at the risk of passing on uncredited info (and this would appear to be just that) there is a view that Pentax use DA to designate Digital lenses (ie designed for sensor not film), but not neccesarily the sensor format. I found on here some slightly surpising DA lenses considered to be 'FF':
Pentax Lens/Camera Compatibility - Mark Roberts Photography
I believe 200* and 300* definitely are Digital FF comaptible from Pentax sources, but people are right to question how DA lens might behave on a 35mm sensor as opposed to film -
Right now that test cannot be done as a camera to do it does not exist (though Samsung probably have one or two pre-production ones, maybe they would test this for us and let us know?) Although someone clever, on this forum, who knows about optical design might be able to offer informed comment of ray paths and angles of insidence as the designs are in the public domain - I for one would like to know that the DA35 limited and DA70 limited can do Digital FF as they will probably last me a lot longer then the K10 they currently attached to
