installed the 70-300 and it worked just fine. Today I installed the Tamron 70-300 again and it worked as it should. What in the world would cause the camera to meter at one setting and the lens stop down to entirely different setting?
