Pentax 1.4X HD-DA Rear Convertor usage

As a potential buyer of the new 1.4X convertor I thought it would be helpful to see what the results have been using this convertor with Pentax lenses.  What's been your experience with yours?


I already have the 1,4X and 1.4 XL and would like to have the AF ability of the HD-DA but am concerned about of this convertor with the 600mm f4.0 FA lense.


Questions to Ricoh USA resulted in 'we don't know' regarding usage with the 600mm.


Your input sought.

Works very well with the DA*300.  There is a post on PentaxForums from a photographer who is using it with the FA*600.
