Pentax PF-DS1 (69561)

A superb design for use with Pentax's awesome PF-series of 65mm, 80mm & 100mm spotting scopes, the PF-DS1 adapter is specified to work with the Optio S, Optio S4, Optio S4i & Optio S5i point-&-shoot digital cameras. However, since it threads directly into the eyecup-side of the XW and XF series eyepieces, it seems that the PF-DS1 could be used with any device that accepts traditional 1.25 eyepieces(provided, of course, you were using that device with the XW or XF series Pentax eyepieces).
