Saw a mention of this on the pentax.de website, so went searching.
It's made by a company called UK-Germany and appears to be able to take most moderately sized lenses (remember you're limited to autofocus though!) - the DA 14, D-FA 100 and 50 macros plus the DA 18-55 all fit as examples.
Can't see any references to depth ratings or such.
Here's the site: www.ukgermany.com/
and photos are available at: http://www.uk-germany.com/english/uwg_pentax_istDs.html
Anyway, it looks pretty cool to me - who's gunna get one and give it a go? q-:
Cheers, David
