Where I'm going to buy it the RP + adapter is US1340 and 6d2 US1360, basically same price. Also lp-e17 and lp-e6 seem to be same price as well. Considering this i was actually thinking of going back to the 6d2. It has a more professional body and I don't lose much, except a few auto focus tricks. 4k is non-essential and rp's 4k is pretty poor. WiXqi.
