Hello Amita, You might give just a little more detail concerning "communicate" - do you mean P-TTL or TTL or Auto or manual?
I have both AF360FGZ's and AF400T's. I use the AF360's just for daylight flash fill because of high speed synch. I use the AF400T's in regular TTL for receptions and dial in about -2 stops of compensation. So if you'll settle for plain TTL, you can probably get any flash that supports Pentax TTL. If you want P-TTL I think your choices are limited to the AF360FGZ and the new Sigma - I also think Metz is going to release a new adapter that supports it.
