Thanks for your impressions.Apart from less MPIX its a big step up from the 5DIV if you shoot action or use fast primes wide open. AF is in another league and I love the new control options.
I also want more MPIX - however, due to the special memory card and the need for a new card reader you pay a lot on top for the R5. As I am waiting for the high MPIX "R", the R6 is a great option.
With the R6' fabulous DX sensor I can use Gigapixel AI, when I need more MPIX. Works for me. YMMV.
TBH I was never MP hungry and thought that 20 would be enough. But shooting more and more dragonflies and birds I need some more than the R6 can offer. Not neccessarily the 45 the R5 has, but something around 30, at least.
But most frustrating is the overall high R/RF pricing - lens - bodies at all.
Maybe within a few years... And my guess is that my first R will be an RP successor: small FF travel cam - but with better sensor and hopefully with IBIS.
