As of today, Pentax's own website lists only 4 focal lengths of XW as available:http://www.pentax.jp...e/xw/index.html
Those are the 4 focal lengths usable in the Pentax spotting scopes.
The 40, 30, 5, and 3.5 were outside the normal range for spotting scope use.
It may mean they are planning to confine XW availability to only those four focal lengths from now on.
Or it may mean those are the four focal lengths left.
It would be good to get an official statement, somehow.
It's also interesting the spotting scopes are not noted as coming with a Zoom, and the XL 8-24 zoom is not listed on the site. Likewise it's interesting the PF-100ED spotting scope, long-discontinued, is listed.
So I am not certain whether the website is up-to-date.
Their on-line Buy Now website shows more choices:http://www.pentaxweb...ptics/eyepieces
But only the 5mm is "in stock". All the others are listed as out of stock.
