down load this for liveview and basic controls via your laptop. If you want to go BULB mode for longer than 30 seconds you have to turn live view off and and use an intervalometer but the shots do download direct to your laptop for viewing. Ive been using it for years now.
Only just upgraded to a Canon in fact it worked so well.
