The DVX100's and the HVX200 use their own prepriotory remote connectors. the 100B and HVX have focus/iris connectors too. Controllers are available from BeBob (FOXI) and Varizoom. - Non have "Push AF" yet, but they do all have manual-auto switches, so you can flick over to auto mometeraly if you want. - a simple "Push-AF" version would rock though!
