Easy to control
NO 4K HDR
Not OK Battery Life for Video
Not huge improve form 5DMK4...
EVF is good than a73 worst than a7r3
I’m A7MK3 and 5DMK4 user, eos R is worst then a7iii at least Sony got 5axis build in, I can use some old lens with out VC or OSS and shoot at night . I’m not Sony fan boy I just telling the truth, also my fd got a7r3 and it got pixel shift , that really useful at shooting stable shoot, making 116mp photo... EOS R I had be using for a week and it expensive I relized -6ev af is same with a7iii... and A7iii got batter ISO and low light preferment whatever photo or video, I guess Sony is the biggest cmos factory in the world, and don’t have wide angle lens for now , but 2875 f2 is great but expensive, I would like to buy a7r3 with Tamron 28-75 f2.8 only 6000... and get good quality,
also the quality just like canon 5DMK4... D!G!C 8 had no huge improvements !! The dynamics rage basically the same ... ask a “video maker” I not recommend you get EOS R because there are less lens for choice and Sony is Doing 6K to 4K... not I sell it to my fd if u are canon fan boy you can buy it
