But...at the same time you have one of the best 4k HQ in the market with stunning sharp and detail, much better than the A7s3. due to the Downscale 8k to 4k. And if you use an atomos ninja V you will have more than 3 hours recording without overheating! The thing is to solve the problems! And they have solution. Unfortunately the only thing it doesn´t have solution is the 4k120fps...
But man....getting a huge stills camera with the best AF! With a stunning Animal EYE AF which works just wonderful! To get Dual pixel AF...to get all that video quality....And yes to get a stunning 8k!!! Ok...camera has some overheating problems? Yes it does. But I think we need real test to see if it is such a pain or not! And we work around it! If you are a professional in video, just grab another camera...For example, my plan is to work with the R5 and the R6. The R6 video is superb! They will overheat both, but using an external recorder will solve my problems!
I believe that this camera is not for everyone, and thats normal! If you shoot for long periods like interviews and you want to work in 4k, then maybe the Sony is better choice. But then again....Who records more than 3 hour straight?? With the Atomos you can record 3 hour 4k HQ....The best 4k in the market! And you still can have a huge stills camera! So..............Come on, this EOS R5 is a beast! a BEAST!
