Just picked up an R5 yesterday, completing my switch from Sony. Haven't really had much of a chance to shoot with it, but I got it set up the same as my R6 so switching between them will be seamless. Looks good so far.
Just some quick test shots of my son with the R5 and RF 70-200/2.8L, RF50 f/1.8 and Tamron 35mm f/1.4:
New to the R5, and the animals have been laying low. Caught a few deer while comparing the 400f5.6 to the 100-400 MKii. Also was visited by the last guy yesterday after getting skunked in the morning. Hope to get some serious shooting in soon.
