Good lord I hate the internet sometimes. The R5 is a stills camera that does video in parts. If you need a video camera, buy one or hire one? The entire premise this camera is being judged and found guilty on is flawed - that it needs to be a professional cinema camera and powerful stills camera. If you need a video camera in the shape of a stills camera, I hear Sony make a good one...
Well said. They will never stop though. People are caught up in emotion and hype. The average person seems incapable of their own nuanced and logical thought process, which is why they give so much time to paid talking heads on youtube. I'm guessing this bashing and trying to change the R5 probably gives them a place to exert force and control in an out of control world these days.
It is pretty clear that the camera performs very well for what it was designed for. I've done my own overheat test and exceeded the record times Canon specified in direct sun and hot ambient air. It will more than cover my needs, and its design point: stills with limited very high quality video, and competent 4k30 and 1080 that you can use to your hearts desire.
I notice that most of the people with the largest issues don't seem to have equipment that can do this today, and their opinions are coming from 100% others reports, not experience. They hate what the cutting edge of hybrids is capable of and blame Canon that their innovation is not enough. They won't just go buy the Sony dedicated video camera either, even though somehow that camera (basically useless for stills) overheats in not much more time and lacks the resolution of the Canon.
Hybrid tools always compromise, which is why there are so many great purpose built tools on the market. We are living at a time when there is unbelievable tool sets for creativity- so many great offerings from so many brands. For anyone who is unhappy with these amazing cameras, I don't think it is the cameras that are broken... maybe it is time to look at who is behind the camera. Find a tool that will work for you and move on.
EDIT: the reports of thermal shutdown after taking fast bursts over and over may mean it is not as good at coolng as a 1DX3, meant for sports and in a giant body, but it also has a high MP sensor and must read out more data per shot. If you just lean on the shutter and go full rate, that buffer is going to run for a long, long time, which is the same as running high frame rate video, especially dual card writing. So no, I am not surprised. Does that make the camera unreliable? Not to me for my uses, I would never shoot thousands of shots in just a couple hours in high rate bursts. It is fair to say it might be unreliable as a dedicated sports camera, just like it is not a dedicated video camera. I think the real problem here is, Canon gave this too much power from the video and sports capable cameras, and now everyone thinks it should do all features as perfectly as purpose built tools for those jobs.
I'd love to see Canon improve things if they can for the R5/6, but I maintain that as the mirrorless 5DV with fast bursts and video supported but not dedicated, this is a great camera for many. I also appreciate all the normal customer reports and non hyped reviews, good or bad experiences, so we can all get the info we need to decide if the camera is for our needs. (Well, I already own it, but for everyone else sake)
