Was charging batteries and getting things ready this afternoon for the arrival of my Scarlet tomorrow and figured I'd take a pic of just the accessories needed to be able to shoot with a Scarlet/Epic camera body.
So, you will need:
A lens - I have 2 PL mount there
A screen (touch screen is VERY much recommended!)
Side handle if you want to go mobile (and don't want to invest in v-locks/plates/adapters)
Redvolts for the side handle
Chrager for said Redvolts
SSD cards (you really do need at least 2 unless you like sitting around waiting for transfers)
RedStation RedMag the fastest (and only) way to transfer data from the cards
All in all, about $7500ish extra just to be up and running.
Here's a pic with what is needed for the 7D/5D MK2 I'm shooting along with Scarlet:
Lens -2 Canon L lenses there
A pair of batteries
CF card reader (cheap USB2 one as the firewire one is being used on another shoot)
About $2700 for the Canon(s)
