To make a long story short.....I gave a friend an 18-55 lens...I replaced it with an AF-P 18-55mm lens. This lens will work on my 7100 but not on my D90. I didn't know that when I bought it. Anyway, I still need to replace the lens and found this on ebay. It IS an AF-S 18-55mm which will work on both of my cameras but what is the gizmo on the front of this lens?
Maybe some sort of reverse mount macro thing?
Thanks
