what is the difference between the Remote Control Set D and the Remote Control Set F? everything i can find out about them makes them seem the same functionally. the Remote Control Set E at least looks like it controls zooming. there isn't a D on the Pentax web site, so it looks like it is an older control superceeed by the F, but nothing says anything that i can see. i know the D can control the *ist and i am guessing the F model will too.
