The Zacuto eye piece is stupid expensive. The Hoodman is the same thing but $300 cheaper, get the red rock micro loop and your ready to rock. I have been using mine over the HVX, pretty pumped, besides all the ProRes converting. Not a big deal if you have time, if your shooting contest recaps then it is kind of a pain.
read the manuel and you will know that cam like a pro. Make sure you pay attention to your shutter speed.
