Took the R for an extended test drive after I scored a great deal on a used body and the Ef mount adapter. I like it so much I'm shifting my Sony gear to get the R5. I'm preordering the second its available. Hopefully I can get it in September as I'm guessing it'll be in short supply for quite some time. I almost bought a Blackmagic Pocket 6k for raw video, but the R5 will serve me better in both stills and video, plus it'll allow me to consolidate my camera/lens lineup and workflow. None of the 1dx3 "gotchas" bug me outside of the size, OVF, fixed LCD and flippy mirror. I'm just not into DSLR's and 20mp isn't enough for me. Anyway, I'm expecting something similar from the R5, some warts but none that are dealbreakers. I'll have plenty of time to evaluate all the blogger hype before preorders open. But it'll have to be a major turd for me not to buy.
Cheers
Chris
