Kim, you do consistently fine work, and I would often enjoy even more views of your auto subjects, like interiors and dashboards! Keep up the good work!
Thanks to all of you for your suggestions so far!
Today I dug out this 28mm f/3.5 Nikkor-H from my kit bag and it's own Nikon velour-lined vinyl pouch. When I removed the rear cap, I noticed something strange on the metal ring shown in the accompanying photos. It looks as if lubricant seeped out around the screws and dried. The lens has never been or needed serviced, nor has it been used in several years. It literally seems like new in all other respects. Any ideas of the cause of this anomaly, or the safest way to clean it off? Thanks in advance!
Amen! ...and keep up the great work--your auto shots are incomparable!
