<p>Thanks for the replies, but still not what I'm looking for. The ad shows a side view of the mount, clearly marked "M2 Nikon Japan", so is probably an extension tube. As I suggested, to move the Kenko pinhole further from the film plane.<br>
I've done pinhole photography in the past, including using a body cap with an etched pinhole in stainless steel, and having a "co lens" mounted in front, which sharpened the image greatly; I sold that off some time ago. I mostly want to know about the quality of the Kenko pinhole attachment and if the M2 will work on my D80.<br>
The seller only wants $40 for the F50, extension tube and the Kenko. But if the Kenko will only produce fuzzy photos, I am not interested.</p>
