I'm a car guy and I like going to weekly Car Cruise Ins and photographing the more interesting cars and their details. So I headed out to the local Sonic drive in last night and started shooting with my D7000 and the 18-140 kit lens. I use it because it's the widest I own and it is VR. About 1/2 way through the night my AF stopped. I checked to see I didn't hit a button or switch by accident. Turned it on and off, took the lens off and back on no go. So I finished using MF.

Went home tried my 35G and it worked so Thank God, not the body. I then cleaned the contacts on the lens using an eraser ✏️ still no go. Finally I wiped the contacts on the body and lens using contact cleaner on a Qtip. That did the trick. Saved me sending it back to Nikon Service out of warranty or buying another lens. Just an FYI story. BTW I handle my equipment very carefully and try to never change lenses outside, always use caps.

A pencil eraser contains pumice, an abrasive.

OK...... If you use an abrasive, as opposed to a solvent, on a plated contact (and most are), you can severely damage the contact. Repairs might be somewhat expensive.

Usually inside environments are containing more dust than outside ones!
