I was looking in some boxes at my Mom's house and found a Nikkor relic of my Dad's in an unlikely place. It probably dates from the mid-1970s. It's a Nikkor Close-Up Attachment No. 2 (3.0 Diopter). Happily, it screws onto my 18-55mm kit lens and works just fine without any special attention. These quickie snaps show the effect. The first shot shows the minimum distance with the 18-55mm, the second shot shows the minimum distance with the Attachment and the third shot shows the package. A pretty neat find on a rainy afternoon.
